Triumph Bonneville 750 T140E Final Edition





















Development History

The original Triumph Bonneville
was named after the Bonneville Salt Flats in the state of Utah, USA, where
Triumph and other motorcycle companies made attempts on the world motorcycle
speed records. It was popular (particularly in its early years) for its
performance, compared to other bikes available. Although later enlarged to
750 cc, in the late 1970s and early 1980s it suffered when compared to more
modern and reliable Japanese motorbikes from Honda and other manufacturers.
The T120 engine, both in standard configuration and especially when tuned for
increased performance, was popular for installing in café racers such as
Tribsas, and particularly Tritons.

T120 Bonneville

The original Triumph Bonneville
was a 650 cc parallel-twin (two-cylinder) motorcycle manufactured by Triumph
Engineering Co Ltd and later by Norton-Villiers-Triumph between 1959 and 1974.
It was based on the company's Tiger 110, and was fitted with the Tiger's
optional twin 1 3/16 in Amal monobloc carburettors as standard, along with
that model's high-performance inlet camshaft. Initially it was produced with a
pre-unit construction engine which enabled the bike to comfortably achieve
115 mph without further modification, but later (1963), a unit construction
model was made which was more compact and added slightly to the stiffness of
the set-up, together with additional bracing for the steering head and
swinging arm. The steering angle was altered and improved forks were fitted a
couple of years later, which, together with the increased stiffness enabled
the overall performance of the Bonneville to match that of its rivals.

T140 Bonneville

Developed from the later 'oil in
frame' (based on that of the BSA A65) version of the T120, the first few
T140s, designated T140V, featured a larger capacity engine of 724 cc, a
five-speed gearbox option and indicators, but still retained drum brakes and
kick-start. Shortly after, the engine was further bored-out to 744 cc and
front disc brakes were fitted (single discs before 1982). In 1975, along with
engine modifications, the gearchange lever was moved from right to left to
comply with regulations introduced for the American market. Several T140
models followed featuring various modifications and refinements until
production ceased with the closure of the Meriden works in 1983.
