Available in either brake or clutch format. Machined from high quality billet aluminum. The piston’s High Energy actuation system uses a three sealed ball bearing system that allows the piston to travel in a parallel fashion to the cylinder bore with minimal stiction, side loads, seal compression or extension. Giving a superbly smooth and easy actuation, resulting in more clutch line pressure with less effort on the lever and less rider hand fatigue. The Mastercylinder also has ‘span’ adjustment, that features a self locking ‘click’ thumbwheel.
