Triton motorcycles were not factory models but were hybrid bikes built in the 1960s and 1970s. Many were privately constructed but some London dealers offered complete bikes. The builders fitted Triumph engines into Norton frames. The name 'Triton' is a contraction of Triumph and Norton; and 'Triton' was the name of a mythological Greek God. The Norton Featherbed frame was regarded as the best handling item of the day. A popular engine choice was the Triumph Bonneville unit with twin carburetors and twin camshafts. This pushrod engine gave good performance and reliability and could be more easily tuned for greater power using high-profile camshafts, high compression pistons and twin carburetors. In due course, a Weslake 8-valve head became available for the Triumph motor.
