Just like its bigger sibling, the 2005 CRF250R has received a lot of upgrades in the technical areas. The engine got a new head porting, with new camshaft profiles, a new mapping which delivers more torque, a new side-electrode spark plug, lighter covers, stiffer clutch springs, and upgraded shift drum, forks and shafts for more precise shifting.
The exhaust has also been redesigned for better mass centralization, and the bike's suspensions have also been reworked. As for the rest, the 2005 CRF250R remains the same brawny, dependable, winning motocross machine, loaded with race-grade parts and ready to deliver holeshot after holeshot on the track.
