The Triumph Street Triple is a naked or streetfighter motorcycle made by Triumph Motorcycles, first released towards the end of 2007.[2] 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.[2][3]
History[]
In 2007, a number of spy photos and speculative design drawings were reported in the motorcycle press,[4] with one magazine capturing a road test of the completed Street Triple.[5] Later articles reported on leaked design shots of the new bike.[6] 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.[7]
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 which were matte orange and matte grey.[8]
In 2010, Triumph launched the Tiger 800 and Tiger 800 XC, which use a longer stroke version of the Street Triple engine.[9]
The Street Triple's circular headlights were changed to an angular shape for the 2012 model year. This was nicknamed the bugeye model quickly from the bug like appearance the lights give the bike. 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. .[10] In February 2015 Triumph released a new Street Triple Rx, with the angular seat unit from the Daytona 675, a quick-shifter and different colors (where the rims are red in any color scheme).[11]
In January 2017, Triumph announced they would replace the 675 cc Street Triple with a new range of 765 cc (46.7 cu in) Street Triples. Despite having a capacity increase of 90 cc (5.5 cu in), the new models weigh slightly less than the outgoing 675 cc bike, and the engine casings are just as compact. The three models in the range are the base model S, intermediate R, and highest specification RS. As well as having different levels of equipment, such as brakes, suspension, and a quick shifter, the three models have different power outputs: 113 hp (84 kW) for the S, 118 hp (88 kW) for the R, and 123 hp (92 kW) for the RS. For the UK's A2 license, a 660 cc (40 cu in) version of the R will also be sold.[12][13]
Triumph revised the Street Triple in 2017.[further explanation needed] For 2020, the more track-oriented RS version was given minor changes to the intake and exhaust with no change in power output, and cosmetic changes to the mirrors and headlight. A 1.8 in (46 mm) lower seat height version, with a different seat and modified suspension, was added.[14][15]
Use in racing[]
Since 2019 the Moto2 class in the MotoGP world championship has been powered by the 765 cc engines from the Street Triple, replacing the engines that were previously based on the Honda CBR600RR from 2010 to 2018.
