IF YOU'RE LOOKING for an
all-weather, all-purpose, everyday classic British bike, you’re probably
staring straight at a 750cc T140 Triumph Bonneville.
A lot of negative criticism
has been hurled at these machines, notably citing problems with vibration and oil
leaks.
But the fact remains that
these machines offer excellent handling, good braking, decent enough
suspension, an acceptable turn of speed, and have better parts back up than
just about any other classic British bike in the market place.
The Triumph Bonneville is a
standard motorcycle featuring a parallel-twin four-stroke engine and
manufactured in three generations over three separate production runs.
The 650 cc capacity
production T120 Bonneville was replaced in the early 1970s by the T140
Bonneville, the same basic machine but with a 750 cc engine. Refined from the
later 'oil in frame' version of the T120, the first few T140s, designated
T140V, featured a larger-capacity engine of 724 cc, a five-speed gearbox and
indicators, but still retaining drum brakes and kick-start.
Shortly after, the engine
was further bored out to 744 cc and front disc brakes were fitted (using single
discs until 1982). While originally intended for 'export only' the 750
Bonneville twin, caused so much interest among visitors to the 1973 motorcycle
shows, that Triumph decided to put the bike on the home market at the price of
679 uk pounds.
In 1975, along with engine
modifications, the gearchange lever was moved from right to left to comply with
new regulations mandated for the American market and a rear disc brake fitted.
The initial model of the
T140 line was the 'V', which stood for five-speed transmission which was a
Quaife design.
