450 SX-F 2012 - OVERVIEW

When it comes to pure power, there is still nothing to replace displacement. The only problem is applying the power to the ground. The 450 SX-F's high-quality chassis allows advanced riders to convert the brutal power of the innovative DOHC four-stroke engine into controllable traction, even on the toughest MX tracks. With an even more robust clutch, the 450 SX-F is still a real ace in the MX1 class.
