2007 CRF450R

Overview: 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, eh?

2008 CRF450R

Overview: The experts are pretty much unanimous in hailing the CRF450R as the best MXer in its class. Holding that advantage, however, demands constant improvement, and the 2008 CRF450R is sharper than ever, with all-new works-style brake rotors, retooled frame geometry, and the revolutionary new Honda Progressive Steering Damper (HPSD). The gauntlet has been thrown. Again.
