Monza Fuel Cap | Triumph

You change the fuel cap first for the style: it is a visible part that instantly transforms the look of the tank and the front of the bike. A billet cap like the Monza brings a vintage, sporty character that the original part lacks. Beyond looks, a good cap also ensures sealing and tank pressure management. On a neo-retro Triumph, it is one of the simplest accessories to personalise your machine.

A Monza-style cap is a fuel cap with a design inspired by racing motorcycles, recognisable by its compact shape and knurled top. It screws in place of the original cap and brings an instant race look. This style, popular in the cafe racer and neo-retro world, often comes in several finishes and materials. It combines vintage looks with modern safety and sealing functions.

It is compatible with a large part of the Triumph Modern Classic range, including the Bonneville T120 and T100, Speed Twin 900 and 1200, Bobber, Speedmaster, Thruxton, Scrambler 900 and 1200, as well as the Street Twin, Street Scrambler and Street Cup. Refer to the detailed compatibility list with model years. If you are unsure about your version, check with us before ordering.

Fitting is simple and quick: 1) Open and remove the original cap from your tank. 2) Present the Monza cap on the tank opening. 3) Screw it in place using its threaded lower section, helped by the knurled top for grip. No modification to the tank is needed, the cap fixes in place of the original.

The material depends on the finish. The gold version is made from aviation-grade brass, while the black and silver versions are made from 6061T aluminium. In both cases, the part is machined from billet, which guarantees strength and durability. These materials resist high pressure and temperature changes well, for added longevity even in demanding conditions.

Yes. The cap features a spring valve linked to three vents, which releases the pressure built up in the tank in a controlled way and avoids any risk of overpressure. It also has a fuel-resistant O-ring, which guarantees a perfect seal and prevents leaks. This system ensures both the safety and the protection of the tank.
