KX250 2025

Race to victory on the bike built for winning. The KX250 motorcycle is the most competitive racing package yet, with an improved chassis, an updated engine, and all-new Power Mode Selection and Kawasaki TRaction Control (KTRC). Plus, cutting-edge technology like ERGO-FIT components and RIDEOLOGY THE APP KX offer maximum adjustability, so you can find your unique winning style. Be the fastest in the pack. Be the next champion on the KX250.

Factory-Style Engine Components & Tuning

The base factors that have made the KX250 engine a standout performer in its class—finger-follower valve actuation, a downdraft style intake, and dual injectors—are complemented by revised intake and exhaust layout and a single-shaft primary balancer, for an all-around stronger package with enhanced control better capable of challenging for race results.

Factory-Style Chassis Components & Tuning

The KX250’s new frame is based on that of the 2024 KX450, and updates for 2025 to suit the new intake and exhaust layout help to deliver improved handling. Smooth bodywork is designed to facilitate rider movement and control, and fine-tuned suspension and brake components further contribute to the KX250’s light, agile handling. New ODI Lock-On grips and a quick-release side cover add convenience.

Advanced Tech at Your Fingertips

Complementing an updated Launch Control Mode, the new KX250 and KX250X offer Power Mode selection and Kawasaki Traction Control at the push of a button. And with smartphone connectivity, riders can adjust engine maps right from their smartphones.

Single-Shaft Primary Balancer

A single-shaft primary engine balancer contributes to smoother power delivery and reduced vibration, which improves control, especially when exiting slower-speed corners.

Enhanced Throttle Control

Complementing the significantly increased low-end torque and the smoother power delivery, throttle response is more linear, delivering lag-free power in proportion to how much the throttle grip is twisted. This greatly facilitates control, enabling smooth acceleration on challenging or low-traction surfaces, helping riders push the limits more confidently, and reducing rider fatigue so that they can more easily maintain their pace for the duration of the race.

Power Modes

Using the Mode (M) button on the left handlebar, riders can quickly and easily switch between two engine maps (Normal, Aggressive) provided in the ECU.

Kawasaki TRaction Control (KTRC)

Using the Traction (T) button on the left handlebar, riders can quickly and easily select from two levels (Weak, Strong) of traction control to suit conditions and preference. Riders may also elect to turn the system off.

Holeshot Advantage: Launch Control Mode

Factory-style launch control system increases the chance of getting a good start by helping riders maximize traction when starting on a low-traction surface.

Race-Ready Suspension

High-performance Showa Ø 49 mm inverted coil-spring fork and New Uni Trak rear suspension offer race-ready suspension performance and adjustability to let riders tune their settings to suit conditions.

Even Stronger Engine with Symmetrically Aligned Intake & Exhaust

A symmetrically aligned intake and exhaust deliver a strong overrun and smooth low-rpm torque characteristics. Redesigned intake offers a much straighter route for air-fuel mix to enter the cylinder, while a centrally positioned exhaust port lines up with the intake for high airflow efficiency—both contributing to increased performance. The optimized downdraft intake also adds to low-end performance.

Electric Start

Being able to restart an engine quickly after a spill can mean the difference between keeping your lead or having to fight your way back through the pack. Electric start makes restarting the engine as easy as pushing a button.
