When too much is just right: The 2021 Kawasaki Ninja H2 and H2 Carbon
There is absolutely no point in trying to explain why anyone needs so much power, but Kawasaki fully understands, we just do. Thankfully we have this Japanese-made, alien-styled supersport street beast to fill this instinctual biker need.
Powered by a Supercharged, 998cc, liquid-cooled, 4-stroke DOHC 16-valve In-line four-cylinder engine, making 228.0 HP (166.4 kW) @ 11500 RPM, and 141.7 Nm (104.9 ft.lbs) @ 11000 RPM of torque. This is flat-out bonkers Kawasaki, and I love it. Available in a standard version, and a Carbon version, the differences truly come down to exclusivity.
There is no weight or performance advantage to the Carbon model, but you do get a full carbon fiber cowl like the H2R, special silver-mirror paint with a matte element, and individual numbering, with a serial number stamped on the supercharger plate. This is the highest performance model, legal on the street, in the 2021 Kawasaki lineup.
Kawasaki has always been a manufacturer that meant business when it came to performance. The Ninja lineup has had turbochargers in the past, but when introduced in 2015 with a supercharger, it was clear Kawasaki was looking to deliver the king of the streets. This is not a moto GP machine with mirrors and turn signals, the H2 is meant to scare the PC crowd, and keep you screaming like a madman under your visor with every twist of the wrist.
The 2021 Kawasaki Ninja H2 and H2 Carbon starts at $29,500 USD / $33,000 CAD and $33,000 USD / $37,000 CAD, respectively.

2021 Kawasaki Ninja H2 and H2 Carbon Features
Assist & Slipper Clutch
Under normal operation, the assist cam functions as a self-servo mechanism, pulling the clutch hub and operating plate together to compress the clutch plates. This allows the total clutch spring load to be reduced, resulting in a lighter clutch lever feel when operating the clutch.
When excessive engine braking occurs – as a result of quick downshifts (or an accidental downshift) – the slipper cam comes into play, forcing the clutch hub and operating plate apart. This relieves pressure on the clutch plates to reduce back-torque and helps prevent the rear tire from hopping and skidding. This race-style function is particularly useful when sport or track riding.
Economical Riding Indicator
While effective vehicle speed and engine speed may vary by model, paying attention to conditions that cause the “ECO” mark to appear can help riders improve their fuel efficiency – a handy way to increase cruising range. Further, keeping fuel consumption low also helps minimize negative impact on the environment.
Electronic Throttle Valves
Electronic throttle valves also enable more precise control of electronic engine management systems like S-KTRC and KTRC, and allow the implementation of electronic systems like KLCM, Kawasaki Engine Brake Control, and Electronic Cruise Control.
Kawasaki Engine Brake Control
KLCM (Kawasaki Launch Control Mode)
KCMF (Kawasaki Cornering Management Function)
• S-KTRC/KTRC (including traction management and wheel lift management)
• KLCM (including traction management and wheel lift management)
– Designed to optimize acceleration from a stop
• KIBS (including pitching management and corner braking management)
• Kawasaki Engine Brake Control
KTRC (Kawasaki Traction Control)
Less intrusive modes maintain optimum traction during cornering. Designed with sport riding in mind, they facilitate acceleration out of corners by maximizing forward drive from the rear wheel. And because Kawasaki’s sophisticated software bases its dynamic analysis on the chassis’ orientation relative to the track surface (rather than relative to a horizontal plane), it is able to take into account corner camber, gradient, etc., and adapt accordingly.
In the more intrusive modes (and for some models, in any mode), when excessive wheel spin is detected, engine output is reduced to allow grip to be regained, effectively enabling riders to negotiate both short, slippery patches (train tracks or manhole covers) and extended stretches of bad roads (wet pavement, cobblestone, gravel) with confidence.
Models equipped with IMU incorporate chassis-orientation feedback to offer even more precise management.
One of the greatest benefits of designing the supercharger in-house and tailoring its design to match the engine’s characteristics was that engineers were able to achieve high-efficiency operation over a wide range of conditions – something that would not have been possible by simply dropping in or trying to adapt an aftermarket automotive supercharger.
The importance of high efficiency in a supercharger is that, as the air is compressed, power-robbing heat gain is minimal. And while many superchargers are able to offer high-efficiency operation in a very limited range of conditions, the Kawasaki supercharger offers high efficiency over a wide range of pressure ratios and flow rates – meaning over a wide range of engine speeds and vehicle speeds. This wide range of efficient operation (similar to having a wide power band) easily translates to strong acceleration. The supercharger’s high efficiency and minimal heat gain also meant that an intercooler was unnecessary, greatly saving weight and space, and enabling the engine’s compact design.
