Kawasaki has launched its 2013 motocross collection, with the new KX250F and KX450F. Both bikes come with updated styling and improved performance.
The KX450F comes with a new ‘pneumatic spring fork’ (PSF), the first on a production motocross, which replaces conventional fork springs with pressurised air, Kawasaki claims, to deliver firmer suspension and less resistance.
Power is up across the whole rev range, thanks to a new piston design and revised ECU, plus there’s now launch control mode, petal disc brakes and adjustable ergonomics with four handlebar and two foot peg positions.
The KX250F comes with a ‘separate function front fork’ (SFF) ‘type 2’ which has a spring in one fork and packs damping into the other; along with petal brake discs, and dual injectors and a straighter intake which is again claimed to improve performance at high rpm.
Both bikes have a new DFI plug-and-play data setting engine, which allows access to three engine maps: standard, soft and hard, reprogrammed with a KX FI calibration kit. There is also new, slimmer frame and bodywork.
