Background
Built between 1959 and 1975, the Triumph Bonneville had an unusually long-lasting production cycle. Edward Turner’s last design for Triumph, the 649cc ‘bike has a top speed of 108mph thanks to the 46bhp/36lb.ft air-cooled twin-cylinder engine.
A large part of that performance is down to its weight, which is just 402lbs/182kg. This absence of mass gives the Bonneville very good handling too, and this winning combination saw the T120 win on the track as well as in the showrooms.
Ridden by legends such as Mike Hailwood, it won multiple times at the Isle of Man TT, including a record-breaking 100mph average in the hands of Malcolm Uphill.
And the name? It came from the Bonneville Salt Flats in Utah, where Texan racer Johnny Allen set a two-way speed of 193.3mph on his methanol-fuelled Triumph special, ‘Devil’s Arrow’.
