Triumph launched the first new Bonneville for 15 years, the Bonneville 790, at the Munich Motorcycle Show in September 2000, with a 790 cc (48 cu in) 360° crankshaft parallel-twin engine. The T100 Bonneville, styled by John Mockett and David Stride, was launched as an uprated version initially with the 790 cc engine, and from 2005 with the 865 cc engine introduced on the 2004 Thruxton, and fitted to all Bonnevilles from 2007. The designation comes from the T100 models produced by Triumph between 1939 and the mid 1970s and it is sold as part of Triumph's "Modern classics" range. The engine features double electrically heated carburettors. Triumph added an air injection unit near the spark plug to achieve emission regulations introduced in 2007. For 2008 the T100 (like all Bonneville based models) was further updated with fuel injection to meet new Euro 3 emissions legislation. As well as cleaner running than a carburettor engine, the fuel injected system is also easier to start from cold. To retain the 'retro' styling the fuel injectors are hidden behind throttle bodies designed to resemble carburetors.
