Lot 370: c.1972 Triumph 890cc Trident ‘Slippery Sam’ Replica

Professor Fritz Ehn Motorcycle Museum Collection, Bonhams (30 June 2008)

Although up-staged in the showroom by Japanese rivals, the Triumph and BSA 750 triples did more than enough on the racetrack to ensure their place in motorcycling history. BSA-Triumph’s Chief Engineer Doug Hele supervised engine development throughout 1969 while frame builder Rob North devised a chassis that would stand the test of time like few others. The team narrowly missed victory at the 1970 Daytona 200, its first major event, when Gene Romero finished second on a Triumph. Dick Mann’s BSA won at Daytona in 1971 and John Cooper, also BSA-mounted, at Mallory Park’s Race of the Year, vanquishing the hitherto unbeatable combination of Giacomo Agostini and MV. Percy Tait and Ray Pickrell had won the 24-hour Bol d’Or endurance race the preceding week on another Triple, and Cooper wrapped up a memorable international season for BSA-Triumph with victory in the 250-mile race at Ontario in October. As a production racer the Triple was equally dominant, as the number of important production race victories achieved (most notably by the famous works Triumph known as ‘Slippery Sam’) is eloquent testimony. After the dissolution of BSA-Triumph, race shop foreman Les Williams continued to develop the Triples, producing the acclaimed, limited edition Legend and constructing a number of replicas of the multiple TT-winning ‘Slippery Sam’. Williams having led the way, ‘Sam’ has remained a popular subject among replica-builders ever since. This ‘Slippery Sam’ replica was brought to Austria from the UK in 1994 and purchased by Professor Ehn. On Museum display ever since, following an extended road test, the machine is offered with UK V5 registration document and customs documentation.
