This motorcycle hydraulic hand clutch master cylinder rod system features a 14 mm diameter piston and a 15 mm stroke length.It functions as a transfer pump for hydraulic clutch systems and is compatible with motorcycles requiring a piston size of 14x15 mm.The system includes an adjustable anchor head that accommodates various mounting configurations.Some models use a U-plate anchor; others require installation with an M10x1.25 threaded.For models with a slotted or threaded mounting point at the pump head, an 8.2 mm drill bit may be used to prepare the mounting.Installation requires bleeding the hydraulic system to remove air: fill the reservoir with brake fluid, connect tubing to the side port without fully tightening the fitting, position the pump with the reservoir elevated, actuate the lever approximately ten times, allow fluid to flow from the open port for 5–10 minutes, then tighten the fitting.Proper function is confirmed when lever travel measures approximately 3 cm with firm resistance and no bottoming out, with the clutch fully extended during final adjustment.Compatible with a range of motorcycle models using hydraulic hand clutch systems.
