Swingarms are constructed for the rider that wants the most out of their swingarm. Designed for TT and Flat track applications. These swingarms are lightweight and super strong. Swingarms are constructed from 1-3/8" 0.095" wall 4130 chromoly tubing or 1"x 2" rectangle tubing and by request can have added gussets to make them more rigid to hold up to the demands of the track. All swingarms will not come with chain slider mounts for the front pivot unless one is purchased or special instructions are received.
