The new CRF450R features innovations forged by competition at the highest levels. An innovative Engine Mode Select button—an industry first for motocross machines—allows the rider to easily select one of three different EFI/ignition maps. A new fork with both high-/low-speed compression and rebound damping adjustment, larger front brake, new cylinder head, exhaust system, and revised settings for the Dual-Timing PGM-FI fuel injection elevate the CRF450R’s performance to a whole new level.
