The Triumph
Bonneville is a standard motorcycle featuring
a parallel twin four stroke engine . T120 Bonneville used a
new frame which contained the engine oil instead of using a separate tank. This
became known as the oil in frame version. The T120 engine, both in
standard configuration and especially when tuned for increased performance, was
popular in cafe racer such as Tribsas (BSA frame) and particularly Tritons
(Norton feather bed frame).
