2021 Ninja H2R


Built Beyond Belief

The development of the Ninja H2R motorcycle goes beyond the boundaries of any other Kawasaki motorcycle. Born through the unprecedented collaboration between multiple divisions within the Kawasaki Heavy Industries, Ltd. (KHI) organization, the world’s only limited production supercharged hypersport model represents the unbridled pinnacle of Kawasaki engineering, with astonishing acceleration and mind-bending top speed suitable only for the track.

The Super Charger

The supercharger used in the Ninja H2R was designed by Kawasaki motorcycle engine designers with assistance from other companies within the KHI Group, namely the Gas Turbine & Machinery Company, Aerospace Company, and Corporate Technology Division. The highly efficient, motorcycle-specific supercharger was the key to achieving the maximum power and the intense acceleration that engineers wanted to offer.

High-Speed Stability

The objectives for the Ninja H2R’s chassis were to ensure unflappable composure at ultra-high speeds, offer cornering performance to be able to enjoy riding on a circuit, and finally to have a highly accommodating character. 

The Aerodynamics

To be able to operate in the ultra high speed range, a combination of high power and slippery aerodynamics is needed. Assistance from Kawasaki's Aerospace Company was enlisted in creating the aerodynamically sculpted bodywork to ensure maximum efficiency.


Impeller is formed from a forged aluminium block using a 5-axis CNC machining center to ensure high precision and high durability. The 69 mm impeller features 6 blades at the tip, expanding to 12 blades at the base. Grooves etched into the blade surfaces help direct the airflow. Impeller’s pumping capacity is over 200 litres/second (measured at atmospheric pressure), with intake air reaching speeds of up to 100 m/s.  After passing through the supercharger, air pressure is increased to as much as 2.4 times atmospheric pressure.

Trellis Frame

Using a trellis frame construction offered an elegant, lightweight solution to meeting the performance requirements for the chassis.  Able to harness the massive power of the more than 300 PS engine, it has a balance of stiffness and flexibility that enables a very high level of stability while being able to handle external disturbances at ultra-high speeds.  Its open design also effectively dissipates heat.

The Kawasaki River Mark

The Kawasaki River Mark is a long time symbol of the Kawasaki Heavy Industries Group dating back to the 1870s. As a policy, the use of the Kawasaki River Mark on products is rare and limited to models with historical significance.

The Engine

The Ninja H2R power unit is loaded with technology developed specifically for this supercharged engine.  In order to accommodate the higher air pressure from the supercharger as well as ensure a high reliability with the over 300 PS output, the whole engine was designed to be able to handle stresses 1.5x to 2x greater than on a naturally aspirated litre-class engine.


To facilitate smooth, quick shifting, a dog-ring type transmission was selected.  This is the kind of transmission commonly found in MotoGP or Formula 1, and was developed with feedback from the Kawasaki Racing Team.

KQS (Kawasaki Quick Shifter)

The Ninja H2R is fitted with a quick shifter. Complementing the engine’s strong power and the dog-ring transmission, a contactless-type quick shifter enables quick upshifts for seamless acceleration.

Steering Dampener

Kawasaki’s electronic steering damper was jointly developed with Öhlins, one of the most popular and respected manufacturers of steering dampers. Electronic steering damper provides just the right amount of damping based on what the bike is doing.  Using input from the rear wheel speed sensor (provided via the engine ECU), the electronic steering damper’s ECU determines the vehicle’s speed as well as the degree the bike is accelerating or decelerating.

Mirror Paint

The mirror paint used on the Ninja H2R was developed by Kawasaki specifically for motorcycles.  Its highly reflective, glasslike metal appearance adds to the bike’s stunning design.  While paint similar in appearance may be found in custom circles, this is its first use on a mass-production vehicle in either the automotive or motorcycle industries. Strict Kawasaki quality control measures ensure a long-lasting finish.

Wheels & Tyres

Cast aluminium wheels were designed specifically for the Ninja H2R. Star-pattern 5-spoke wheel design was selected based on analysis and testing to determine the optimum rigidity balance for high-speed performance. The Ninja H2R is equipped with slick tyres. The Bridgestone RACING BATTLAX V01 commercially available superbike racing tyres are rated for ultra-high speed operation.

Downforce Generation

In order to maintain both straight-line stability and the control to change direction while running at ultra-high speed, a number of aerodynamic devices ensure the front wheel has strong contact with the ground. In place of mirrors, the Ninja H2R features wings mounted on the upper cowl. 

Rear Suspension

KYB fully adjustable mono-shock rear suspension offers superb stability. Top of the rear shock mounts to the Swingarm Mounting Plate. 


A pair of massive ø330 mm Brembo semi-floating discs with a thickness of t5.5 mm deliver superb braking force. Dual radial-mount Brembo cast aluminium monobloc calipers grip the front discs. The highly rigid opposed 4-piston calipers with ø30 mm pistons contribute to the Ninja H2R’s superb braking force, as well as a high-quality image Brembo radial-pump master cylinder and reservoir receive extra attention before being shipped to Kawasaki. 

Front Suspension

KYB AOS-II racing suspension. Designed for low friction, the ø43 mm front fork offers superb action: smooth initial action is followed by strong damping at the end of the stroke.

Ninja H2R Bottom Line

  • The Ninja H2R is a closed-course model; it may NOT be ridden on public roads.
  • The Ninja H2R is a mass production model with a VERY limited number of Ninja H2R motorcycles available in Australia.

Ninja H2R Cautions 
 The Ninja H2R is a closed course riding use only model and is not manufactured for use on public roads, streets or highways. All usage of this vehicle should be limited to riding on a closed course.
 The H2R was designed to carry the operator only. Do not attempt to ride with a passenger. Do not ride this vehicle in the rain.
 Parts designed specifically for the H2R are for closed course riding use only and cannot be purchased without proof of H2R ownership (product registration, VIN confirmation, etc.).
 Exhaust Sound
 The exhaust sound level of the H2R at the time of factory shipment is 120 dB/A using Auto Cycle Union (ACU) guidelines. It is the owner’s responsibility to confirm that noise regulations of closed courses permit vehicles reaching this level of exhaust sound. Changes to the exhaust system may alter performance and sound level.
 Usage, Maintenance and Warranty
 As a closed course riding use only model, specific procedures must be followed when riding and maintaining the H2R:
 Vehicle Tyres:
 The standard tyres are designed exclusively for use on a closed course. These specialty tyres are not designed for oval or partial oval course use and may not be suitable for other courses or conditions. Kawasaki recommends that you follow the tyre manufacturer's instructions and warnings, and that you consult the tyre manufacturer to select the appropriate tyres for the course or riding conditions.
 Computer-controlled systems such as KIBS, KTRC, etc are tuned to the standard tyres. Use of tyres other than the standard tyres could affect performance of these systems.
