TRIUMPH Speed Four (2002-2003) Specs, Performance & Photos

The Triumph Speed Four was a standard or streetfighter motorcycle made by the British company from 2002 as the brother of the TT600 model that debuted in 1999. The Speed Four was manufactured until 2006, when it was succeeded by the Street Triple.

Like the Speed Triple, the Speed Four had two similar round headlights and a different frame and engine. It also packed a clip-o handlebar like the one used on the TT600 model instead of the motocross-inspired one packed by the Speed Triple.

Like its predecessor, the Speed Four packed the same cam profiles, ignition, fuel injection system, front spring rate, and other minor elements. Still, it packed a race-derived frame and fully adjustable suspension system.

In the aesthetic department, the motorcycle had standard features, such as two round headlights, a single seat with a passenger cowl, a four-into-one exhaust system with an up-swept silencer mounted on the right side, and three-spoke lightweight aluminum wheels.

The bike was built on a lightweight aluminum beam perimeter frame with a 43 mm fully adjustable telescopic fork on the front and an adjustable shock absorber on the rear, providing excellent handling capabilities.

Underneath its fuel tank, the 2002 Triumph Speed Four had installed a 599cc four-stroke four-cylinder liquid-cooled engine fed by an electronic fuel injection system, boasting 98 hp at 11,750 rpm and 68 Nm (50 lb-ft) torque at 11,000 rpm.
