Surge S Front Designed for trail riding enthusiasts and motocross racing weekend warriors, the Surge S is built to perform and constructed to last. The Surge S excels in any soft terrain. Its self-cleaning knobs grab all the traction you can handle, and the front keeps it on lock around berms and through the narrowest single-track trails in the woods.
