Here’s a chance to own a true café racer icon — a 1956 Triton 500, combining a Triumph pre-unit twin with a Norton Featherbed slimline frame. This machine was originally purchased for display in our showroom but deserved so much more. Now, after a thoughtful and sympathetic refurbishment, this Triton is very nearly ready to return to the road.

📜 Notes:

This Triton is not a kit or tribute — it’s a thoughtfully built vintage café racer that blends authenticity with functional upgrades. The engine, frame, and component choices are all in line with how serious Triton builds were done in the 1960s and ‘70s.

A few final details and tuning steps remain before it's 100% road-ready, but it’s very close to completion and will reward its next owner handsomely.
