10 Badass Motorcycles That Redefined Crotch Rockets!

These Models Completely Changed The Crotch Rocket Game

Crotch Rocket - 1998 Yamaha YZF-R1

The crotch rocket has come in various forms over the past decades but there were a few models that really changed the game. Some of these revolutionary sports bikes brought sophisticated aerodynamics to the table, others championed the use of innovative on board technology, but they all managed to take the idea of speed to the next level.

Since the first crotch rocket styled motorcycles appeared on the scene, the big manufacturers have been trying to get one over on their rivals in one form or another, so we’re going to look at some of the sports bikes that totally transformed the landscape. But before we get started, what exactly is a crotch rocket? You’ve heard the term, of course, but what does it really mean?

What Is A Crotch Rocket?

The less than reliable Urban Dictionary defines it as “a specific type of motorcycle, typically distinguished by its aerodynamic ‘hunched-over’ seating position and high power to weight ratio. Crotch rockets are not always Japanese motorcycles, Italian companies such as Ducati manufacture quite high-quality crotch rockets as well.” The entry also adds that the term is “often used in a derogatory manner,” and it is a derogatory term really, because calling something like a Ducati Panigale a crotch rocket rather than a highly-engineered, state-of-the-art, performance motorcycle seems rather unfair.

That being said, the term “crotch rocket” is widely understood and recognized, so we’re going to run with it. Oh, and if the Urban Dictionary definition didn’t satisfy you, here’s the Collins English Dictionary version, which essentially says the same thing: “a high-speed, high-performance motorcycle characterized by an aerodynamic body shape which requires or encourages the driver to lean forward.”

So, we’re looking for game changing motorcycles complete with an aggressive riding position and aerodynamic fairings. For that reason, we’re not going to be including some motorcycles that might normally appear on a list discussing the evolution of the crotch rocket. The Honda CB750 and the Kawasaki Z1 won’t be making the cut, though they’re definitely important figures in the sport bike timeline – the Honda 750 in particular – but to call them crotch rockets is quite the stretch of the imagination.

With that in mind, like all lists, the content is subjective and there may be one of two models missed, and perhaps even a couple that got included that don’t deserve to be – but generally, we think we’ve ticked the right boxes. Let’s take a look at the 10 motorcycles that redefined crotch rocket motorcycles.

10 Innovative Motorcycles That Evolved The Crotch Rocket Ideal

#10. The 1984 Kawasaki GPZ900R

The 1984 Kawasaki GPZ900R was the first real crotch rocket, and the grandfather of modern sports bikes. If you don’t know it as the GPZ900R, then you might remember it as the Kawasaki Ninja 900 – that’s right, this was the first ever Kawasaki Ninja, and if that doesn’t make it warrant a place on the list then we don’t know what would. But wait, there’s more. Not only was it the first Ninja, the GPZ900R also boasted some incredible technological advances that would help pave the way for the modern crotch rocket.

Powered by the world’s first 16-valve, liquid-cooled, 908cc inline four-cylinder that had a maximum power output of 115 hp, 63 lb-ft of torque at 8,500 rpm, and a top speed of over 151 mph, the Kawasaki GPZ900R was years ahead of its closest rivals. The first Ninja, the first real crotch rocket, and definitely a game changer. And of course, it was featured in Top Gun – so that should be another valid reason to put it on the list, right?

#09. The 1985 Suzuki GSX-R750

We started with the first Ninja, but what about the first Suzuki GSX-R750? The 1985 GSX-R750 is arguably one of the most important motorcycles in the evolution of the crotch rocket. Unlike other sports machines of the early-80s, the GSX-R750 was light, agile, handled exceptionally well, had huge power, but with brakes that were actually useful. Weighing in at a mere 385 lbs, dressed to impress with aerodynamic fairings and a race-inspired livery from Suzuki’s XR41 endurance machine, this truly was a race-ready but road legal crotch rocket.

Race aerodynamics, an aluminum frame, lightweight 18 inch wheels, and an engine that could make grown men weep – boasting 106 hp from its oil-cooled 747cc inline-four engine, a top speed of around 160 mph, all wrapped into a very svelte and nimble package. Even compared to today’s crotch rockets, the original GSX-R750 is still pretty light on the scales. However, it’s the powerful performance, the lightweight chassis, and race-ready technology, wrapped in an affordable, road legal package, that makes the GSX-R750 a revolutionary crotch rocket. It’s no wonder that the legendary Suzuki GSX-R750 has been in constant production since 1985 to the present day.

#08. The 1992 Honda CBR900RR

If you ask anyone to name an iconic crotch rocket from the 1990s, you can bet that they’ll name the 1992 Honda CBR900RR. Designed by Honda’s incredibly talented Tadao Baba, the CBR900RR was developed simultaneously with the RC30 and NR750, and originally was planned to be a 750 – but Baba had other plans and upped the displacement, and Honda’s first ever “RR” CBR model was born. This particular model was revolutionary because it wasn’t developed for racing and watered down for public consumption – it was built purely for the road.

What really made it special was its 893cc inline-four engine – not particularly groundbreaking, sure – but when combined with a lightweight chassis that was focused on agile, nimble handling, a new breed of crotch rocket was born. Weighing in at just over 400 lbs dry, the CBR900RR was the first motorcycle to offer the kind of power you’d expect from a 1000cc motorcycle, but equipped with the agility and responsive handling of a 600cc machine. The first, and certainly not the last, but without the CBR900RR, modern crotch rockets may have evolved differently. It’s one of the most badass motorcycles in history.

#07. The 1994 Ducati 916

Next, we have the Ducati 916. To some, the Ducati 916 was the most influential crotch rocket of the early 90s – and that’s a fair point. If you thought sports bikes were all about inline-four engines and Japanese engineering, think again. This beautiful motorcycle from Italy was powered by a stunning masterpiece of an engine engineered by Massimo Tamburini himself. In fact, it was the most powerful twin-cylinder engine in its day, producing a mammoth 108 hp at 9,000 rpm, with the 916cc desmodromic twin taking advantage of liquid-cooling, ram-air induction and electronic fuel injection.

While the engine is easily the most important feature of the Ducati 916, let’s not forget its other exquisite features, such as its slim line profile, aggressive headlights, and single-sided swingarm. A success in the design department, a success on the road, and an absolute demon on the track too, with the Ducati 916 winning 4 Superbike World Championships. While some people attribute the success of the 916’s design to the Honda NR750, we disagree and say that the Ducati 916 is one of the most influential crotch rockets ever designed – and in its own right too.

#06. The 1998 Yamaha YZF-R1

The first iteration of the Yamaha YZF-R1 took the world by storm when it first rolled onto the scene in 1998. It was powerful, it was beautiful, it was a force to be reckoned with, and it was almost impossible to find a review of it that didn’t contain the words “madness” and “pure insanity” or something to that effect. For a motorcycle built at the tail end of the nineties, you can still take one to the track and put the fear of god into motorcycle riders showing off on newer models. Though it was considered a hard beast to tame, the early Yamaha R1s were easy to ride, comfortable, vibration-free, and just as good in traffic as they were knee-down mid-corner.

This was at a time when 140 hp was considered insane, and we might laugh at that now, but very few of us have ever put a crotch rocket through its paces properly, and 140 hp was more than enough for the average rider then, as it still is now. Powered by a revolutionary engine that was far more compact than ever seen before thanks to a stacked gearbox arrangement, the inline-four engine claimed 150 hp at the crank, 72.7 lb-ft of torque at 8,250 rpm, that propelled the original Yamaha R1 top speed of 168 mph. At the time, it was pure madness…and when you think about it or take this Yamaha crotch rocket motorcycle for a ride today, you’ll agree that it still is.

#05. The 1999 Suzuki Hayabusa

And then there was the Suzuki Hayabusa, the speed demon from hell itself. This one should be a controversial entry because while the Hayabusa is unquestionably one of the most innovative and important crotch rockets ever built, it also caused a whole decade of design stagnation thanks to its outrageous performance statistics. Let’s start with the good points. The 1999 Suzuki Hayabusa was quite the thing.

Powered by an unremarkable 1,299cc inline-four engine, the Hayabusa’s combination of sophisticated aerodynamic design and ram-air system allowed the engine to produce a record-setting 173 hp at the crank, which translated to a fearsome top speed of 195 mph (depending on who’s talking), and a quarter mile time of less than 10 seconds, the Busa was a speed marvel. And it wasn’t just fast either – it was a great all round motorcycle that was comfortable, reliable, economical-ish, and handled quite well too. But there was one problem – it was just too crazy for some manufacturers.

Fearful of an import ban to Europe for fast, large displacement motorcycles, the main manufacturers got together and informally agreed to limit the performance of their production crotch rockets to a top speed of no greater than 186 mph (there and abouts) and a maximum power output not exceeding 200 hp. The Suzuki Hayabusa was certainly a game changing crotch rocket, but through the years 2000 through 2010, it might not have been for the better.

#04. The 2009 BMW S1000RR

In 2009, a new player appeared on the sports bike scene, and a new crotch rocket rode into town. While BMW are one of the most well-respected motorcycle manufacturers of all time, the Bavarian firm hadn’t ever entered the crotch rocket arena until 2009 with their S1000RR model. They might have arrived about 30 years behind everyone else, but it meant that BMW could jump straight in at the deep end, without having to make any mistakes. The S1000RR was a serious super bike from day one.

Mechanically, it wasn’t particularly different from your average crotch rocket – four-cylinders, stacked gearbox, 16 valves, etc – but BMW managed to make the most of it, and produce a class leading 190 hp at the rear wheel. With impressive fuel injection, advanced on-board technology, and a solid gearbox, the S1000RR rolled onto the scene and straight into the history books with its power and performance – but what makes it revolutionary? It ticks all of the usual crotch rocket boxes, sure, but BMW managed to take the same template and rebuild it into something not-Japanese, in a relatively affordable package.

#03. The 2011 Ducati 1199 Panigale

The Ducati 1199 Panigale was one of those bikes that just rolled in and re-wrote the rule book. While it may not have redefined what a crotch rocket was, it certainly redefined what a crotch rocket could be, and that it sometimes pays off to forge your own path rather than follow the usual trend.

The 2011 Ducati 1199 Panigale was bold, brash, and exotic. Disregarding normal frame construction in favor of a monocoque arrangement bolted directly on to the Panigale’s thumping V-twin engine, an engine that boasted the biggest bore, largest valves, and the fastest engine speed of any twin-cylinder motorcycle engine ever produced at the time, and wrapped in gorgeous bodywork and powered by sophisticated electronics, the Panigale was a revolutionary machine.

With a claimed 195 hp, 98.1 lb-ft of torque at 9000 rpm (from a twin) and equipped with electronically adjustable suspension, a full electronics suite that included ride by wire, electronic engine braking, traction control, racing ABS, and more, the 2011 Ducati 1199 Panigale was less of a crotch rocket and more of a technological marvel. But no matter what you call it, we can all agree that it was nothing less than revolutionary.

#02. The 2017 Ducati 1299 Superleggera

To be honest, this should be tied with the BMW HP4 Race but since both are pretty much unobtainable for the average rider, maybe we shouldn’t include either? No, these new superlight machines have to be included because while they may not be available to everyone today, who knows what tomorrow will bring? What was once reserved for professional premier class racers back then is now standard equipment on most modern crotch rockets, so maybe the full carbon frame will eventually trickle down to the common rider?

As for the Ducati 1299 Superleggera, when Ducati pulled the covers off of it and explained what it could do, we were blown away. In essence, you’ve got an $80,000 crotch rocket that produces an incredible 215 hp, wrapped in a carbon fiber chassis that weighs a paltry 343 lbs, and comes equipped with a sophisticated Ducati Corse-developed Bosch Inertial Measurement Unit that controls all of the bike’s electronics, allowing you to actually use all of that claimed power, rather than just fishtail into an expensive crash. Revolutionary? Certainly. Expensive? Most definitely. Available to all? Give it time…

#01. The 2015 Kawasaki H2R

In a list discussing revolutionary crotch rockets, there can only be one winner: the Kawasaki H2R. Not H2, we’re specifically talking about the H2R – although both are fantastic machines. While the H2 is road legal, we’re looking at the closed-circuit only H2R, both come equipped with a 998cc inline-four, four-valve DOHC engine, and they both feature something quite remarkable: a two-speed centrifugal supercharger, making both models the first production models to feature a supercharger.

The engine in impressive alone but when paired with such cutting edge electronic accoutrements such as a top-class ABS and traction control system, Kawasaki engine braking control, a bi-directional quickshifter, electronic steering damping, and launch control, you know you’re dealing with something more advanced than your average superbike.

In fact, when you place that package into an aerodynamically designed, carbon fiber body complete with aerodynamic winglets to produce essential downforce at high speed, you know you’re in the presence of something more technologically advanced than the average rider can handle. The H2R boasts 310 hp at 14,000 rpm, 115 lb-ft of torque at 12,500 rpm and a proven top speed of 255 mph. If that’s not a revolutionary crotch rocket, then we don’t know what is. While its technology is beyond the reach of the normal day to day rider, we can’t help but wonder what the future will bring? Will other crotch rocket manufacturers bring a model to the fight? Will superchargers become the norm on regular road motorcycles? Only time will tell, but it looks like we’re in for an interesting two-wheeled future.

As the fastest crotch rocket available, is it the best crotch rocket for sale? If speed is your thing, then this is undoubtedly the motorcycle for you.
