Paste a number. We'll tell you the bike.

Engine numbers, frame numbers, full VINs, even bare serials. Covers every UK Triumph twin from 1950 through 1983 (plus Les Harris 1985–88), BSA unit bikes, and Norton — the Commando plus the classic Dominator, Atlas and singles back to the 1920s. Triumph decoding is the most complete; BSA and Norton years are approximate — always confirm against the stamping.
