ASV introduces the Rotator Clamp, a revolutionary new concept that protects your lever and master cylinder from vertical impact damage. It replaces the stock half clamp on the back of your brake master cylinder. When your perch / master cylinder does rotate out of harms 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 / brake 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.
