DevelopmentCompared with the standard Bonneville, the Bonneville America has a very different ride, with the wheelbase extended {{convert|6.4|in|mm}} to {{convert|65.2|in|mm}}, making it {{convert|6.8|in|mm}} longer overall. The saddle was lowered {{convert|2.2|in|mm}} and the steering head rake angle increased by 4.3 degrees giving a 33.3 degree rake. The America had the Bonneville's {{convert|12.2|in|mm|adj=on}} front disc but the front wheel was reduced to {{convert|18|in}} diameter and the rear wheel to {{convert|15|in|mm}} with a larger {{convert|11.2|in|mm|adj=on}} disc brake. The America also had a larger fuel tank with a 'chromed' plastic console to house the filler, {{convert|4.5|in|mm|adj=on}} diameter speedometer and warning lights. The side panels were extended with sheet-metal covers over the passenger-peg brackets and perforated chrome fittings behind the carburettors to provide the 'retro look' of the air-filter covers from the 1960 Triumph twins. The rider's footrests were also moved to the front of the engine to create a 'cruiser' riding position.[1] 2007In 2007, the engine capacity was increased to 865 cc (carburated) delivering peak power of {{convert|54|bhp|abbr=on}} at 6,800 rpm, with maximum torque of {{convert|69|Nm|abbr=on}} available at 4,800 rpm. Fuel economy is approximately {{convert|45|mpgus}} city and {{convert|50|mpgus}} highway. The update included new 'reverse cone' chrome silencers, a new design of cast alloy wheels, adjustable clutch and front brake levers and a new all black engine finish with chromed covers. The chrome chain cover, pillion footrest hanger and upper fork shrouds were restyled and a more comfortable pillion seat fitted.[2] 2008In 2008, the UK version of the Bonneville America was further updated with an electronic fuel injection system to meet the European emission legislation, with the fuel injectors concealed by dummy carburetors.[2] The US version of the Bonneville America was not updated to EFI until 2009.
