If you can recall the golden era of motorcycle sport then this is undoubtedly the book for you. Featuring sixteen scramblers and one and six days trials stars, this is a must read for all who lined the circuits on muddy Sundays and were glued to their TV sets on Winter afternoons. Author Andy Westlake is regarded as one of the UK's leading classic motorcycle journalists and this book is the perfect follow-up to his two previous books "Off Road Giants" volumes one and two. In this third volume Andy has once again managed to track down and interview some of the stars of this golden era in off road sport, including the former works Greeves rider and 250cc European champion Dave Bickers, ex works BSA star John Banks, and has even journeyed to Spain to interview Les Archer, the man who lifted the European 500cc crown on his works Norton in the mid 'fifties. A superbly written book brought alive by many excellent period photographs.
