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.
