The KX450F base package provides an excellent platform for experienced racers to win races in the top classes. Design of the highly rigid aluminium frame, suspension components and settings focused on delivering superb high-speed stability – especially in straight lines – to enable race-experienced riders to ride full out. And to deliver holeshotwinning performance – a key factor that can mean the difference between running up front and winning, or getting stuck mid-pack – chassis geometry and the hard-hitting 4-stroke engine’s wide powerband were designed to maximise rear wheel traction. The combination is a proven race-winner, with Kawasaki racers regular podium finisher.
