Nice design to get just the right height and backset on your Grom, CRF50, NSF100, or NSR50. Also fits most import pitbikes on the market. 7 position mount and ability to rotate the peg separate from the positioning make these super handy. About 1 inch rise over stock adds cornering clearance while not making for an uncomfortable ride. Billet aluminum construction and folding design ensure they'll last a long time.
