Black anodized Contrast Cut machined. For models with hydraulic operated handlebar clutch control. CNC machined billet aluminum construction with the unprecedented attention to detail for which Performance Machine is known. Includes chrome installation hardware and gaskets. Fits as a direct replacement for the OEM transmission end cover. Note: With a hydraulic clutch PM recommends a 11/16″ bore handlebar master cylinder since a 9/16″ bore may not transfer enough fluid to fully disengage the clutch.
