The Triumph Street Triple was a naked or streetfighter machine made by the British motorcycle manufacturer Triumph. The bike was released at the end of 2007 and was similar to the larger 1,050cc Speed Triple 1050. Instead, the smaller machine packed a retuned version of the three-cylinder engine used on the Daytona 675 sports machine.
The bike was released in 2007 as a replacement for the 600cc Speed Four and shared the design of modern Triumph naked motorcycles, introduced on the Speed Triple in 2005, such as a high-mounted exhaust system, twin round headlights, and an instrument panel mounted on top of the lights.
The 2007 machine was part of the first generation, which comprised models manufactured from 2007 to 2011. A notable difference of the Speed Triple was represented by the conventional swingarm. It also shared many parts with the Daytona 675, mainly observable on the frame and swingarm.
In the visual department, the bike was fitted with standard features, such as a twin headlight system, a small fly screen, a one-piece dual seat, an under-seat-mounted exhaust system, a side stand, and five-spoke lightweight wheels.
The 2007 Triumph Street Triple had installed underneath its fuel tank a 675cc four-stroke three-cylinder liquid-cooled engine managed by a fuel injection system, delivering 108 hp with maximum strength at 11,700 rpm and 69 Nm (51 lb-ft) torque at 9,100 rpm.
