For 2008 the SXV 450 received a reworked rear end, with revised shock calibration and a new linkage giving more progressive damping, plus new fork settings for better high-speed stability. The choke moved to a knob on the airbox, the air filter gained racing-derived foam, and new race colours were applied. Motorcyclist reported the 2009 bike carried over unchanged.
