Petal Disc Brakes
Stopping power! Petal brake disc with special wave shapes help keep pads cleaner so you get maximum braking power all moto long.
Front Suspension
Holding the inside line is easy with the new 48 mm Kayaba AOS (Air-Oil-Separate) fork. Fully adjustable, it lets you tune the suspension to suit track conditions.
Frame & Rear Suspension
Go for it! A perfect combination of forgings, castings and extrusions gives the KX450F's new perimeter aluminium alloy frame balanced flex and high-flying lightness. New linkage ratios maximise rear wheel traction, and dual-speed compression adjustment makes the shock easy to tune.
