British Customs has developed a solution for the bulky front brake reservoir: a CNC machined, black billet replacement unit that enhances the look of your 7/8" controls equipped Triumph. Our Reservoir upgrade kit goes well beyond mere dress up of the stock reservoir with a new cap or “sweat band” cosmetic cover -- it’s a complete replacement, smaller, sleeker and machined from billet aluminum and anodized black. It fits directly into the Nissin master cylinder* with a machined adapter and o-ring seal, eliminating the stock hose, and comes equipped with a Brembo O-ring. Made without a sight glass, our unit will never have fogging or leaking sight glass issues
