1-1/8" (28.6 mm) diameter, double-walled aluminum alloy handlebar. Immense strength, very good resilience and a virtual guarantee against fatigue failure. Unlikely to bend except in severe crashes. Specifically designed for MX and Supercross. Bar pad colors may vary from shown. Fits existing handlebar clamps and allows for use of 1-1/8" big bars. "Universal Mounts" bolt on top of stock 7/8" bar mounts, and adds 1/4" rise. "Rubber Mounts" replace the stock bar mounts on CR/CRF, KX/KXF and RMZ models.
