1967 Triumph 649cc TR6R Trophy
Registration no. BBD 172E
Frame no. TR6R DU72810
Engine no. TR6R DU72810

By the time Triumph introduced unitary construction of the engine/transmission assembly on its 650 twins for 1963, the TR6 Trophy had long been established as the single-carburettor companion to the twin-carb Bonneville, whose specification in all other respects it closely followed. However, although the pair possessed an impeccable engine, Triumph's larger models were widely recognised as lacking in the handling department, especially when compared to rivals Norton. Following the wholesale changes of frame layout in the late pre-unit era, a single down-tube design was introduced on the 650cc 'unit' twins, although even this would undergo several detail alterations over the next eight years. The most important 'tweak' to the Trophy/Bonneville frame was made for the 1967 model year, when a shallower steering head angle was adopted in the interests of better high-speed stability, and road testers duly reported a marked improvement in that respect. By this time Triumph's two '650' sportsters had been updated with 12-volt electrics and a full-width 8" front brake, while other significant improvements for 1967 included a new oil pump and an increase in the Trophy's compression ratio to 9.0:1, same as the Bonneville's.

First registered in the UK in 2004 (almost certainly imported from the USA), this apparently original matching-numbers TR6R Trophy has been checked over by the vendor mechanically but left untouched cosmetically. The machine is offered with an old-style V5C document and HPI check. Recommissioning advised.
