A huge inlet in the airbox design adds to the feeling of power. The internal design of the slim muffler further improves power delivery, and the exhaust system features a short header. The muffler is placed under the engine to help centralize weight and lower the center of gravity. The Kawasaki Air Management System (KP) (KAMS) radiator fan cover helps direct hot engine air away from the rider and down.

The compact parallel twin engine maintains the bike’s small and agile dimensions. The triangular crank and transmission shaft layout makes the engine very small from front to back. A semi-dry sump (KP) oil system reduces the overall engine height. The narrow pitch of chrome composite (KP) plated aluminum cylinders helps reduce the engine width. A 180-degree crankshaft plus balance shaft ensures incredibly smooth engine operation.

Digital Fuel Injection

Fuel injection settings support quick engine revs while offering a smooth, low-end response. The 36 mm diameter throttle body features sub-throttle valves for maximum efficiency and rideability and uses fine atomizing injectors to further improve engine response and low-to-mid range power.

The ECU regulates the sub-throttles behind the main throttle valves, giving the EFI system a more precise throttle response like a constant-speed carburetor. Exhaust catalyst combined with precise fuel injection dramatically reduces emissions. It is easy to start and warm up thanks to the automatic high-speed idle mechanism.

Assist & Slipper Clutch

To use shorter and lighter clutch springs for a lighter feel on the lever, the clutch is pressed with acceleration (assist function) using the rotational forces of the new clutch hub and pressure plate. When the back torque is excessive, such as when a gear is selected too low, the slipper function enables some clutch slippage to help prevent rear-wheel hop and engine lockup.

6-Speed Transmission

The cassette-style transmission shift drum and shaft are tightly aligned. It has a linkage-type gear change mechanism for a positive shift feel and touch. It also features a positive, neutral finder, a user-friendly feature unique to Kawasaki.


The high-tensile steel trellis frame has optimized dimensions and wall thickness, reducing frame weight and significantly contributing to ultra-light handling. Frame components follow the ideal pipeline to make the frame lines as straight as possible. Their angles were as small as possible when bending was necessary, resulting in a great design dissipating stress. Three-point rigidly attached engine and footpeg stays are used as stress members to contribute to weight reduction.

The Ninja ZX-10R‘s horizontal back-link progressive suspension technology maximizes ride comfort, sport riding capabilities, and balance. The hollow press construction of the gullwing swingarm helps keep it light. The rear shock is further away from the exhaust, so the exhaust heat does not affect its function. The linkage is positioned above the swingarm and aids make room for the under-engine muffler for greater mass centralization.

41mm Front Fork

To enhance the look of 2023 Kawasaki Ninja 650 Sports Bike, the upper triple clamp has fashion-reinforcing ribs on the upper surface. Brake discs with three-petal design Nissin brake calipers give a sporty vibe while offering excellent brake feel and control. Large 27mm pistons and dual 300mm petal discs through the front brake calipers provide excellent braking feel. The petal shape provides good cooling and resistance to warping.

Wheels and Tires

The sporty five-spoke wheel design looks light and agile. Dunlop Sportmax Roadsport 2-made tires help with light handling.

Confidence-Inspiring Cockpit

The separate clip-on handlebar is slightly forward above the upper triple clamp for an aggressive sport-riding stance. To help maintain comfort, the soles of the feet are placed down and forward, opening the leg position. The fuel tank is low on the chassis, and its slim design helps it reach the ground more for added rider confidence.

The seat is low and thin at the front to make it easier for the rider to keep both feet on the ground at a stop. The resin fuel cap design eliminates the need for mounting bolts for a sleeker look. Clutch and brake levers are 5-way adjustable to fit various hand sizes and improve handling and comfort.
