Sharing Our Triumph Secrets

We here at British Customs live and breathe Triumph. Our passion translates into the Triumph motorcycle parts we produce and work with as well as the builds we create. 

Years of trying different parts and modifications on various bikes have accumulated us a wealth of information and knowledge to support you as you make your bike your own. Head to our Shop Notes on our blog to find everything from fitment notes, Triumph model updates, or our tuning guide.

We Only Sell What We’d Ride

Our aftermarket motorcycle parts aren’t just designed by us. They’re tested by us — we ride our bikes in all kinds of different environments and applications to see how they perform. With the feedback we get from both our own riders and our customers, we tweak designs until we get our parts right, and only carry Triumph parts that we’ve tried and installed ourselves to meet our standards.

To learn more about how we’ve put our bikes to the test, check out our On the Road photo journals on the blog to keep up on our adventures.

Get Inspired By Custom Builds

Our custom builds demonstrate the way we use British Customs Triumph motorcycle parts to re-imagine and transform stock Triumphs. Our in house bikes have been built up numerous times in various forms that we’ve kept notes on. We also feature guest bikes we’ve collaborated on with riders in the Triumph community.

You can view our builds and learn more about what has inspired our bike projects and get the specifications of each different build in our portfolio.
