Triumph Classics Master Cylinder Cap – Brass/Aluminum

A durable, aesthetic upgrade for Bobber, Speedmaster and Bonneville

Instantly elevate the finish of your Triumph with this master cylinder cap designed for Bobber, Speedmaster and the Triumph Classics family. Made from solid brass or aluminum depending on the version, it replaces the original brake master cylinder cap (and/or the brake fluid reservoir cap, depending on the selected variant) for a more premium, more durable result that perfectly suits a bobber, classic or neo‑retro build.

Available in several finishes – brass for authentic charm, silver (aluminum) for a clean mechanical look, or black for a discreet integration – this cap adds a workshop touch to your cockpit. Titanium alloy screws (options gold or black) let you refine every detail while maximizing long-term durability. Each piece is designed to install in minutes, matching the original bolt spacing and sealing.

Whether you’re perfecting a subtle customization or replacing a cap marked by time, this component brings real benefits: a bold visual presence, enhanced durability and superior tactile quality. And because personalization is in the details, you can choose the position and finish that suit your setup: brake fluid reservoir cap, large left cap or small right cap depending on your model.

Why upgrade the stock part?

OEM caps are often functional but visually basic. Over time, they can scratch, fade and lose their shine, especially when in contact with brake fluid. This quickly clashes on a meticulous build and drags the overall look down.

• Uninspiring, overly standard OEM look

• Marks, scratches and dulling over time

• Painted finishes sensitive to cleaning products

With this brass or aluminum cap, you gain a strong visual signature and improved resistance to wear. The replacement is direct, the fit precise, and the available finishes let you harmonize your cockpit with your Triumph’s style.

Ideal use:

• Elegant bobber or classic build on Bonneville Bobber and Speedmaster

• Refresh the cockpit on Bonneville T100/T120

• Discreet, high‑quality custom on Street Twin/Street Scrambler

• Replacement for a scratched, dulled or damaged cap

• High‑end finish for show bikes and restomods
