Triumph Bonneville 790 cc motorcycle in the UK is designed and built in Hinckley, Leicestershire, Triumph Motorcycles Ltd., between 2001 and 2007, when the engine size was increased to 865 cc. Triumph launched its first Triumph Bonneville 790 15 year old in Munich Motorcycle Show in September 2000 with 790 cc, 360-degree crank parallel twin engine. Triumph of the development team was originally designed a prototype they call 9O8MD project in April 1997, the media conversion engine of an “entry level” for the export market. Market research shows that the legacy of Triumph is an important factor for foreign buyers, so the Export Manager Ross Clifford decided to develop a scheme of parallel machine, which can incorporate the latest technology with classic architecture of the engine.
The ability to “traditional” machine 750 cc and 650 cc original even considered before 790 cc selected. The 86 mm diameter works well with four valves per cylinder layout, while the stroke length of 68 mm allowed Conrod that helps minimize vibration secondary, but Triumph’s engineers also changed the bar to restore weight “character” a bit of vibration. David Stride designer may add details kept its original appearance, such as tubes and fins of the cylinder rod of the dummy (which serves as a resting oil the cylinder head) and internal oil lines to create a clean appearance. And the desired low and midrange performance, with a capacity of 115 machines mph (185 kph) and peak power respectable 61 hp (45 kW) @ 7400 RPM with maximum torque of 44 lbf ft (60 m N) @ 3500 rpm With 90% of torque available from 2,750 rpm up the rev limit. This machine is air-cooled like the original, but not a twin overhead camshaft pushrod valve operation with the old model. The frame mounted oil cooler ensures consistent running temperatures and camshaft drive is by chain between the cylinders and incorporates an idler gear that allows the cylinder head must be kept very compact.
