Kawasaki KFX 450R Specs, Weight and Top Speed

Kawasaki KFX 450R In-Depth Guide

Kawasaki infused a heavy dose of racing technology into the 2008 Kawasaki KFX 450R ATV. The Kawasaki KFX 450R is ready to race right out of the crate! Of course you may want to bolt on some high performance KFX 450R parts to make it even better but you don’t have to break the piggy bank to do it. Seat height is 30.9 inches and top speed is 85 MPH.

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 don’t let go of the grips. Other KFX450R features include a lightweight titanium exhaust header pipe and a durable forged piston 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.

This 2010 Kawasaki KFX 450R is SUPER CLEAN and in immaculate condition ready for some serious ATV mudding! Actually it’s so clean I would hesitate to get into the mud, maybe for a minute anyway.

Special features include the 449cc 4-stroke fuel injected engine with 5-speed + reverse manual transmission. The rest of the quad is essentially stock but it’s so clean you could eat off it. I ran the VIN number and it checks out as ready to be a project build candidate.

Overall this KFX450r has a lot of great qualities, I found it in Arlington Texas with a $5,500 asking price.
