Triumph T140, TR7, T150, & T160 Master Cylinder as used on Disc Brake Twins and Triples 1973-78 with the added bonus of a 13mm (1/2″) Bore Stainless Barrel. These are made specifically with a Stainless Steel Cylinder Barrel to alleviate the rust & pitting issues that plagued OEM Master Cylinders while visually replicating the OEM item. This part is bored 1mm smaller (1/2″ / 13mm bore) than stock which is better suited for the Lockheed calipers than the OEM 5/8″ bore. Beautiful UK made reproduction supplied with chrome lever. The best of the best from LF Harris.
