Triumph Pre-Unit Twins (Crowood Motoclassics) Hardcover – Illustrated, June 1, 2012

As an owner of several Pre-unit Triumphs, this book more than met my expectations. I gave it as a gift to another Triumph owner!

again, a very thorough and detailed comprehensive compilation of the model and its evolvement throughout the years of manufacture. mr vale is vey thorough in his research and presentationr

An excellent book. Very well documented and the photo quality is excellent. Very well researched by a dedicated author. Would recommend the book to an experienced enthusiast and to a complete novice.

I bought this for my Dad, whom had a Triumph Thunderbird, back in the 60's. He found his exact bike and some technical engine-diagrams in the book. It's techie and geeky; and, if that's what you need, then it's a great book.

Brilliant book.

Not the best.

Covers the subject well.
