Slippery Sam is a British production class racing motorcycle from the early 1970s that used a carefully prepared version of the 750 cc Triumph Trident ohv (pushrod) three-cylinder engine. The "Slippery Sam" name was acquired during the 1970 Bol d'Or, a 24-hour race for production-based machines held in France, when engine difficulties and escaping oil covered the bike of Triumph employee Percy Tait and co-rider Steve Jolly who managed to finish in fifth place to winners Paul Smart and Tom Dickie on another works Trident.
'Slippery Sam' is known for winning five consecutive production 750 cc class TT races at the Isle of Man between 1971 and 1975. The machine, which was displayed at the National Motorcycle Museum, was destroyed in a fire during 2003,[1] but has since been completely rebuilt.[2]
