RACING BIKE TRIUMPH TRIDENT 830CC "ROB NORTH" The end of the 60s for the European motorcycle industry marked the beginning of one of the least happy times, thanks to the arrival on our markets of Japanese motorcycles. The British opted for a three-cylinder engine and at the end of 1968, Triumph presented its flagship, the T150 better known as the Trident, 750cc.

BSA-Triumph chief engineer Doug Hele spearheaded engine development throughout 1969, while chassis 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, with Gene Romero finishing second in a Triumph. Dick Mann's BSA won at Daytona in 1971 and John Cooper, also mounted on the BSA, at the Mallory Park Race of the Year, defeating the hitherto unbeatable combination of Giacomo Agostini and MV.

Percy Tait and Ray Pickrell had won the Bol d'Or 24-hour endurance race the previous week with another Triple, and Cooper concluded a memorable international season for BSA-Triumph with victory in the 250-mile race in Ontario in October. Financial hardship meant that there was no labor effort in 1972, but the privateers kept the Triple winning for many years. Miles Engineering subsequently acquired the rights to the North chassis and continued production, ensuring that the BSA-Triumph triples remain a powerful force in today's classic racing.

Rob North frames are currently manufactured by Trident Engineering. This Miles chassis "big bore" Trident features a rebuilt engine and transmission, while the brakes, rims, exhaust horn, tachometer, seat, fairing and rear tire are new. Machine specs include Wiseco 11.0: 1 pistons, Carillo connecting rods, standard (heavy) crankshaft, reworked cylinder head, close shift gearbox, Amal Concentric Mk1 carburettors, Boyer ignition, high-output generator and lightweight aluminum
