TRIUMPH TRIDENT ROB NORTH - 1971
Percy Tait

At the beginning of 1970 Triumph's main objective was a victory in Daytona. Percy TAIT contacts Rob North for the realization of a frame. The factory also follows. Two teams are created, Triumph with a white-blue colour and BSA with a white-red colour. Very quickly this bike is covered with glory : amongst others, a 2nd place in Daytona in 1970 with Gene Romero (Mike Hailwood even leads with the BSA before breaking engine), victory in 1971 with Dick Mann on BSA, 2nd and 3rdplace with Gene Romero and Don Emde on Triumph and victory at the Bol d'Or in 1971 with Percy TAIT and Ray Pickrell on Triumph.
