Jun 21, 2013 Kawasaki has updated both the KX250F and (less so) the KX450F for 2014. The motocross models will hit showroom floor in mid-July, when Kawasaki will announce pricing.
Launch Control is a first for a 250-class motocross bike. The system maximizes available traction, increasing a rider’s ability to get good starts.
The KX250F’s technology also includes a plug-and-play adjustable ECU, a Separate Function Fork (SFF), new motor mounts, revised suspension tuning and an upgraded transmission.
- The high-tensile steel front-engine mount plates are 29 percent thinner than last year’s steel plates and offer a better mix of chassis rigidity, improved feedback and front-end grip.
- The KX250F’s transmission gears feature four dogs instead of three, for enhanced shift smoothness.
- The shift-fork grooves are more direct to enhance feel at the shift lever.
- The counter-shaft and sprocket retainer design now uses a nut and washer
instead of a clip, for a more positive sprocket-to-countershaft
interface and simplified sprocket swaps.
- An upgraded crankcase oil jet delivers a stream of oil to the underside of the piston, for enhanced cooling.
- Revised throttle body tuning improves airflow from a closed-throttle, for a smoother idle and enhanced low-end response.
- Revised piston tuning in the left fork leg enhances damping performance through the initial and midstroke.
- Revised rear shock settings provide a more comfortable “baseline” for a wide range of riders.
- Grips feature shorter barrels and are made from a softer material to enhance rider comfort.
