Slimmer rider interface
More compact bodywork and a shorter fuel tank result in a slimmer design allowing a more natural riding position, making it easier for riders to go fast. The flat seat makes for smooth changes to riding position, and new seat padding helps the seat keep its shape longer.
All-aluminium perimeter frame
The KX250F's slim aluminium perimeter frame is a lightweight construction composed of forged, extruded and cast parts. For 2013 the main tubes are narrower for improved ergonomics. The stiffness balance is also improved for superior cornering performance and better traction.
Race-spec rear suspension
Race-spec Uni-Trak rear suspension system features a rear shock unit with dual compression adjustability, allowing precise, independent adjustment of high-speed and low-speed damping.
Less rigid tie rod arms offer smoother action and improved bottoming resistance, which (along with the new frame's revised rigidity) contributes to greater rear wheel traction.
Latest front suspension: SFF Type 2
The Separate Function front Fork (SFF) separates damping and shock absorption duties: its damping assembly is in the left fork tube and a single spring is located in the right. This design reduces friction for smoother operation. A larger diameter damper delivers improved damping performance, and the added space makes it easy to add a preload adjuster, making for quick suspension adjustments. For 2013 a SFF Type 2 fork is used which features idealised internal construction for increased rigidity, more planted feel, greater bottoming resistance and improved all-around performance. The new KX250 is the only machine in its class to feature titanium-coated inner tubes, resulting in less friction and better protection from flying rocks.
New factory-style graphics, black alumite rims, black fork guards, blue alumite finish on the suspension adjusters, and a blue finish on some of the engine trim give the KX250F the aggressive looks to match its highly tuned performance.
Among the KX250F's numerous factory-style components are its front and rear petal disc brakes. In addition to helping reduce unsprung weight, the wave shapes of the petal discs help clean the brake pads for more efficient braking performance. For 2013, pushrods are used at the master cylinders for improved braking feel.
