TRIUMPH Street Triple S (2017-2021) Specs, Performance & Photos

In 2017, the British motorcycle manufacturer announced that they would replace the 675cc Triple with a new 765cc powered Street Triple motorcycle, released to the public in 2018.

Although the engine had 90cc more than the previous models, it weighed less than the first and second-generation motorcycles. The fourth generation had three models in the line-up, including the standard S, intermediate R, and the RS, which had higher specifications.

The 2017 Triumph Street Triple S was fitted with standard features, such as a dual headlight system with a small fly screen, a two-piece double seat, an under-belly exhaust system, a side stand, and five-spoke lightweight wheels.

The bike was built on an aluminum beam twin-spar frame with a 41 mm Showa upside-down telescopic fork on the front with 110 mm wheel travel and a preload-adjustable Showa shock absorber on the rear with 124 mm wheel travel.

As for braking, the bike packed two 310 mm floating discs with two-piston Nissin calipers on the front wheel and a 220 mm fixed disc with a single-piston Brembo caliper on the rear wheel, offering excellent stopping power.

As for the power figures, the 2017 Triumph Street Triple S had its soul brought to life by a 765cc four-stroke three-cylinder liquid-cooled engine that delivered 111 hp with a peak force at 11,250 rpm and 73 Nm (54 lb-ft) torque at 9,100 rpm.

In 2023, the bike was available in Phantom Black with an MSRP starting at $10,150 and Diablo Red starting at $9,900.
