The Triumph Thruxton 900 is a British motorcycle made by Triumph Motorcycles, Ltd. Launched in 2004, it was named after the Thruxton racing circuit where Triumph won the first three places in the Thruxton 500 mile endurance race in 1969, establishing the "café racer" era where standard production motorcycles were modified to improve racing performance.  Triumph's designers had developed the successful Triumph Bonneville, adding clip-on handlebars and rear set controls, with a cowl for the rear seat and 'Megaphone' silencers. Instruments were faced in white and a chequered stripe completed the "café racer" look. Beginning in 2007 a new solid colour stripe was used, featuring a broad centre stripe flanked by two thin stripes.  The engine was also upgraded with new cams and pistons increased by 90 mm, taking capacity to 865 cc and power up to 70 bhp (52 kW).
