KFX450R KFX 450r Review
by Nick Harris on September 3rd, 2007Kawasaki KFX450R ATV - Kawasaki brings a heavy dose of racing technology to the 2008 KFX450R ATV. The Kawasaki KFX450R is ready to race right out of the crate! Of course you may want to bolt on some high performance KFX450R parts to make it even better but you don’t have to break the piggy bank to do it.
The KFX 450 introduces a 32-bit digital fuel injection system to help the KFX450R’s engine produce more torque in the low and medium rpm ranges. Expect outstanding hole-shot acceleration and don’t let go of the grips. Other KFX450R features include a lightweight titanium exhaust header pipe and a durable forged piston and an all aluminum frame.
Kawasaki’s KFX450R model also has the only reverse gear in its class. If you happen to get stuck at the start of a race or run straight into a wall your race doesn’t need to be over, a quick reverse and you’re back in the race. The KFX450R was also designed to take high speed cornering by making it sit low to the ground and eliminate roll tendencies.
