TRIUMPH 750 "SLIPPERY SAM" Bol d'Or - 1970

Start of the last Bol d'Or in Montlhéry in 1970, 2 Triumphs (Smart/Dickie and Tait/Jolly) took the pole position. After 24h, Paul Smart (Barry Sheene's brother-in-law and Scott Smart's dad) and Dickie enjoy their victory. Triumph wouldn't have had any trouble during the 24 hours, except the change of an accelerating cable. By an irony of fate, it's the 750 Honda (victorious in 1969), which held the lead of the race during a few hours, which will give up because of an engine seizing ! Of course, the engine was (well) prepared, but, except a larger tank, a fairing and the Fontana front brake, the frame was original. Percy TAIT will give a repeat performance at the 1971's Bol d'Or, this time at Le Mans, with a machine close to the Daytona's victorious BSA the same year.
