The Triumph Speed Four is a standard or streetfighter motorcycle made by Triumph from 2002 through 2006. It is the naked, or non-faired brother of the TT600 sport bike introduced in 1999.
Design
The Speed Four has similar twin round headlghts to the Speed Triple, but a different frame and engine.. The Speed Four has the clip-ons handlebars of the TT600, rather than the motocross-inspired handlebars of the Speed Triple and other streetfighters.
The Speed Four is mechanically similar to its predecessor, the TT600, with the exceptions of the cam profiles, ignition and fuel injection mapping, front spring rate, and other minor concessions to its streetfighter style; the frame and fully adjustable suspension are race-ready.
The engine is a 599 cc inline-four-cylinder engine, the same engine in the TT600. The bike has a top speed of 135 mph (217 km/h) and a 0–60 mph (0–97 km/h) time of 4.5 seconds.[1]
Reception
The Speed Four was voted No. 1 for handling and suspension in Ride magazines Rider Power Survey,[2] Triumph's Daytona 675 was second in the same category.
