Background
Bonneville. It may sound a lot more exotic than Birmingham but Triumph’s signature model is crafted much closer to the UK’s West Midlands than USA’s Utah – Hinkley, to be precise. It’s been in continuous production now for 64 years and is one of the most recognisable names in the motorcycling world.
Built between 1959 and 1975 in Meridon, (again in the West Midlands), the original Triumph Bonneville T120 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? Well it did of course come 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’.
In 1973 the engine was increased in size and the T140 Bonneville 750 took the baton, with the 650cc models phased out in 1975. The larger engined bike continued to be produced at Meriden until 1983, when financial problems forced the closure of the Meriden factory and the company was bought by businessman John Bloor.
Bloor licensed production of an updated T140 Bonneville to Les Harris in Devon, who built the model until 1988. In 2001 Bloor’s new state of the art Hinkley factory started production of the all new Bonneville 800 model, which featured a 790cc parallel twin engine styled just like its illustrious predecessors, but with modern engineering and production techniques.
Today you can buy a Bonneville with an engine as big as 1200cc, but despite the increased engine size, Edward Turner would still recognise it as one of his own.
