We took our industry-first, all-aluminum frame and added features to inspire any motocross rider. Ready to race right out of the box, competitive advantage comes standard on the DS 450 X mx. Like Kashima-coated KYB HPG front and rear shocks. Or ITP QuadCross MX PRO tires on black aluminum ITP T-9 wheels. Aluminum nerf bars. A raised (+1in.) steering stem with anti-vibe mounts. The X mx was built from the lessons learned and success achieved from racing multiple pro series.
