The Kawasaki KX450F is the most powerful Japanese 450cc motocross bike in production. The 450cc motocross division has changed this past year with a full-force jump into the fuel-injection technology, and the Kawasaki KX450F is a major player. Big and burly, the Kawasaki KX450F is known as a beast of a machine in a class already filled with brutes.
Although it looks identical to the ’09 machine, the 2010 KX450F employs engine and chassis changes aimed at making the bike easier to ride.
Introduced in 2006, the Kawasaki KX450F has been winning races right from the start. James Stewart piloted the KX450F to a FIM World Supercross and AMA Supercross title in 2007. He then swept the 2008 AMA Motocross Nationals with a perfect 24-for-24 season thanks to supreme skill and the competent KX450F.
The 2009 model is the second-generation Kawasaki KX450F, so in addition to the 43mm Keihin throttle body fuel injection with aluminum fuel pump, the KX450F also received updates to the motor’s top end and crankshaft, a slimmer chassis, updated Kayaba fork with DLC coating and a larger 50mm shock. Visually the Kawasaki KX450F is different also with new bodywork and graphics.
Tim Ferry and Ryan Villopoto are using the factory racers using the Kawasaki KX450F to assault the AMA Motocross and AMA Supercross division. Both riders should find great success outdoors where the KX450F can use all the power and speed provided by Kawasaki engineers. Our test riders picked the Kawasaki KX450F as the best 450 MX bike of the year.
