True Street-Legal Dirt Bike
The CRF450RL uses the CRF450R motocrosser as a starting point, then adds everything required to make it fully road-worthy. From the CRF450R base, the frame was made slightly wider to allow for the 6-speed transmission, the engine was tuned for smoother power delivery, and the suspension and brakes were modified to make the bike more user friendly on tight trails and on the road.
