The Triumph Thruxton 900 was named after the famous race course in England, the Bonneville Thruxton is reminiscent of the bikes of the 1960's that ran in the 500 mile Thruxton race circuit endurance race. 

Triumph won first, second and third in 1969, and the bikes of that era helped to create the "cafe racer" craze.

The new Triumph Bonneville Thruxton 900 has a revised engine of 865cc with new cams, carburetors and great-looking megaphone exhausts.  Power is now rated at 69 hp and 45 ft. lbs. of torque.
