The third series, by Triumph Motorcycles in Hinckley, Leicestershire, began in 2001 and continues to the present equally a completely new blueprint that strongly resembles the original series.

The name Bonneville derives from the famous Bonneville Table salt Flats, Utah, USA where Triumph and others attempted to break the motorcycle speed records.^[ane]

Evolution history [edit]

T120 Bonneville [edit]

The original Triumph Bonneville was a 650 cc parallel-twin motorcycle manufactured by Triumph Engineering and later by Norton Villiers Triumph betwixt 1959 and 1974. It was based on the company'south Triumph Tiger T110 and was fitted with the Tiger'southward optional twin 1 3/16 in Amal monobloc carburettors as standard, forth with that model'southward high-performance inlet camshaft. Initially it was produced with a pre-unit construction engine which enabled the bike to attain 115 mph without further modification, but afterwards in 1963 a unit construction model was introduced which was stiffer and more than compact, including additional bracing at the steering head and swing arm. The steering bending was altered and improved forks were fitted a couple of years after, which, together with the increased stiffness enabled overall performance to match that of the Bonneville's rivals.^[two] Later T120 Bonnevilles used a new frame which contained the engine oil instead of using a separate tank; this became known every bit the oil in frame version. The T120 engine, both in standard configuration and particularly when tuned for increased performance, was popular in café racers such equally Tribsas (BSA frame) and particularly Tritons (Norton bypass frame).

T140 Bonneville [edit]

The early 650 cc T120 Bonneville, often known every bit the duplex frame model,^[three] was replaced in the early 1970s past the T140 Bonneville, the same basic machine simply with a 750 cc engine. Refined from the later on 'oil in frame' version of the T120, the first few T140s, designated T140V, featured a larger-chapters engine of 724 cc, a five-speed gearbox option and indicators, but still retaining drum brakes and kick-get-go. Presently afterwards, the engine was further bored out to 744 cc and front disc brakes were fitted using single discs until 1982. 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 place and a rear disc brake fitted. Several T140 models followed featuring diverse modifications and refinements including electrical starting from 1980 until production ceased with the closure of the Meriden works in 1983.^[4]

Although this should have been the terminate of the Bonneville, equally it turned out it was not. Triumph Motorcycles was acquired by businessman John Bloor, who licensed a company called Racing Spares in Devon, run by Les Harris to manufacture the T140 Bonneville. These continuation bikes are known as the 'Devon Bonnevilles', which did not reach the market until 1985, and were not sold in the U.S. Production ended in 1988.^{[five] [6]}

New Bonneville (800, 900 & 1200) [edit]

Bloor's Triumph Motorcycles Ltd launched a completely new model, the Bonneville 800 (790cc), in September 2001. Originally congenital exclusively in Hinckley, England, some models are now (2014) produced at the company'due south Thailand manufacturing facility, which also makes components and accessories for various Triumph motorbikes. The new Bonneville strongly resembles the earlier models in manner and basic configuration, simply with modernistic engineering. At the debut the new version was given a 790 cc parallel-twin engine, with the up-spec T100 receiving an 865 cc engine from 2005. From 2007 on, all Bonnevilles received the 865 cc engine. Through 2007, all engines had carburettors; electronic fuel injection (EFI) was then introduced to the 2008 models in Britain and to United States models in the 2009 model yr, in both cases to comply with increasingly stringent emissions requirements. Dummy carburettors, which are actually redesigned throttle bodies made to resemble carburettors, have been added to the 2009 models to retain the original vintage styling of previous years. For 2016, Triumph introduced an all new T120 1200cc 270° liquid-cooled, SOHC, version of the Bonneville, then in 2017 a T100 900cc version.

From 2008, all Bonnevilles received a slightly larger and reshaped tank to accommodate the EFI pump, but the tank chapters was not contradistinct. Fifty-fifty though Us 2008 models were non injected they still received the larger tank, therefore the infinite for the pump was not used.

All the bikes in Triumph's electric current "Modern Classics" line are derived from the new Bonneville, including the SE (with a smaller front wheel to be marketed to riders who may have found the 19' bike too tall), T100, Thruxton, Scrambler, America, and Speedmaster.

In 2006, Triumph launched the "Threescore-viii" line of Bonneville accessories, offer vintage and modern-fashion items including seats, seat covers, cam covers, sprocket covers, petrol tank covers, tank badges, panniers, and other items to allow Bonneville owners the opportunity to customise their bikes for considerably less toll than traditional customisations. The adoption of the EFI engine in 2008 rendered many of these accessories obsolete, since tank covers, tank badges etc. would not fit the redesigned tank.

The original T120 Bonneville was a speed-orientated motorcycle, but the new Bonnevilles are softer and aimed at the roadster market. In detail, the 865cc Bonneville competes directly with the Harley-Davidson 883, with MotorCycle News declaring that "Triumph Bonneville is unquestionably the ameliorate motorbike. The handling is more than respectable, the brakes markedly better and, of class, information technology's British."^[7]
