Triumph 350/500 Unit Construction Twins Bible: 1957-1974

thought this would have mainly information to work on your bike, parts crossover and to how improve/upgrade it, but there is very little of that. most of the book being a year by year guide to the spec and changes made year by year during manufacture.

for all you bikers out there..this is well worth buying.....safe riding.

Fantastic book, lots of useful information to help anyone interested in these bikes

Excellent speedy delivery. husband loved it. His actual bike was also in the book as first one on production so that pleased him. Generally a great book for bike lovers
