The Triumph Thruxton was a series of British machines powered by a parallel-twin engine mounted in a sports package. The bike was named after the Thruxton Circuit, a race track in Hampshire, where the maker won the top three places in the Thruxton 500-mile endurance race.
The first bike that used the name was the Thruxton Bonneville, a limited production hand-built racer that debuted in 1965. The bike was manufactured by the Triumph Engineering factory race shop in Meriden.
In 2005, the British motorcycle manufacturer launched the Triumph Thruxton, a cafe racer-style machine based on the Bonneville platform. The bike had the same visual, technical, and performance specifications as the previous model, except for new Racing Yellow and Caspian Blue color schemes.
The bike had standard features in the visual department, such as a round headlight with instruments mounted on top, a single seat with a passenger seat cover, side-mounted rear shocks, a dual exhaust system, and wire-spoke wheels.
In the performance department, the 2005 Triumph Thruxton 900 had its heartbeat set by an 865cc four-stroke parallel-twin air-cooled engine fed by twin carburetors, delivering 70 hp at 7,200 rpm and 72 Nm (53 lb-ft) torque at 6,400 rpm.
The engine power was handled by a five-speed manual transmission with a wet multi-plate clutch linked to the rear wheel through a final X-ring chain drive, pushing the motorcycle to 185 kph (115 mph).
