The new downdraft-style intake layout, new intake valves, and new piston deliver increased cylinder-filling efficiency and improved combustion for increased peak performance.

In addition to increased performance, a racer-friendly power delivery was achieved by increasing the moment of inertia in the magneto rotor. Riders will also benefit from lighter clutch operation thanks to the new clutch pushrod.

New advanced ignition timing was developed to complement the engine changes made to the KX™250. Thanks to a new 100mm longer exhaust header pipe, riders can enjoy increased low-mid torque.

Based on feedback from Kawasaki’s factory racing efforts, the transmission's first gear was lengthened to make it easier to use in a greater number of situations. Second gear ratio was also fine-tuned to offer a smooth transition from first to third gear.

For increased strength, the connecting rod big-end bearing crush height was increased and the main holding circuit relay was revised.

Electric start makes for quick and easy engine starting at the push of a button.

Contributing to the race-winning engine characteristics, the digital fuel injection system of the KX™250 features a coupler package that has set the industry standard.

Each KX™250 motorcycle comes standard with three different couplers, easily allowing riders to select pre-programmed fuel injection and ignition mapping to suit their riding style or track conditions. The four-pin DFI® couplers select maps that are designed for standard, hard or soft terrain settings. Changing the engine map is as simple as connecting the coupler cap of choice.

For riders looking to fine-tune their ECU settings, the KX™ FI Calibration Kit (handheld) is offered as a Kawasaki Genuine Accessory (sold separately) and provides access to the fully programmable ECU.

Used by the factory race teams, the handheld device eliminates the need for a trackside laptop and gives riders the ability to create custom maps for precise adjustment of fuel and ignition settings. The user-friendly device can store up to seven preset maps and is PC-compatible.

The Kawasaki Launch Control Mode (KLCM) system of the KX™250 motorcycle is a major advantage and favorite for riders who are focused on getting to the first turn ahead of their competition.

The push-button activation retards ignition timing in first and second gear, helping maximize traction on slippery surfaces like concrete starting pads and puts the bike’s potent power to the ground. Once the rider shifts into third gear, normal ignition mapping immediately resumes and full power is restored.

A high-performance KYB 48mm inverted coil-spring fork handles suspension duties up front while the large diameter inner tubes and large 25mm damping pistons deliver smooth action and firm damping.

For 2023, the front and rear suspension settings have been revised contributing to improved cornering -- a more planted feel upon corner entry and improved performance at the exit of the corner for stronger acceleration.

New Dunlop MX33 tires offer increased traction to match the engine’s increased power. Stay grounded with a new wider 110/90-19 rear tire that contributes to a greater planted feeling and increased rear wheel traction.

An oversized 270mm front disc contributes to strong front brake force and a high level of control and the 240mm diameter rear disc offers performance for controllability and total riding confidence.

A factory-style aluminum Renthal® Fatbar® handlebar with 4-way adjustable mounts comes standard. With grips positioned low and close to the body, riders can shift weight forward more easily to improve front-wheel traction and increase front traction feel, to ride more confidently at the limit.

Slim radiator shrouds are positioned close to the frame to facilitate grip for the rider's legs.

The top of the fuel tank features a design that allows a flat progression from the seat to the tank. The result is great freedom of movement when changing riding position. The seat features a slip-resistant top surface and smooth sides for an excellent balance of grip and mobility.

In-mold graphics on the shrouds result in an ultra-smooth surface, greatly extending the life of the race-style graphics.
