We digitised the factory parts book for the Triumph 350-500 Unit and indexed every figure and part number, so the bolt, gasket or gear you need is a couple of clicks away — and you can be sure it's right for your bike.
We took the original Triumph 350-500 Unit factory parts books and rebuilt them, page by page — every exploded diagram and every part number, cross- referenced against current supersessions so you're ordering the current part number, not one that's been superseded.
Triumph changed specs mid-season, so the right part depends on your exact year. Pick your year below, or send us your engine number and we'll place your bike in the correct book — no guessing, no wrong-year parts. Decode your VIN ›
