Triton Classic Motorcycles

The Triton was a modified Cafe racer motorcycle of the 1960s-1970s. The name derives from a contraction of Triumph and Norton; the two brands of motorcycle combined.

The intention was to combine the best elements of each to give a superior bike to either. The usual practice was to take the Triumph parallel twin engine and use it to replace the engine on a Norton "featherbed" framed motorcycle that was regarded as the best handling motorcycle of the day. The Triumph Bonnevilles engine that already had twin carburettors was a popular engine choice. This engine, as well as other Triumph twin-cylinder engines, gave good performance and reliability and could be easily tuned for greater power by the addition of high-profile camshafts, high compression pistons and twin carburettors or fuel injectors amongst the more common power contributing modifications. There was also a Weslake 8 valve head available for the Triumph.

Several motorcycle dealers made equipment for Triton conversions, some would do the complete job for customers while others sold complete Tritons. The most important part required are the engine mounting plates and several different designs exist that can affect the engine placement and therefore the handling. The lower the engine is mounted the better the handling achieved from the Norton frame.

The Tribsa, an alternative to the Triton, was a Triumph engine in a BSA frame but other frame and engine combinations were also made. Vincent V-twin motors have been fitted into featherbed frames making a hybrid called a Norvin.
