The CRF®450R rear shock linkage has changed so you get a softer start and a stiffer finish. It responds to small bumps better, but also resists bottoming over really big hits. At the front, new fork outer tubes are stiffer for better feedback and superior tracking in heavy dirt, mud, and sand sections. New springs and suspension settings front and rear keep the balance right and increase steering precision. The CRF®450R has wider, longer footpegs for better grip as well as premium Dunlop MX51 tires for superior traction.
