What year is it?

Your best bet would be to get one of Roy Bacon's buyer's guides with a section on the arcane and obscure serial number system used by Triumph. It changed several times over the years and is inconsistent and very confusing for the neophyte. Years may vary according to when the bike was announced, actually produced or exported. There is a grey area in determining exact years of production for some models.

If you can't find one of Bacon's books, you can get a good digest of the system (as well as the serial numbers for BSA and Norton) through a catalogue from British Cycle Suppy in Wolfeville, Nova Scotia, Canada at  britcycl@fox.nstn.ca or call (902) 542-7478 (fax: 902-542-7479). They are a good source of parts, accessories and books. Or check out Walridge Motors Ltd. in London, ON (519-641-2770 or walridge@gtn.net). Bother are good sources for books and information. Tell them I sent you...

Note re model suffixes: Pre 1961, A denoted pre-unit street bikes, and B meant competition model. After 1960, R replaced A and C replaced B. SS meant Street Scrambler and SC street-competition.

Notes:

This page will be updated as often as I uncover new sources, information and corrections. There is a lot of often conflicting data to try and sort through about models, numbers, designations and years of production. Latest update to this page: Oct. 14, 1998. Note that many pre-WW1 models did not have model numbers or names, but were simply refered to by engine output, engine type or size.

Most of the above data for UK models was drawn from various books by Roy Bacon and Ivor Davies noted in the bibliography, but also from other sources such as motorcycle magazines and other books. If any dates or models above are incorrect, or differ from notes in Bacon's or Davies' works, their dates should be assumed as the correct one, and those above are assumed incorrect. It's worthwhile getting the original books just to be sure. They're a great read, full of information and anecdotes, well worth having on your bookshelf.

There were numerous models made strictly for the American market, and their identification and dates may be different from UK models. The best source of this data is Triumph Motorcycles in America, by Lindsay Brooke and David Gaylin. Most of the models with question marks after dates are identified in their book for US entry. It's a great book and a wealth of information and photos.
