ASV introduces the Rotator Clamp, a revolutionary new concept that protects your lever and perch or brake master cylinder from vertical impact damage. It replaces the stock half clamp on the back of your perch or brake master cylinder. The ASV Rotator Clamp features an integrated nylon sleeve between the clamp and your handlebar that allows your perch or master cylinder to rotate upon impact. It protects your lever and perch or master cylinder from damage, even when fully tightened. When your perch/master cylinder does rotate out of harms way, you can simply move it back to the correct position with your hand. Now you can adjust your lever position without tools, and protect your lever. ASV now offers four different applications for the rotator clamp; front brake, front brake with hot start, stock clutch perch or magura hydraulic / KTM clutch perch. Fits all bike/quad front brake master cylinders.
