The Triumph Street Triple was a naked motorcycle made by Triumph Motorcycles Ltd in 2007. The bike was similar to the Speed Triple 1050 and was manufactured over four generations. The first generation debuted from 2007 to 2011, the second from 2011 to 2012, the third from 2013 to 2017, and the fourth from 2017 to the present.
In 2013, the British motorcycle manufacturer launched the Triumph Street Triple, a naked motorcycle in its seventh year of production and part of the third generation. The bike came in 2013 with a host of modifications.
The bike was built on a remodeled chassis with a new aluminum frame unit with fewer parts and welds. The most notable feature was the exhaust system, no longer mounted under the seat but underneath the engine, moving the center of mass forward and down.
Also, the bike rolled on lighter wheels, making the motorcycle lighter and more agile. After all modifications, the bike lost six kg (13 lbs), resulting in the lightest generation of the Street Triple machines.
The 2013 Triumph Street Triple had underneath its fuel tank the same 675cc four-stroke three-cylinder liquid-cooled engine as the previous model, delivering 106 hp at 11,850 rpm and 68 Nm (50 lb-ft) torque at 9,750 rpm.
Also, the bike packed the same six-speed manual transmission with a wet multi-plate clutch and a final O-ring chain drive, the only difference being the first gear made taller by taking the gear ratios from the Daytona 675 model.
