The Triumph Thruxton 900 is a twin-cylinder, air-cooled British motorcycle manufactured and marketed by Triumph Motorcycles and launched in 2004. The Thruxton is heavily based on the company's Bonneville model, with hallmark café racer-style modifications — including clip-on handlebars, rear foot controls ("rear sets"), small fly-screen, white faced instruments, reverse cone exhaust silencers and bodywork with a prominent rear seat cowl and contrasting racing stripe.

The motorcycle is named after Thruxton Circuit, a race track where in 1969 Triumph won the top three places in the Thruxton 500 mile endurance race. These were the same races that established the "café racer" era, an era where standard production motorcycles were modified to improve street and racing performance.[1]

Design[edit]

The Thruxton features an engine upgraded from the Bonneville engine of the same model year, with new cams and pistons increased to 90 mm, taking capacity to 865 cc and power up to 70 bhp (52 kW).[2] Unlike the original Thruxton, which boasted top speeds over 140 mph (230 km/h), the new Thruxton achieves 120 mph (190 km/h).[3]

The frame is a tubular steel cradle with a twin-sided swingarm and traditional spoked wheels, 36-spoke (18 x 2.5 inch) front and 40-spoke (17 x 3.5 inch) rear. Front suspension has 41 mm forks with adjustable pre-loading and rear has chrome spring twin shock absorbers with adjustable pre-load. Front brakes are a single 320 mm floating disc and rear a smaller 255 mm disc, both with twin piston callipers.[2]

The Thruxton bodywork originally featured a checkered strip running longitudinally along the fuel tank and rear seat cowl. Beginning with model year 2007 a broad solid colour stripe replaced the checkered stripe, flanked by two thin stripes.

Triumph Thruxton Cup Challenge[edit]

In 2005, Triumph Motorcycles (America) Ltd. and the American Historic Racing Motorcycle Association (AHRMA) developed the Triumph Thruxton Cup Challenge at Pueblo Motorsports Park in Colorado as a “spec” class race limited to the Triumph Thruxton 900. Ted “Cannonball” Cobb, won the inaugural cup.[4]
