Cycle World's 2006 MX Bike of the Year. Five years in a row. The CRF450R has won pretty much every honor thrown its way — and it has no plans of letting up. Which is why we've made it even lighter, more responsive and better handling than ever, retooling the cylinder head and intake valves, boosting the carb to 41mm, and adding a new brake lever linkage to improve stopping power, a new subframe and a Dunlop 742 FA front tire. Wicked, huh?
- Liquid cooled four-valve Unicam 449cc engine
- Auto decompression and hot restart system make starting easy in all conditions
