The perennial bike of choice of the enthusiast press and racers alike, the CRF450R returns in 2010 to take its rightful place far ahead of the competition. Introduced as an all-new lighter bike with fuel injection in 2009, the CRF450R earned overwhelming praise, winning a host of comparison tests and best-in-class awards. Now, enhancements to the EFI electronic control module and automatic decompression system make the 2010 CRF450R easier to start and also give it better throttle control than ever before. Add in suspension refinements for superior handling, durability and improved stroke compliance front and rear, and it’s easy to see why the CRF450R has been–and also will remain–at the head of the class.2010_honda_crf450r
