The Triumph Rocket III was a cruiser motorcycle made by Triumph Motorcycles Ltd that debuted in 2004 and continued production until 2017, when it was replaced by the Triumph Rocket 3. The bike had the largest displacement engine of any production machine until it was succeeded.
In 2004, the British motorcycle manufacturer launched the Triumph Rocket III. This cruiser motorcycle had standard features, such as two small round headlights, a single seat, an exhaust system with two mufflers on the right one on the left, and five-spoke lightweight aluminum wheels.
The bike was built on a tubular steel twin-spine frame with a 43 mm upside-down telescopic fork on the front and an adjustable shock absorber on the rear, providing optimum suspension performance and handling.
In the braking department, the bike's wheels were fitted with two 320 mm floating discs tied to four-piston calipers on the front and a 316 mm disc with a dual-piston caliper on the rear, delivering excellent stopping power.
Underneath its fuel tank, the 2004 Triumph Rocket III had installed a massive 2,294cc four-stroke three-cylinder liquid-cooled engine fed by a fuel injection system, delivering an output power of 142 hp at 5,750 rpm and 201 Nm (148 lb-ft) torque at 2,500 rpm.
The bike's power was handled by a five-speed manual transmission with a wet multi-plate clutch linked to the rear wheel through a final shaft drive, pushing the motorcycle to 219 kph (136 mph).
