The Triumph Street Triple is a naked or streetfighter motorcycle made by Triumph Motorcycles, first released towards the end of 2007.[1] The bike is closely modelled on the Speed Triple 1050 but uses a re-tuned inline three cylinder 675 cc engine from the Daytona 675 sport bike, which was released in 2006.[1][2]

History[edit]

First generation Street Triple
2014 Street Triple R with slanted headlights and low-mounted exhaust

A number of spy photos and speculated design shots were reported in the motorcycle press,[3] with one magazine capturing a road test of the completed Street Triple.[4] Later articles reported on leaked design shots of the new bike.[5] A report on the showcasing of the finished bike to dealers was published on 6 March 2007, along with a spy video of a test ride.[6]

The Street Triple R shares the same engine and chassis as the standard model but has fully adjustable suspension both front and rear which is shared with the Daytona. The revised rear suspension results in a slightly higher seat height over the standard model and sharper rake. It has other minor equipment differences over the standard bike in the way of handlebars, brakes, and different colour schemes.

In 2010, Triumph launched the Tiger 800 and Tiger 800 XC, which use a longer stroke version of the Street Triple engine.[7]

The Street Triple's circular headlights were changed to an angular shape for the 2012 model year. In 2013, Triumph remodeled the frame, making the bike both lighter and more agile. The engine remained unchanged while the 1st gear was made considerably taller by taking the gear ratios from the Daytona 675. Total mass was reduced by 6 kg. A new exhaust mounted underneath the engine replaced the underseat exhaust from the previous version, moving the centre of mass forwards and down. .[8] In February 2015 Triumph will be releasing a new Street Triple Rx, with the angular seat unit from the Daytona 675, and different colors.[9]
