2021 Kawasaki Ninja H2R Sports Motorcycle – Features and Specs
Engine
The Kawasaki Ninja H2R engine should be small and powerful enough to match the speed of the Moto GP bike. It was decided that a supercharger was needed, but an existing supercharger alone would not suffice. The engine is intended to withstand 1.5-2 times the pressure of an engine of the same capacity.
For high-speed engine response, the inertial moment of the crankshaft was kept as low as possible and paired with a lightweight flywheel. The rotating mass is also modest, which adds to the fast handling properties. Dual secondary balancers keep engine vibration to a minimum.
For extremely high temperatures generated by the engine, cast pistons perform better than forged pistons. The unique method of casting produces hollow sections to achieve maximum thickness while losing weight.
A V-tube on the second piston ringland reduces blow bye and oil consumption by preventing the upper ring from fluttering. The piston is cooled by two oil jets per cylinder. The bottom of the piston dome is sprayed with one nozzle, while the exhaust side under the dome is sprayed with the other.
Using a large, deep sump oil pan helps cool the oil. To avoid cavitation, the oil pump is always covered by oil, thanks to the oil pan design.
Supercharger
The centrifugal-type supercharger was designed and manufactured by Kawasaki and had a pumping capacity of more than 200 liters per second, with air reaching a maximum speed of 328 feet per second at a maximum atmospheric pressure of 2.4 times.
The crankshaft drives planetary gear, which, thanks to the expertise of the Kawasaki gas turbine and aerospace, rotates a 69mm impeller at approximately 130,000 rpm. Since the supercharger is so efficient, the compressed intake air is heated slightly, so no intercooler is required. To help offer superior productivity, the Carbon Fiber RAM air intake duct provides fresh air to the straight supercharger line through a non-woven fabric filter.
Digital Fuel Injection
50 mm throttle valves are highly accurate, resulting in smooth engine response. The technology further improves S-KTRC input while also adjusting the Kawasaki launch control and Kawasaki engine brake control.
A high-pressure fuel pump is used to increase the power of the supercharger.
Moto GP Inspired Clutch/Transmission
The compact clutch includes ten contact plates to help handle the engine’s ample torque, while the Kashima coating on the housing and hub allows for smooth disconnection and better longevity.
When shifting down, a “slipper” clutch is used to limit the backtrack to help reduce the rear wheel hop. Brembo radial-pump master cylinder provides smooth and hydraulic clutch activation for excellent linearity. Quick gear changes are accessible with a cassette-style gearbox.
Kawasaki Next Level Electronics for the Track
Because of the programming that offers the ECU a precise and real-time picture of what the chassis is doing with minimal software, Kawasaki’s state-of-the-art electronics have always performed well on track. Thanks to the latest iteration of Bosch IMU and Kawasaki’s unique dynamic modeling software, Ninja H2’s electronic management technology has moved from setting-type and reaction-type systems to feedback-type systems to the next level. This increased capability allows riders to make the most of the Ninja H2 on the track.
Inertial Measurement Unit (IMU) (KP)
IMU calculates inertia in five axes: longitude, transition, vertical speed, roll rate, and pitch rate. ECU calculates the Yao rate with Kawasaki’s unique software so that the six-axis chassis can provide lean angle and deceleration / acceleration force for more accurate electronic auxiliary riding control.
IMU enables KTRC to add additional feedback to help speed up the turn on the race track.
Kawasaki Cornering Management Function
The Corner Management Function employs KIBS and KTRC to help racers follow their chosen course around the corner of the track and reduce the tendency to get up when applying the motorcycle’s brakes. Based on the motorcycle’s leanness and pitch angles, IMU helps the system maintain maximum hydraulic pressure.
Kawasaki Launch Control Mode (KLCM)
KLCM electronically adjusts engine power to help reduce wheel spin and therefore limits front and lift when launching from stops, assisting riders by maximizing speed from stops.
Kawasaki Traction Control (KTRC)
Multi-level modes give riders more options, each mode offers a variety of interventions to meet riding conditions and the rider’s desire, and all levels aim to limit output in the event of a high-speed slide.
Riders can choose between three settings, each with a different amount of interference. For nine other locations, each mode has three additional rider-selectable levels that add more or less interference. Riders can also choose to turn off the system.
Chassis
The trail frame is made of high-tensile steel, in which the diameter, thickness, and bend of each piece of pipe are carefully adjusted to provide the desired stiffness.
High-speed track riding is possible because of the ideal stiffness balance, which can absorb external shocks while maintaining stability.
The slim frame design and horizontal positioning of the diecast aluminum rear frame allow the rider’s legs to reach the ground quickly. The concave shape of the trail frame allows air to circulate through it, which helps to dissipate engine heat.
Suspension
The Uni-Trak® Linkage rear suspension system gives KYB rear shock progressive action, so the smaller pieces are gently wetted, and the larger ones are heavily damped for a smoother ride and better steering and handling.
The swing arm of the H2R is one-sided. It is made of forged and pressed aluminum pieces and is extremely strong and lightweight.
Aerodynamic Bodywork
Functional design improves track stability and enhances engine cooling efficiency.
To make it as light as possible, the upper firing is made of carbon fiber. A chin spoiler is integrated into the upper cowl to help create a lower force for better speed stability. To minimize drag, the air scooped by the chin spoiler is carried to the sides using special air channels. Kawasaki’s aerospace division built a dual-blade winglet on the side cowl and extra wings on the upper cowl to increase the force below.
Brembo® Brakes, including Kawasaki Intelligent anti-lock Brake System (KIBS)
Brembo Slima Monoblock Calipers with Four Anti-30mm Piston Clamps Large 330mm Brembo Discs are radio-mounted 4-piston front brake calipers for excellent braking force. The outer edges of the discs feature interstitial ducts to help dissipate heat.
Brembo’s radial-pump master cylinder and reservoir have been improved to make a significant front braking force with light movement of the lever.
For extra braking confidence, the KIBS High Precision Anti-Lock Brake System provides smooth feedback and a little lever pulsing.
