Frame Kit - Perimeter +2"/+5" w/Supercomp Adj. Swingarm / XR/CRF50

The BBR Perimeter Frame Kit is the ultimate upgrade for your XR/CRF50. An engineering masterpiece with the results to back it up. This frame has won numerous 50cc titles in America and around the world: Langtown, White Bros. World Championship, Screwy-Dilla, Sweet Bud, Vegas MiniMoto SX, Texas MiniMoto, Northwest Indoor Championship, Australia National Championship, and many more. The unique frame and swingarm design provides superior handling and eliminates the motor as a stress member of the frame. Broken motor cases and twitchy handling are a thing of the past! 100% engineered, machined, welded, heat-treated and tested in the USA. No other frame on the market even comes close.
