Triumph 350/500 unit construction twins bible 1957-1974

Aside from all the insider info required to be able to identify a model (or decipher whether it is or isn’t what is claimed!), there’s also plenty of hints and tips for identifying year and specification of parts, and for maintaining and modifying your bike if you’ve acquired one of the unit construction twins.

With lists of clubs, resources, sales figures and magazine reviews, it is part workshop manual, part easy reading and part reference manual. In short, if you have an interest in the subject matter, you should order a copy! Priced at £27.50, more details can be found at www.veloce.co.uk or on 01305 260068.
