Road Racing History of the
TRIUMPH 500 Unit Twin
Claudio Sintich (l'Inglese)
Now Out of PrintFrom Dave Minton, Real Classic March 2011">I really do not know how many people Sintich interviewed, how many notebooks he must have filled, how many photo’ archives he must have searched to achieve the extraordinary volume of information he has. I do know, however, that it must have involved research, patience and endurance beyond measure over many years. Certainly, though, I cannot recall reading a more methodically presented, painstakingly researched, more comprehensive model history than this."
“This book...made me proud to have been part of the Triumph Engineering Racing Team.” Les Williams
"A remarkable piece of work and a very good book!" Percy Tait
From Nacelle (magazine of the Triumph Motorcycle Owners Club)
"Now here's a book for Triumph enthusiasts to have....
it is an exhaustive investigation into the road racing history of the Daytona Triumph Unit 500 Twin. Far from being a dry and possibly boring story that such a detailed work can be, Claudio's enthusaism for the racing Daytona shines through and he writes in an entertaining and very informative way....technical nuts are catered for with details of the engine and frame developments through the Daytonas high point of the 1960s, complete with graphs and measurements, but the follower of the actual racing is also well catered for with stories of its American, UK and European successes....In his research for the book Claudio interviewed the men involved in the racing project and he inserts snippets of the interviews in his race reports as the interviewee relates what went on during a race, giving it a feeling of life and immediacy.
This is one book about Triumph motorcycles that I can definitely recommend...." Martin Jones (Nacelle assistant Editor)
From Tim Britton of Old Bike Mart (July 2010)
"For a factory whose boss was so against racing, Triumph seem to be remarkably good at it and all the while using the most mundane of engines. Most of the inspiration for racing the unit construction 500cc engines machines seems to have come from the USA where Edward turner’s fearsome wrath was diluted a little. In his book Claudio Sintich details the start of the programme that would eventually lead to Daytona 200 wins, Percy Tait’s GP 500 and any number of specials. Naturally ‘how the factory did it’ features highly and if you’re in the process of constructing a unit engine even for the road, then there will be information here for you. Inside this book are details of races, the highs, the lows of putting a push rod twin into the highest category of racing, the characters involved, their escapades and …well even if you’re not into Triumph 500s this book is still an entertaining read. Go buy it."
A wonderful book on the amazing road racing history of the ‘fast but fragile’ Triumph 500 unit twin. From the Daytona successes of the mid ’60s to the end of the factory racers, including that fantastic second place to Agostini and the mighty MV in 1969, this book details the full history of the Triumph 500 unit twin racers. The story is told as much through the hundreds of period photos as in the carefully researched text; but wherever possible the words are those of the main protagonists themselves – the incomparable racers Percy Tait in the UK, and Gary Nixon in the USA, the Triumph racing team including Les Williams, Jack Shemans and Arthur Jakeman for example, and also the privateers such as David Kirby, Rob Prior and Dave Degens of Dresda fame, amongst many others. This is a book full of insight into those golden racing days for the little 500 unit twin. But perhaps just as interesting is the insight into the factory team that created this success with so little support from senior management, but which would later become the nucleus of the team which built the legend of the triples such as ‘Slippery Sam’. Complete with a great many photos, many never before published, this is a real gem.
