Used Kawasaki KX450 for sale
The Kawasaki KX450 is a 450cc four stroke motocross bike, built for the track and sold on hours rather than kilometres.
8 Kawasaki KX450s are listed on MWMX right now (2019 to 2024 models), asking $5,000 to $10,000, most around $7,000. Every listing shows the hours, photos and where the bike is, and you can message the seller or make an offer without an account.
A Kawasaki KX450 is a race four stroke, so hours matter more than years: ask when the valves were last checked and the top end last done (60 to 100 hours is a normal rebuild interval on a hard raced one), listen for valve or clutch noise on a cold start, and look for a bent subframe, stripped threads and a sprocket with hooked teeth. Ask for the service history (members log theirs in the MWMX Digital Garage and it shows on the listing), look at the hours against the price, and check the frame and swingarm for cracks, the fork seals for weeping and the linkage and steering head bearings for play.
