Being able to restart an engine quickly during a race 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.

A hydraulic clutch offers more direct feel and lighter lever action. Less play as the clutch heats up during heavy use results in more consistent feeling. The use of coned-disc springs contributes to lighter clutch actuation when the lever has been pulled in, and a wider clutch engagement range, which facilitates control (especially when half-clutching). New material for the clutch pushrod in 2023 (now an aluminium shaft with a steel cap) results in lighter clutch operation.

Lightweight and designed for the rigours of off-road riding, the ECU contains multiple programmable engine maps to offer riders an advantage on the racecourse. Using the provided DFI couplers, riders are able to easily switch from one to another of the three engine maps to suit riding conditions. The plug-and-play style system is quick, easy and stress-free. Each of the three maps can be reprogrammed using the optional KX FI Calibration Kit.

High-performance suspension comes directly from the KX250. Spring rates and damping settings optimised for the cross-country scene offer increased feedback, especially when riding on aggressive trails.

The KX250 brake package optimised for cross-country riding includes a large-diameter ø270 mm front disc complemented by a ø240 mm disc at the rear, KX450-type front master cylinder and KX250X-specific pads, delivering strong stopping power and a high level of control.

The narrow frame and minimalistic bodywork offer a slim riding position that facilitates control, and a smooth, flat rider interface.

A choice of four handlebar positions and two footpeg positions allows riders to tailor their riding position to suit body size and preference. Factory-style ø28.6 mm (1-1/8”) Renthal aluminium Fatbar is standard equipment. The thick handlebar helps reduce vibration and shocks transmitted to the rider and helps put the rider in a position that makes it easier to weight the front wheel.

Revised footpeg design as of 2023 is 5 mm wider (front-to-rear) and positioned 3 mm rearward, offering excellent grip, superb feel, and making it easier to weight the pegs.

KX factory-style skid plate and a convenient side stand are both standard equipment. The sturdy skid plate helps to protect the underside of the engine, and facilitates sliding over obstacles encountered on the trail, while the side stand comes in handy when stopping away from the paddock area.
