The 2027 Kawasaki KX450FX is Kawasaki's flagship 450cc-class cross-country machine, carrying motocross-bred performance into the toughest off-road conditions with a 449 cc 4-stroke engine and electric start that gains a more aggressive power feel at mid-to-high rpm from revised intake, exhaust, and FI settings, paired with a coned disc-spring hydraulic clutch for direct, consistent feel. It's built around a new aluminium perimeter frame with a longer wheelbase for enhanced traction and high-speed stability, matched to a Showa 49 mm inverted coil-spring fork and New Uni-Trak rear suspension tuned with cross-country-specific spring rates and damping, plus a complete Brembo brake system for maximum stopping power on varied terrain. Cross-country-ready hardware includes 21"/18" wheels with Dunlop AT81 enduro tyres, a 7.5 L large-capacity fuel tank, skid plate, hand guards, and side stand, while rider tech spans handlebar-mounted Power Mode selection, Kawasaki Traction Control (KTRC), and an updated Launch Control Mode, all enhanced by smartphone connectivity via GPS and RIDEOLOGY THE APP KX2 — rounded out by new athletic bodywork, ERGO-FIT adjustable ergonomics, ODI Lock-On grips, and front/rear accessory power connectors.
