Kawasaki ZX-10R Ninja

Kawasaki’s cutting-edge electronics have always excelled on the track due to the highly sophisticated programming that gives the ECU an accurate real-time picture of what the chassis is doing using minimal software. Incorporating a Bosch IMU and the latest evolution of Kawasaki’s proprietary dynamic modeling software, the ZX-10R’s electronic management technology helps assist racers experience the ZX-10R’s full potential, on the track.

Inertial Measurement Unit (IMU)(KP)
• The IMU measures inertia along 5 axes: acceleration along longitudinal, transverse and vertical axes; roll rate; and pitch rate. The yaw rate is calculated by the ECU using Kawasaki’s patented software to provide six-axis chassis attitude input of lean angle and acceleration/deceleration force for more precise management of the electronic riding aids.
• Utilizing the IMU, S-KTRC incorporates abundant feedback to help maximize acceleration when exiting corners on the track.
• Due to the information from the IMU, the Launch Control system on the ZX-10R is highly advanced.
• The IMU enables KIBS-equipped models to utilize the Corner Management function.
• Unlike competitors’ systems that have pre-set limits, Kawasaki’s proprietary race-developed software enables the ZX-10R to have a dynamic system that has a higher level of chassis awareness and adapts to changing track conditions such as vehicle attitude, pavement conditions and tires.

Sport-Kawasaki Traction Control (S-KTRC)(KP)
• With precise management due to the IMU, racers can choose from five modes, plus OFF, to set S-KTRC feeling for specific track conditions and riding preferences. The two highest modes provide
minimal intrusion to enhance high-level racers’ experiences on the track.

• S-KTRC helps maximize acceleration out of corners on the track by allowing power slides and power lifts as long as forward acceleration is maintained. The system distinguishes between torque lift, which is smooth and allowed if acceptable acceleration is maintained, and sudden undesirable lift that triggers system intervention.
• Using complex analysis, the system calculates when traction conditions are about to become unfavorable and acts to help maintain optimal traction to enhance acceleration. By making small
changes quickly, power spikes are minimized for ultra-smooth operation and quicker lap times on the track.

KAWASAKI NEXT-LEVEL ELECTRONICS FOR THE TRACK
Kawasaki Launch Control Mode (KLCM)(KP)
• Designed to assist the racer by optimizing acceleration when launching from a standstill on the track, KLCM electronically controls engine output to optimize acceleration on the starts, help prevent wheelspin and minimize front end lift.
• Riders can choose from three modes, each offering a progressively greater level of intrusion. Each mode allows the racer to launch from a stop with the throttle held open.

Power Mode
• Allows riders to choose from three power options:
Full power operation
Mid power – Variable operation depending on throttle position
Low power – limited to approximately 50-60% of full power
• Works independently from S-KTRC.

Corner Management Function
• Corner Management Function uses both KIBS and S-KTRC to assist racers trace their intended line through a corner on the track by suppressing the tendency for the bike to stand up while braking in a turn. The IMU helps the system maintain optimum hydraulic pressure based on the bike’s lean and pitch angles.

Available Kawasaki Intelligent anti-lock Brake System (KIBS)(KP)
• High-precision system with smooth feedback for added braking confidence.
• The engine ECU communicates with the ABS ECU (which monitors wheel speed and front caliper hydraulic pressure) to regulate brake pressure. The high-precision control provides a more consistent
lever feel than conventional ABS systems. • Back torque limiting clutch system suppresses ABS function during downshifts for optimum performance.

Electronic Steering Damper (ESD)
• Settings match chassis dimensions and track handling characteristics.
• Jointly developed with Öhlins, steering damping characteristics are changed electronically according to vehicle speed and the degree of acceleration or deceleration. At low speeds, the settings were chosen so that damping does not interfere with the bike’s intrinsic lightweight handling. At higher speeds on the circuit, damping increases to help riders set the bike on the line
of their choosing. Using input from the rear wheel speed sensor (provided via the engine ECU) the electronic steering damper’s ECU identifies the vehicle’s speed as well as the rate the bike is accelerating or decelerating to fine tune damping.
• The enhanced feeling offered by the electronic steering damper allows riders to relax more, contributing to reduced rider fatigue.
• During strong acceleration or deceleration, damping is increased to enhance performance.
• Features Öhlins’ special twin-tube design for consistent damping performance, even under harsh track conditions, plus superb kickback absorption.
• The damper’s high precision construction and use of an integrated clamp help minimize friction as the damper piston moves so that initial motion is very smooth. With development input from Kawasaki’s championship-winning World Superbike team, the ZX-10R engine has superb horsepower. While it maintains a very linear power delivery to help the rider open the throttle early when exiting a corner on the track, low-to-mid range power is exceptional for quick acceleration.
• Light crankshaft and optimized moment of inertia for quick engine response and light handling to help make the bike turn-in quickly.
• Light pistons enhance engine response while a Teflon resin coating helps reduce friction.
• Long-reach spark plugs from the Ninja H2 allow large coolant passages in the cylinder head for optimum cooling performance.

• Straight, wide intake and exhaust ports enhance top-end power characteristics.
• Lightweight titanium intake and exhaust valves reduce reciprocating weight.
• Compact valve train reduces cylinder head height.
• Camshafts are carved from forged chromoly billet, which is more than one-half pound lighter than cast cams. The cams and tappets are treated with soft nitriding to help prevent galling and seizing with the aggressive, high lift profiles.
• Single valve springs with oval cross sections are light and lower to reduce overall cylinder head height.

Ram Air Intake
• Ram air duct positioned close to front of the bike for optimum air box filling efficiency.
• Large 10-liter airbox helps boost engine response and low-mid range power for enhanced racetrack acceleration.
• Resonator chamber built in to frame spars to help reduce intake noise.

Digital Fuel Injection
• 47mm main electronic throttle valves (ETV) operate with high precision to help provide smooth engine response on the track. The simple system also enhances input to S-KTRC and accommodates the Kawasaki Launch Control and Kawasaki Engine Brake Control features.
• High speed 32-bit ECU provides precise engine management and is housed in an aluminum case for efficient heat dissipation.

Titanium Alloy Exhaust
• Titanium alloy provides better heat resistance than pure titanium so the exhaust system can be made thinner, and lighter, without sacrificing durability.
• Header pipe diameter and length very similar to race-use headers make it easy to increase circuit performance by adding competition-use only slip-on muffler.
• Large-volume pre-chamber with exhaust valve at exit is placed under the engine to centralize weight, reduce exhaust noise and help minimize muffler volume.
• Single, right-side muffler lowers the overall center of gravity and helps centralize mass.

6-Speed Cassette Transmission
• Non-contact, potentiometer-type sensor quick shifter to facilitate seamless acceleration.
• Gear ratios help provide strong acceleration for circuit use and contribute to smooth downshifts.
• Dry-film lubricant coating on certain transmission gears reduces friction so gears slide into place easily for quick, sure shifting.
• Thin clutch primary gear is light to contribute to the quick engine response.
• Cassette-style transmission facilitates quicker gear ratio changes to suit track conditions.
• Primary reduction ratio, final drive ratio and fourth through sixth gear ratios minimize rear end lift and squat during acceleration or deceleration, allowing greater freedom with suspension settings.
• A back-torque limiting clutch automatically disengages the clutch under hard braking and deceleration to help prevent rear wheel hop during corner entry on the track. Optional springs, spring retainers and shims are available to fine-tune the clutch for specific track conditions.

Aluminum Twin Spar Backbone Frame
• Optimized geometry for sharp circuit handling.
• Steering head pipe position helps weight the front end for optimum feel, feedback and flickability.
• All-cast aluminum construction requires fewer pieces to reduce weight and welds.
• Direct line from head pipe to swingarm pivot for great cornering performance.
• The engine is mounted strategically in the frame to raise the center of gravity and place more weight on the front end. Combined with the rake angle, it helps make the ZX-10R highly flickable side-to-side for great cornering performance.

ALUMINUM FRAME

Jointly developed with Showa In the World Superbike Championship, the Balance Free Fork (BFF) is complemented by Showa’s latest rear shock, the Balance Free Rear Cushion (BFRC), to provide track riders the best possible performance.

Showa Balance Free Fork (BFF)(KP)
• The damping valves are located outside the fork cylinder so that the hydraulic circuit does not generate the pressure balance fluctuations that typically occur in conventional dampers.
• Compression and rebound damping are generated, and adjusted, completely independently from each other. By placing the valving in a damping force chamber, the whole surface of the fork piston can act on the oil, stabilizing internal pressure which results in a more compliant fork.
• External compression chamber contains pressurized nitrogen that applies force to the oil, helping to maintain balanced pressure inside the fork tube.
• Provides high ride comfort and performance under braking while enhancing front-end feel.
• Fully adjustable preload and compression and rebound damping enables riders to fine tune the suspension for a wide variety of conditions. Showa BFRC-Lite (Balance Free Rear Cushion) Shock Absorber(KP)
• Like the fork, damping valves are located outside the shock cylinder so that the hydraulic circuit does not generate the pressure balance fluctuations that typically occur in conventional dampers.
• By placing the valving in a damping force chamber, the whole surface of the shock piston can act on the oil, stabilizing internal pressure which results in a more compliant shock.
• Provides high ride comfort and traction and reduces weight.
• Fully adjustable compression and rebound damping plus threaded preload enables riders to fine tune the suspension for a wide variety of conditions. Horizontal Back-link Rear Suspension(KP)
• Linkage ratios deliver a linear feel and offer a wide adjustment range, so that setting changes are easy for the rider to feel.
• The swingarm has high rigidity to contribute to the nimble handling and help put weight to the front.
• The linkage is placed atop swingarm to make room for the exhaust pre-chamber for better mass centralization.
• Rear shock is further away from the exhaust so that its operation will not be affected by exhaust heat.

Race-Spec Brembo Brakes (also available with Kawasaki Intelligent anti-lock Brake System(KP) (KIBS)
• Similar system to that used on the Ninja H2 and the World Superbike race machine.
• Radial mounted 4-piston front brake calipers.
• Front brakes feature Brembo M50 cast monoblock calipers with four opposed 30mm pistons that clamp on huge 330mm Brembo discs for superb braking force. The outer edges of the discs have grooves down the center of the outer edges to help dissipate heat.
• Brembo radial pump master cylinder and reservoir are calibrated to require very little lever movement to achieve strong front brake force.
• Stainless steel braided brake lines contribute to direct feel.
• Available KIBS high-precision anti-lock brake system provides smooth feedback and minimal lever movement for added braking confidence on the circuit.

Aero/Styling
• Upper cowl resembles the factory World Superbike machine, reduces drag and provides optimum wind deflection so that the racer can change position more smoothly at track speeds.
• Strategically-placed vents in the upper cowl help prevent negative pressure build-up in cockpit to reduce helmet buffeting.
• Ninja H2-design front fender helps direct airflow to the radiator.
• Taillight design provides an aggressive image. Multi-mode Instrumentation
• Utilizes a race-type, highly-visible LED-backlit bargraph tachometer strategically placed at the top of the instrument panel.
