We digitised the factory parts book for the Triumph Pre 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 Pre 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number, cross- referenced against current supersessions so you're ordering the current part number, not one that's been superseded.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 ›
Open the diagram for your Triumph Pre Unit, click the part on the drawing, and it drops straight into your cart with the correct number and price. No decoding microfiche, no cross-checking three catalogues — just point at the part you need.
Each book covers a specific run of the Triumph Pre Unit. Open one to browse its interactive diagrams.
