Description and history of motorcycles Triumph Street Triple

The Triumph Street Triple, a standard motorcycle produced by Triumph Motorcycles since 2007, is intricately designed based on the Speed Triple 1050. It features a re-engineered inline three-cylinder 675 cc engine, derived from the Daytona 675 sport bike that debuted in 2006.

In 2007, the motorcycle press buzzed with spy photos and speculative design sketches, with one publication even capturing a road test of the finished Street Triple. Subsequent articles revealed leaked design images, and on March 6, 2007, a report surfaced showcasing the completed bike to dealers, accompanied by a spy video of a test ride.

First generation (2007-2011)

The Triumph Street Triple was officially introduced in 2007, stepping in to fill the void left by the 600 Speed Four. It adopts the design language of modern Triumph naked bikes, which was first established with the Speed Triple in 2005. This includes high-mounted twin mufflers and dual circular headlights, complemented by a dashboard unit positioned atop the front end. A notable distinction of the Street Triple is its conventional swingarm, contrasting with the single-sided swingarm found on the Speed Triple. Many components are shared with the Triumph Daytona 675, particularly evident in the frame and swingarm. The 675cc three-cylinder engine, borrowed from the Daytona 675, has been re-tuned for a more street-friendly performance, making it suitable for daily riding while delivering an impressive output of 79 kW (106 bhp) at 11750 rpm. Triumph opted for a new naming convention for this model, avoiding a straightforward displacement addition to the Speed Triple name, thereby marking its distinct place in Triumph's history.



In 2008, Triumph unveiled the Street Triple R, which shares the same engine and chassis as the standard model but boasts fully adjustable suspension at both the front and rear, inherited from the Daytona. This revised rear suspension results in a slightly elevated seat height compared to the standard version and a sharper rake angle. The front brake system is also taken from the Triumph 675 Daytona, featuring a fully radial Nissin setup, including the master cylinder and calipers. Additional minor upgrades differentiate it from the standard model, including variations in handlebars, seating, and color options, notably matte orange and matte grey.



In 2010, Triumph introduced the Tiger 800 and Tiger 800 XC, which utilize a longer stroke version of the Street Triple engine.

Second generation (2011-2012)

For the 2012 model year, the Street Triple's iconic circular headlights were replaced with an angular design, aligning with the new aesthetic of modern naked models, a change first seen in the 2011 Speed Triple 1050. This shift sparked controversy, as the circular headlights had been a hallmark of modern naked bikes since 1997, earning the new iteration the nickname "bugeye" due to its insect-like appearance. Other cosmetic alterations included redesigned side casings, a brushed aluminum finish around the exhaust, black rear sets, and updated graphics. Importantly, these changes were purely aesthetic; the engine and mechanical components remained unchanged.

Third generation (2013-2017)

In 2013, Triumph revamped the Street Triple's chassis, introducing a new frame constructed from aluminum but with fewer components and welds. The caster angle was adjusted from 24.3° to 24.1°, and the previous tubular sub-frame was replaced with a new aluminum cast sub-frame. A significant modification was the relocation of the exhaust to a position beneath the engine, replacing the underseat exhaust from the prior model, which shifted the center of mass forward and downward. The bike also received lighter rims, contributing to a total weight reduction of 6 kg, making it the lightest iteration of the Street Triple. While the engine specifications remained unchanged, the first gear was notably lengthened by adopting the gear ratios from the Daytona 675. This generation also introduced new suspensions, brake discs that could be paired with a multi-mode disengageable ABS, a coded key, increased storage space under the seat, an updated dashboard featuring a fuel gauge, improved finishes, new mirrors, and subtle modifications to the tank base.



The Street Triple R featured a red sub-frame and a narrower caster angle, reduced from 23.9° to 23.4°. The R model retained its distinctiveness with a 19 mm radial master cylinder and radial four-piston brake calipers paired with 310 mm discs. Its suspension system, comprising a 41 mm inverted fork and a separate reservoir shock, offered adjustability for rebound, compression, and preload. An optional disconnectable and configurable feature was also available.



In February 2015, Triumph launched the Street Triple Rx, based on the R model, which included the angular seat unit from the Daytona 675, a quick-shifter, and unique color options with red rims across all schemes.

Fourth generation (2017-present)

In January 2017, Triumph announced the replacement of the 675 cc Street Triple with a new lineup of 765 cc models, officially launched as 2018 models. Despite the increase in engine capacity by 90 cc, the new models are slightly lighter than their 675 cc predecessors, maintaining compact engine casings. This generation features four variants: the base model S, the mid-range R, and the high-spec RS. Consistent with earlier models, the headlight design is shared with the 2016 Speed Triple.



Each model offers varying levels of equipment, including differences in brakes, suspension, and the inclusion of a quick shifter, along with distinct power outputs: 113 hp (84 kW) for the S, 118 hp (88 kW) for the R, and 123 hp (92 kW) for the RS. Additionally, a 660 cc version of the S has been made available for the UK's A2 license. Triumph also introduced a Low Ride Height (LRH) variant of the R model, which lowers the seat height to 780 mm by adjusting the front stroke, shortening the rear shock, eliminating rebound adjustment, and modifying the seat profile, while retaining all other features of the R model.



In 2020, the Street Triple underwent a mid-cycle update. The more track-oriented RS version received minor adjustments to the intake and exhaust without changes to power output, alongside cosmetic updates to the mirrors and headlight. A new lower seat height option was introduced, featuring a different seat and modified suspension. The 2020 model was homologated by the FIM for the World Supersport Next Generation class in 2022.



In 2023, both the R and RS versions were upgraded with a more powerful engine outputting up to 130 horsepower, shorter gearing, higher-spec Brembo Stylema brakes (exclusive to the RS), and refined chassis geometry that raised the rear, reducing the wheelbase, rake, and trail for sharper handling. For the first time, IMU-based cornering ABS and traction control were introduced. The R model now features a full-TFT instrument cluster, albeit smaller than the RS’s 5-inch version, while the fuel tank capacity was reduced by 2.4 liters to 15 liters. A new limited-edition Moto2 version was also launched, equipped with clip-on handlebars and additional track-oriented enhancements.
