The 2014 Kawasaki KX250F comes with a new Launch Control system, a plug-and-play adjustable ECU, Separate Function Fork (SFF), new motor mounts, revised suspension tuning and an upgraded transmission. The new launch control system is the first of its kind on a 250cc motocross. Launch Control has maximum effect within the first few seconds of releasing the clutch. This high-tech system is particularly effective when chasing the hole-shot from concrete starting pads and other slippery surfaces than on previous model, or comparing with other 250cc motocross bike. Along with all that advanced technology and race-proven performance, the it also offers more adjust-ability than its competition, allowing the rider to fine-tune the motor and suspension capabilities to meet the sport’s rigorous demands like no other bike in its class.
The 2014 Kawasaki KX250F frame features narrow main spars for excellent ergonomics that offer superior freedom of movement in the saddle. New high-tensile steel front engine mount plates are 29% thinner than previous year’s steel plates. While the DFI® system features dual injectors that pack a one-two punch, delivering a second dose of fuel on acceleration to maximize the high-rpm power and over-rev capabilities. It comes with three pre-programmed ignition maps which are easily select-able without the use of a laptop computer or any other electronic devices. Its performance is also enhanced via the new exhaust system, which uses a short header with a resonator chamber to help enhance low-end power and reduce noise. A KX450F-style muffler is short but features a large cross section to help centralize mass while meeting sound requirements.

2014 Kawasaki KX250F Features
Engine and Transmission – 249cc, liquid-cooled, four-stroke, four-valve, single-cylinder DOHC engine delivers hard-hitting power across the RPM range. Launch Control is activated by pushing a button on the left handlebar while stopped, in neutral, first or second gear. Retards ignition timing in first and second gears, giving the greatest effect within the first few seconds of releasing the clutch. Progressive throttle linkage for sharp and precise throttle response across entire RPM range. Simple and efficient system, no battery, fuses or relays, it offers easy engine starting and it helps prevent engine hesitation after landing from jumps and other high-impact situations. Transmission gears feature four dogs instead of three, for enhanced shift smoothness, shift-fork grooves are more-direct to enhance feel at the shift lever. The clutch cable holder is integrated with the crankcase for accurate feel at the clutch lever, while scavenge oil filter screen can be accessed without splitting the crankcases, facilitating easier maintenance.
Chassis and Suspension – Slim and lightweight aluminum perimeter frame helps provide excellent ergonomics and handling, and center of gravity and key dimensions such as swing-arm pivot, output sprocket and rear axle locations designed to increase forward drive with minimal rear-end squat. Bodywork components offer the rider a slim interface, making it easy for racers to feel comfortable and go fast. Frame is wider at the ankles to offer better grip and narrows near the bend below the seat to allow a slim riding position. 48mm Separate Function Fork (SFF) delivers firm damping response and increased ride comfort and the SFF design separates springing and damping functions for less weight, better performance, less stiction and easier adjust-ability compared to traditional forks. Super-hard titanium coating on the outer surface of the inner fork tubes reduces stiction and improves suspension action while also helping prevent scratches and tube damage. Rear shock features dual compression adjust-ability, allowing high-speed and low-speed damping to be tuned separately. It features Kashima Coat on the inside cylinder wall for reduced friction and smoother suspension action. Uni-Trak® rear suspension linkage system mounts the suspension arm below the swingarm, allowing more rear suspension stroke and precise tuning. Front and rear petal brake discs help reduce unsprung weight, and the wave shape helps clean the brake pads for more efficient stopping performance on 2014 Kawasaki KX250F.
