In 1969, motorcycle manufacturer Triumph Motorcycles, which is headquartered in England, went for a first-second-third place sweep at the Thruxton Circuit, a motor racing circuit named after the southern town where it was located. Thirty-five years later, Triumph released a standard motorcycle to commemorate the event. Called the Thruxton after the circuit, the 2004 bike is really a variant of the flagship Triumph Bonneville of the same model year, albeit a bit more polished and powerful.
The inaugUral version of the Triumph Thruxton was available in one of two color schemes: Jet Black/Silver and Sunset Red/Silver. The bike is 87.1 inches (2213 millimeters) in length, 28.1 inches (714 mm) in width, and 46.1 inches (1170 mm) in height, with a wheelbase of 58.1 inches (1477 mm). The dry weight of the Thruxton is measured at 451 pounds (205 kilograms).
Like the model years that would succeed it, the first Triumph Thruxton is sometimes referred to with a “900” suffix to signify its engine displacement, which is measured at 865 cubic centimeters (rounded up to 900). The engine on the 2004 Thruxton is a four-stroke, parallel twin (or two-cylinder) engine that pumps out 69 horsepower at 7250 revolutions per minute rpm and 53 lb-ft of torque. The engine uses a double overhead camshaft intake valve configuration and has an air cooler for preventing overheating. The bore and stroke for each engine is 3.54 by 2.68 inches (90 by 68 mm), and the compression ratio is 10.2 to 1. Triumph provides two carburetors for mixing fuel and air for the engine, and each bike has an electric starter to start the engine. Each engine on the Thruxton is paired with a five-speed manual transmission. Fuel capacity peaks at 4.2 gallons (16 liters).
Each 2004 Triumph Thruxton uses a steel frame and has the customary dressing, such as front and rear fenders. There’s a kick stand for enabling the rider to park the motorcycle, and the seat, which is set at a height of 31.1 inches (789.9 mm), can accommodate up to two people. Standard digital instrumentation consists of a tachometer, trip odometer, and speedometer. For enhanced visibility, Triumph provides exterior lighting and side mirrors.
Triumph provided the 2004 Thruxton with a pair of disc brakes for terrific stopping power. A 12.6-inch (320-mm) dual disc went to the front, while a 10-inch (255-mm) disc went to the rear. For absorbing bumps and providing smoother rides--especially on rough terrain--the 2004 Triumph Thruxton uses a suspension consisting of a 1.6-inch (41-mm) telescopic fork at the front and steel twin-sided swing arm, with two shock absorbers at the back. The bike rides on aluminum wheels: 18 inches at the front, 17 inches at the back, both wrapped in tubeless Pirelli® tires.
Within the next few model years, the Bonneville would emerge as the flashier and sportier standard bike while still sharing many of the Thruxton's components. However, for the 2004 model year, the Thruxton is the better of the two options.
