Norman from The Big O rides a Cool Bike which comes equipped with a rocket launcher, and the bike in question seems to be pretty durable and maneuverable, given how it went toe to toe with freaking Megadeus in a highway chase scene and had not a scratch on it by the end thanks to Norman's driving.
The first appearance of Hyoma Nagare from Combattler V had him riding a bike and performing crazy maneouvers with it.
The first time we saw Kenichi Go from Voltes V he was practicing in a firing range by shooting AND riding at once.
Kaneda's red motorbike in AKIRA most definitely qualifies.
FLCL: Haruko's yellow vespa is also undeniably cool, which is interesting as it's a scooter.
Soul from Soul Eater too believes in the power of cool bikes, which is why he has one.
Some of the D-Wheels from Yu-Gi-Oh 5Ds would probably fall under this trope, especially since some are designed to be some of the coolest wheels in the anime: one based on the ride of the hero in Ghost Rider, a dragster, a steamroller... After all, cool bikes MUST be the centerpiece on an anime which features card games on motorcycles.
Many of them have awesome names to boot, whether in the series itself, as with Dark Glass's "Delta Eagle" and Jack Atlus's "Wheel of Fortune", which in the dub has its name changed to "Phoenix Whirlwind", or in supplemental material. Some of the other names include the main character's "Yusei Go", which appears to be a reference to "Speed Racer", as well as Blackbird, The Beast(dub-series only, unnamed in the original), Giganto L, T-666/Terrible Omen, and Bloody Kiss.
Orbital 7, Kite's little robotic assistant in Yu Gi Oh Zexal can turn into this.
A subversion in Durarara!!. Celty's Cool Bike is actually a Cool Horse disguised as one. You can tell by the fact that it makes no noise, only whinnies and it has the shadow of a horse.
Beelzemon of Digimon Tamers has a cool, living bike called Behemoth. And if you aren't Beelzemon, it will possess you and drive all across the landscape.
And better, it wasn't made for him or anything like that. Beelzey was just the only one powerful enough to tame the cursed bike that had terrorized a town with its original rider (and then Guilmon, who knocked the original rider off only to become possessed himself.)
éX-Driver (or, to capitalize it properly, éX-Driver) is an anime about cars - the glitch-prone AI-controlled ones all normal people drive, and the old, all-manual sports cars the protagonists drive in order to catch the aforementioned AI ones. So it's all the more surprising when one of the protagonists turns up on a Ducati, which has a lot less trouble catching the runaway cars than the old cars do.
Jun the Swan's G3 from Science Ninja Team Gatchaman. It has portable buoys that when lowered under the bike can allow it to ride on water surfaces. Later in the series, it gets a missile launcher.
The motorcycles ridden by Toho Heavy Industries' artificial humans in Biomega.
Heat Guy J: Daisuke Aurora has one massive ride, plus a Cool Sidecar for his android partner J to ride. It is loaded: massive engines for incredible speed, heads-up display, converts to an even more badass mode when J rides it, and it's amphibious!
Bakugan New Vestroia gives us Mira, a Badass Biker girl who rides a Subterra colored motorcycle in her first appearance.
Gundalian Invaders give us new forms of Battle Gear, the Mobile Assault Gear. And what do Drago and Talean ride? The motorcycle based ones.
Ghost Rider's bike is cool mundanely. It's even cooler in Ghost Rider mode, what with the chains and skull and flames. And it leaves a trail of flaming tire tracks... and can ride up even vertical walls.
Johnny and Danny's bikes represent two distinct types - Johnny's is a chopper, while Danny's is a speed bike.
In the German comic Werner: Lots. The fact that Brösel is a motorcycle nut and draws extremely realistic (but often still wacky) bikes helps a lot.
Werner's bike in the first book, Oder was?, was a fictional Horex Regina made up in the fashion of US choppers of the 1970s, complete with a long springer fork and Iron Cross rear-view mirrors. Werner says he rides Horex because he gets sick from riding BMW. He also has a personal dislike against Harley-davidson.
Toddl's T-shirt: On the 8th day, God created Harley Davidson
Werner: He must've had a bad day.
In the second book, Alles klar?, he got the same Horex Regina 400 chopper that Brösel was working on, only in the state the bike would have been in, had it ever been finished the way it was planned, including a candle as a headlight. This was also the first book in which Brösel drew Harleys for almost all the other bikers, sometimes tricked out in ludicrous ways (fuel tank that's half aquarium, sidecar made of a small wooden door, an armchair, footrests, a wheel, and an ashtray, red lantern for tail light, and so on). In one story in the fourth book, Eiskalt!, it was equipped with gimmicks such as the Wurstblinker (sausage blinker - yep, a blinker that shoots sausages and other food items) which reappears in the tuned-up version in the first movie, Beinhart!
The fourth book also featured the "Red Porsche Killer", a Horex made for defeating a 1972 Porsche 911 S owned by Brösel's publisher and "manager" Holgi in a race. Four (!) Horex Regina 400 engines rebuilt out of aluminum and stroked from 400ccm to 610ccm each were built into a dragster frame painted metalflake pink. The "Red Porsche Killer" was built in real life and actually ran two races against said Porsche.
After years of riding Horex, Werner decided to build his very own motorbike in the late 90s. The heart of this machine was a 1000ccm (61cui) single which gave it the name "Satte Literschüssel"; when it was built for real, it turned out this behemoth had a displacement of 1444ccm (88cui), still in one cylinder only. The motor was so big that it became a supporting part of the frame. Other features included a fork mostly made of wood and a shovel blade for a seat. The Name "Satte Literschüssel" is also a wordplay with "Satelitenschüssel" which means Satelite Dish.
Around the same time, Andi built the tiniest bike of the Wernersen (Feldmann) fleet, the Notkessel. A motorcycle mostly made of stainless steel, even smaller than a Honda Monkey, but powered by a 175ccm Honda twin which looks almost huge in the tiny frame. Despite being quite tall, Andi can actually ride it, and it appears in some comics, too.
As revealed in the documentary book Die Kulteisen der Wernersens, Andi built quite a number of other more or less weird bikes before the Notkessel, for example the Vampire, a bike made of parts Andi just had lying around, including two complete BSA power plants.
Then there was the Dolmette (see Chainsaw Good) which wasn't designed by either Feldmann brother for a change but by an engineer from Dolmar (Hamburg). There's little that's cooler than a motorcycle with 24 working engines.
Another wacky idea was the Heizölkessel, based on a vibration-free parallel twin engine with two crankshafts prescribed by a doctor and acquired at a pharmacy. Due to a crazy bet against speedbikers, Werner rebuilt it to a turbocharged diesel and fit it into a comfortable chopper frame. This bike sort of came true, too: It is named Neander and built by a Kiel-based company. It does have a working two-cylinder, twin-crankshaft turbo-diesel with lots of horsepower, and it is currently the second most expensive production bike in the world.
The Remnants have some pretty sweet rides, too— naturally, there are at least two high-speed chase-battles.
In the 2007 TMNT CGI movie, in his Nightwatcher guise, Raphael rides a motorcycle covered with plate steel. Michelangelo himself comments on how awesome this is.
Aachi and Ssipak loves this trope seeing as how every character has a cool motorcycle or at least motorcycle-like vehicles. Special mention goes to the character of Geko, a Bad Ass cyborg who has a bike with plenty of weapons.
Films — Live Action
The BMW R 1150R Rockster used by Ben Affleck's character in Paycheck.
Marlon Brando riding a Triumph Bonneville in The Wild One is one of the events that started this trope.
Will Smith's character's Black MV Augusta F4 in I, Robot.
The Bike that is built into the front steering system of the Batmobile in The Dark Knight, referred to officially in the movie as the "Bat-Pod". It features built-in autocannons and apparently sports a gyro-stabilizer for the driver and engine, allowing it to make impossible turns, recover from wipeouts, and drive straight up a wall, flip over upside-down, and land upright again.
We see it return in The Dark Knight Rises, and has the distinction of being the only Bat-vehicle that survives through more than one movie in the Nolanverse.
Steve McQueen's stolen Triumph SR6 650 in The Great Escape. Pure Rule of Cool. There's nothing like that whole scene at all, in the book the movie was based on. But the chance to put Steve McQueen on a Triumph for a chase scene was simply irresistible.
Possibly the best-known film motorcycle, Peter Fonda's "Captain America" chopper from Easy Rider. Both this and Dennis Hopper's more conservative chopper started life as Harley Davidson Hydra Glides.
The Lightcycles from TRON. They're fast, deadly, and fold right up into the handlebars for easy storage!
In TRON: Legacy, the motorcycle Sam rides in the opening is his own. It's later established that Sam inherited his dad's insanely-fast Ducati, fixes it after it's been sitting in a shed for 20 years, and is even more of a daredevil with it than his old man was. Likewise, the comic based on Tron 2.0 establishes Jet's ride of choice as one of these. It ends up saving their butts on the Game Grid.
Torque has plenty of very nice bikes, but the turbine-powered Y2K definitely takes the cake.
Fiona Volpe's BSA Lightning with the built-in missile launchers in Thunderball.
The police hoverbike from the latest Star Trek film. The trailer even made it seem as if the cop was a robot with a metallic voice. Since Trailers Always Lie, the cop in the actual movie had a normal voice.
They don't ride motorcycles, but the bikes in Mystery Team ARE pretty cool.
The green Harley-Davidson WLA Liberator that Captain America rides in Captain America: The First Avenger. It even comes with machine guns, and a rope-launcher.note Which Cap uses to great effect against motorcycle-ridng HYDRA mooks late in the movie.
Young Boris's rather satanic looking bike from Men In Black 3.
In Return of the Jedi they introduce speeder bikes. Back then they may have been a reference to horses, but in the prequel trilogy and the expanded universe they are treated like motorcycles, complete with speeder bike gangs.
"The Return of the Jedi Sketchbook" has many concept drawings from the movie development, and the comments mention custom and hotrodded motorcycles. They're definitely not referencing horses.
In Spy Kids 3D: Game Over they have a race utilizing cool vehicles, specifically motorcycles. Kinda weird that they have that much experience driving and riding when most of them don't look old enough to get a permit, but hey it's a video game.
In X-Men, the Cyclops' motorcycle that Wolverine *ahem* borrows to get to the train station.
In The Lost Boys the eponymous vampires also ride cool bikes. In the novelisation David's bike is explicitly mentioned as being a Triumph.
In G.I. Joe: Retaliation a motorcycle that splits apart and turns into explosive projectiles is used by Firefly to help break Cobra Commander out of prison.
In Snow Crash, Hiro Protagonist's smart bike has its own operating system. And Raven's bike. You know, the one with a hydrogen bomb built into its sidecar.
Sirius in Harry Potter had a flying motorbike, which he gave to Hagrid to help him get Harry from Godric's Hollow to his uncle's house. It appeared again in Harry Potter and the Deathly Hallows, where Hagrid used it to get Harry safely from his home to the Weasley's house. In the end Harry inherited it. A Triumph Bonneville and a Royal Enfield were used for the films.
The bike created by the Librarian, and ridden by Death in Soul Music. It actually falls to bits quite early on, but the idea of the bike remains, resembling light reflecting off a gleaming machine, only without the machine. Unfortunately, because it was created in accordance with rock music tropes, it isn't designed to slow down, much less stop safely. It's meant to crash at the end of the eighth verse. Eighth, as the whole sequence is an extended tribute to Meat Loafs Bat out of Hell, down to the silver black phantom bike.
And because eight is a magically significant number in the Discworld.
In Robert Asprin's Phule's Company, CH (Chocolate Harry) gets official permission to use his personal hoverbike instead of a Legion vehicle.
Kamen Riders, obviously (that's where the "Rider" comes from); while the main Rider always has a Cool Bike, more recent seasons have started to introduce Second Riders who don't have them. In order:
The Showa Riders' bikes typically just have custom cowlings, due to special effects limitations of the 1970s, though they're all faster and more powerful than standard bikes, sometimes allowing them to ride along walls and up cliff faces. X-Rider's can be used as an underwater vehicle and Super-1's actually flies using rockets. The bikes were a much bigger part of the series in the earlier years; more recent seasons have it as The Artifact (how many times did we see Kamen Rider Kiva's bike, three?) It may have something to do with the Rider helmets losing the eyeholes.
Kuuga's TryChaser 2000 can combine with the sentient mecha-beetle Gouram, giving it extra armor and blades on the front. Partway through the series it's damaged and rebuilt as the BeatChaser 2000, which is also affected by Kuuga's Mid-Season Upgrade Rising Forms.
Agito's Machine Tornador can become a hoverboard. G3, Gills, and Another Agito have custom bikes (GuardChaser, Gills Raider, and Dark Hopper, respectively) modified to resemble them.
Ryuki's and Knight'sBond Creatures could become motorcycles when in Super Mode - still remaining very much sentient. All Riders in the series have access to a common type of bike called the Ride Shooter, taking the Rider through the portal to the mirror world. The American adaptation Dragon Knight actually added more, by having the characters' normal motorcycles transform along with them when they became Kamen Riders. The Riders also have awesome real-world bikes during non-spandex time. There's an awesome scene near the end with six Riders, finally on the same page - even The Hero and the Evil Twin! - riding out of M.I.B. headquarters unmorphed as a Cool Bike-riding, cool jacket-wearing squad, ready to kick butt and take names.
More bike awesome from KRDK: Mirror world bike chase. The sneaky Torque found out that Xaviax is too smart for The Starscream, and new The Dragon, polite but sociopathic Strike, is hunting him. Torque rides for his life, and on the street, it looks like a guy riding crazily for no reason. Only we can see that in the reflections in doors and windows, Strike is right on his tail. Torque eventually thinks he's lost Strike, when several stories up, the reflected Strike emerges into reality and drops in right behind him.
Faiz has the Autovajin, which can transform into a robot with its own AI; in this form one wheel is a Gatling while the other is a jetpack and its handlebar becomes Faiz's Laser Blade. Its highest-priority directive is not "obey Faiz." Kaixa's Side Basshar turns into a walker mecha with tons of missiles that can deploy even more missiles. Delta doesn't get a unique bike, but he's usually associated with the Jet Sliger, a rocket- and weapon-laden behemoth every Rider apparently has but only he really uses. (Faiz has one, but it gets blown to scrap in its introduction episode during a battle with Delta. Kaixa presumably has one if the other two do, but it is never summoned.) Also, its wheels are spheres, and it can travel sideways if desired.
The BOARD Riders' bikes can all channel the power of the Rouze Cards, allowing the Riders to use them for special attacks. Chalice's, like the later Dragon Knight, is an ordinary bike that changes when he does.
Hibiki is the subversion; he gets a completely unmodded Honda Valkyrie Rune (see below under Real Life). This presumably plays into the fact that Hibiki, unlike his fellows, is not a Badass Biker. (He's certainly a badass. He just can't ride all that well.)
Kabuto and Gatack have their own custom machines (Kabuto and Gatack Extender) which can transform into more battle-oriented forms, Kabuto's gaining a battering ram and Gatack's turning into a flying hoverboard; they're also affected by the Riders' Clock Up systems. The other Riders simply get slightly customized versions of the common Machine Zectron bike.
Kiva's Machine Kivaa has the brain of a horse monster, turns invisible at high speed, and has an enhancement booster that nullifies wind resistance. It's also the only chopper-style Rider machine, and is generally awesome-looking. Ixa's Ixalion, despite the cool name, is simply a custom bike; Saga doesn't have a unique bike, but Taiga owns a Honda DN-01, which he never uses as Saga.
Decade's Machine Decader can transform into past Rider machines via AttackRide cards; Decade changes it into the Autovajin in the first episode and the Side Basshar in the Grand Finale movie.
Double's HardBoilder is modular, its rear half being swappable with jetski and flight wing attachments; it's also armed (machineguns in all forms, plus torpedoes for the water form). Accel is his own Cool Bike, and can combine with the sentient tank Gunner A for combat situations (he also owns a red Ducati called the Diablossa which he uses as a civilian). Skull's SkullBoilder is essentially the same as Double's bike without the option parts.
OOO's Ride Vendor, as the name implies, can change into a vending machine which dispenses can-shaped helper robots called Candroids. Interestingly, the Ride Vendor is mass-produced by OOO's support organization and anyone with appropriate clearance (and Cell Medals) can use one.
Kamen Rider Core from the Double/OOO movie was a monstrous...thing made from the dark memories of all Kamen Riders powered up by a few Core Medals. It could turn the bottom half of its body into a flaming motorycle.
Fourze's Machine Massigler, fitting with the show's theme of space travel, is shaped like a shuttle and is spaceworthy; the Powerdizer exoskeleton can even transform into a launchpad for the Massigler. Meteor has his own ride, the Meteorstar, which is styled like a satellite.
In Super Sentai and Power Rangers, most teams had at least one or two bikes. Some teams would get a full set of bikes for each member Sixth Ranger often being left out if there was one), while other teams only had bikes for certain members, forcing the others to ride on a sidecar equipped on one of the bikes or use a different vehicle. However, they were gradually phased out in the the late 90s and 00s in favor of more fantastical vehicles or upgrades to their mecha. This wasn't much of an issue for Power Rangers, where the teams mainly used teleporters in the early seasons and the bikes were only kept just for the toys. However, several seasons gave everyone (or almost everyone) a bike where Sentai did not.
Power Rangers also had no less than fiveflying bikes, each for a single Ranger in its season (Wes, Cole, Hunter, Ethan, and Will). They'd transform from motorcycles to various types of flying gear. Funnily enough, they seem to be the one piece of gear exempt from the Protagonist Powerup Priveledges, as the latter three went to The Lancer instead of the Red Ranger. There's also Carter's Trans-Armor Cycle, which turned into armor and extra weaponry.
Whether it's cool or not is up to the individual, but the most unique bike was the one belonging to the Omega Ranger / DekaBreak. It was a motor-unicycle! And those actually exist, some looking quite like the one in the show. Also, Omega Ranger's/DekaBreak's Humongous Mecha is a giant motorcycle that other robots can ride.
Then Came Bronson, a lonerWalking the Earth action-adventure show starring Michael Parks that ran for only one season in 1969 and '70. He does his wandering on a 1969 XLH 900cc Harley-Davidson Sportster.
Happy Days: The Fonz. In one episode, Richie acquires a bike of his own and asks Fonzie whether he thinks it's "nice". Fonzie's reply is the page quote.
Tin Man : DG's ride of choice appears to be a vintage 40's era motorcycle. It's also implied by her interaction with Officer Gulch that she Drives Like Crazy on it.
House MD series 2 has its medical diagnosis genius protagonist, Gregory House, buy a used 2005 Honda CBR1000RR Fireblade in Repsol race replica colours. He gets the bike at a good price as it's had an accident with very minor cosmetic damage that is not noticeable in later episodes. He adds to the coolness of the bike by stating its top speed as 180 mph, not 160 as presumed by his best friend, oncologist Wilson.
In the Babylon 5 episode "Eyes", Garibaldi and Lennier assemble from parts a black 1992 Kawasaki Ninja ZX-11. Garibaldi thinks it's too bad they can't ride it since they've got no gasoline, but Lennier had the forethought to install a power source of Minbari design. Leading to a Crowning Moment of Funny when Ivanova says she's glad life on the station is back to normal ... then Garibaldi and Lennier go zooming by.
In Crusade, Captain Gideon goes for a cruise through an abandoned alien city on a flying motorcycle, complete with shades and a leather jacket. He ends up having to use the jetcycle to evade alien Attack Drones that try to shoot him down, escaping only because his bike was smaller than they were.
The Top Gear "1949" episode involves a race from London to Edinburgh (some 400 miles) in state-of-the-art vehicles of the time - Richard was ecstatic over choosing the legendary Vincent Black Shadow, but soon came to regret the decision over the long, long ride.
In the last episode of iCarly: Spencer is restoring a motorcycle for Socko's cousin Ryder, a 1964 Sterling, which is actually a Triumph like Fonzie's, but when Socko and Ryder get in a fight Socko lets Spencer keep it, who then gives it to Sam.
Sons of Anarchy is made of this trope. The titular bikers mostly ride custom Harley Davidson Dynas, with a few exceptions.
While most of the main cast tend toward Cool Cars, Doug Penhall of 21 Jump Street instead rides a Triumph Bonneville.
Richard Thompson's song "1952 Vincent Black Lightning"
Said Red Molly to James that's a fine motorbike A girl could feel special on any such like Said James to Red Molly, well my hat's off to you It's a Vincent Black Lightning, 1952
The late Taiji Sawada, who was a ''bosozoku''Badass Biker that liked both Harleys and Hondas, was occasionally known to include his Cool Bike of the day in videos for X Japan in his tenure there, as well as in at least two photoshoots. It can be seen in the PV for Week End in the background of his character's death scene in the video, and it also makes an appearance in the Celebration PV.
Steve Jackson Games' catalog once contained a fictitious entry for Kung Fu CB Mamas on Wheels vs. the Motorcycle Aztec Wrestling Nuns. Despite not actually being a real game, if it did exist, it would have had one side entirely on Cool Bikes.
LEGO Technic and LEGO Racers have produced many fine and crazy bike sets.
Millennia from Slizers had two forms, one of which was a large, wide-wheeled bike ridden by his small robot form.
Robo Riders were bizarre, alien, motorbike-shaped Humongous Mecha. A strange but fine idea, however the even weirder execution (not giving them characterization and having the riders be the wheels... oh, and the wheels are also the ammunition) lead to the line becoming a failure because kids didn't know where to put the concept.
The Triumph Bonneville ridden by Eva/Big Mama and the Speed Triples ridden by her subordinates in Act 3 of Metal Gear Solid 4; it helps that they're also real world cool bikes.
Test Drive Unlimited 2 features three bikes as a new DLC pack, the Trope image Harley above and both a Ducatti Diavel Carbon and a Desmosedici RR that can pull off wheelies. Unfortunately, they require Atari Tokens to unlock. Meaning you have to pay real money for them.
Being a game centered around a whole collection of badass bikers, The Lost And Damned has no shortage of cool bikes, ranging from classic 1950s/1960s-style Easy Rider and modern custom choppers to exotic Italian and Japanese crotch rockets.
Sonic & Sega All-Stars Racing gives Shadow a SECOND motorcycle as his standard vehicle.
Mario Kart Wii introduced bikes to the series. Especially cool ones include the Sneakster, Spear, Wario Bike, and Bubble Bike.
Mr. Grimm of Twisted Metal is always driving some variant of a weapon-equipped motorcycle. Always.
Bayonetta gets to ride a Cool Bike for a little while midway through the game. Later, so does Jeanne when she rides up the side of a rocket to rescue Bayonetta and stop the awakening of Jubileus.
Saints Row 2 introduced a selection of cool bikes, from Harley Davidson choppers to Japanese racing bikes. The coolest, however, would have to be the Kaneda, ride of choice for Ronin leader Shogo, which features neon trims and the ability to ride up walls.
Full Throttle, a game about a biker gang's Bad Ass leader Ben, naturally features a variety of Cool Bikes. Ben's eventually gets the (limited) ability to fly, even.
Road Rash 64 has the "Insanity Mode" bikes named "Executioner" and "Hammerhead". Both bikes can travel upwards of 200mph. A skilled player can utilize their speed to jump over entire sections of some courses with them (including bypassing long winding turns and mountains). The Executioner appears to be a V-24 engine with wheels and a seat. The Hammerhead is a more high-tech bike that appears to have more of a jet engine. The bikes are, in fact, too souped-up for regular gameplay, but can be obtained from the beginning with a cheat device such as the Gameshark. In order to even hope to do well on most regular tracks with them, the player will have to lay off the throttle for most of the game. Jumping over a car at full speed may cause the bike to fly so far off the course that the player will not catch back up to the other racers.
The Flare-S Swoop from Jedi Academy is a Star Wars version of a sport bike, with mounted blasters. In the Zonju V mission, the protagonist rides it in a fight/race to the death with the Star Wars version of Hells Angels.
In Kingdom of Loathing, playing as the Avatar of Sneaky Pete gives you access to Sneaky Pete's trusty motorcycle, which has a built-in AI and a soothing female voice. As you level up, you can trick out the motorcycle with a variety of gadgets.
The SWAT Kats Cyclotron. Launches right from the Turbokat... Comes in both one and two seat varieties, has all sorts of weapons, fires miniature versions of a lot of the Turbokat's missiles. And it has a jet engine.
Biker Mice from Mars, where the Cool Bikes used by the protagonists were not only cool, and armed to the teeth, but sentient as well.
From Code Lyoko, Ulrich's "Overbike". A mono-wheeled, flying bike with a reactor. Virtual, but certainly cool. It has a real-world close equivalent◊. Main difference is the color. (And that it doesn't fly, obviously.)
In the later seasons of ReBoot, the virus Megabyte gets an upgrade from cool limo to Cool Bike, which is later acquired by Andraia. In her own words: "Now that is a nice bike!◊"
Legends Of Chima has the Speedorz, one wheeled motorcycles that make the sound effects of their tribe's beasts.
In the Grojband episode "Soulin' Down the Road", Mina rides a motorcycle with a sidecar.
Although all bikes are generally cool, there are some models that are quintessentially cooler than the rest. They tend to have the name "BMW" (Eg: the R90/S, the K 1200R, R 1200R and the R 1150R Rockster), "Triumph" (namely the Bonneville, the Daytona, and the Speed triple), "Ducati" (Particularly the Monster) or "Harley Davidson" on them.
The Can-Am Spyder built by BRP. One look at it will tell you why.
Subverted though in that since it's technically a trike, certain motorcycle enthusiasts mock Spyder owners for "wanting to ride a motorcycle, but they don't actually get a motorcycle". Also in some states, you don't need a motorcycle license to ride one.
"MV Augusta's" F4 and Brutale bikes. They only make a handful of these per year, by hand.
The BMW R75◊ and Zündapp KS-750◊ couple from World War II were more about utility than coolness, yet they were the workhorses of the Wehrmacht, they had an automobile-like powered rear axle, locking differentials, offroad gears and usually could go where no sane driver of a Jeep or Kubelwagen would ever attempt to.
The modified "Indian" Scout used by Burt Munroe at the Bonneville salt flats; it still holds the land speed record for motorcycles under 1000cc.
Hendersonfour-cylinder◊ motorcycles were among the earliest brands to hit regularly 100 mph in full road trim, which made them the favorite brand of police forces in the 1920s. Before Harleys, Moto Guzzis or even Indians.
The "Vincent" Black Shadow
The Y2K bike, due to it being powered by a jet turbine from a helicopter.
Dodge Tomahawk◊. It uses the exact same engine that the Dodge Viper sports car does. What sort of engine is that, you ask? A V-10. A very high-displacement V-10. Unfortunately this makes the bike a case of Awesome, but Impractical, as the weight and size of the engine meant that it had to have 4 wheels and the fuel tank had to be mounted way at the front to avoid the heat the engine gives, and has a fuel economy figure of about 60 feet to the gallon.
You could be forgiven for believing it safer to just take the warhead off a missile and ride that instead. (It'd probably still be just as safe with the warhead left in place.)
Bimota's Tesi line of motorcycles, especially the Tesi 3D◊, with its much sleeker looks compared to its predecessors - The idea behind the design seems to be to put as much emphasis on its two-wheeled-ness as possible without impairing its functionality as a speedbike.
The unique front suspension (technically called a hub-center steering system) also serves a practical purpose: the traditional front suspension, consisting of telescopic forks, have a constantly varying rake (degrees from vertical) as the bike pitches forwards and backwards, which can upset the bike's handling. The hub-center steering system maintains a constant rake, preventing this.
One does not talk about cool bikes without mentioning a Confederate.
The 1999 Suzuki Hayabusa is the only street-legal motorcycle in the world capable of going faster than 300kph. The main reason for this is because in 2000 all the motorcycle manufacturers agreed to install safety measures to prevent bikes from going above that when they realized that few people can safely handle bikes going faster than that.
