ASV introduces the Rotator Clamp, a revolutionary new concept that protects your lever and perch from vertical impact damage. It replaces the stock half clamp on the back of your clutch master cylinder. When your perch / master cylinder does rotate out of harm's way, you can simply move it back to the correct position with your hand! Features an integrated nylon sleeve between the clamp and the handlebar that allows the master cylinder / clutch lever to rotate upon impact. Protects the lever and master cylinder from damage, even when fully tightened. Adjust the lever position without tools. CNC-machined from 6061 billet aluminum. Fits ASV Clutch Perch and all bike-quad front brake master cylinders. Available with and without integrated Hot Start.
