The 2007 CRF450R received a ton of modifications and upgrades, taking the top-class MX performance to an even higher standard. For 2007, the engine got a multi-map CDI, an increased upper rev limit, a lighter counterbalancer and drive gears and a better clutch.
A lightweight Honda Progressive Steering Damper (HPSD) was added for more precise steering, while the rear shock valving was matched to the front dampers. Using advanced design and light materials, the 2007 CRF450R remained a slim and nimble machine, a dependable ride for the victory-focused riders who want to push their limits even further.
