The Mongoose is specifically designed for the 50 cc KTM Bikes. This fully CNC machined clutch is made from state of the art materials to provide the racer with superior performance reliability and longevity. The Gator-Grip friction discs are the latest proprietary technology capable of handling the higher temperatures created by the stall speeds of the 50cc Stock and Modified Bikes. This combination provides a clutch that is capable of transferring the torque to the rear wheel for that Hole Shot!
