Just an update on the book 'The Sunbeam Motorcycle'  by R C Champ. We have altered our Categories on the Spares List to include a separate section for Books and DVD's at the bottom of the Spares List, so this book is now Item No. P1 - 2.

thanks for the info the de.scription matches my model 2. Perhaps i am too hung up on the frame number but it was covered over when i bought it and i needed to strip the finish back to get to it and i desperatley wanted a banbury eligible bike.

The frame number A3nnn would indicate a 1929 Model 1 or 2, 2 having a more 'sporting' specification with a chainguard rather than full chaincase, blade mudguards and flat handlebars. The engine number H3nnn also indicates a 1929 M1 or 2. An A5nnn frame number would be 1930.

Thanks for the information i have just uncovered the vin on the headstock of my 1929? model 2 but the first number after the suffix letter A is hard to make out as it is incomplete.The old and new log books have it as a 3 but it could be either 3 or 5 on the bike. Does anyone know what bike should an A3 or A5 relate to? The engine number is clear and is H3.

One of the problems with Sunbeam numbers is that they changed the number system every 3 years or so. Many of the prefix numbers do not relate to the models, and are probably batch numbers. If you have a query on frame and engine numbers, Bob Champ's book is the best source of data. I can help by reference to the register and to a listing compiled in the 1950s which seems pretty good for models up to 1930. My contact details are elswhere on the site.

Thank you for a good article, is there a listing of bike suffix letters/numbers by model and year.
