Vintage Triumph Parts FAQ

Why are Triumph motorcycle accessories so expensive?

Companies that produce replacement and custom parts for Triumphs (and other vintage bikes) are spending a lot of time and energy developing and manufacturing parts that sell to a limited clientele. This tends to drive the price up, as smaller quantities of Triumph parts are sold compared to, for instance, windshields for late-model Harley touring bikes.

How to make my Triumph Bonneville faster

One way to make a motorcycle faster is by increasing it's horsepower. Increasing displacement by installing a big bore kit is one way to do so, as is having a high-flow air filter and exhaust system. Carbureted bikes can be tuned on a dyno to accurately test and fine tune a motorcycle to get the most power available.

How to make my Triumph Bonneville louder

Making a Triumph louder can be achieved by simply removing baffles from the stock mufflers, replacing them with aftermarket, free-flowing mufflers, or by running straight (no restriction such as baffles) header pipes.
