Triumph announce new Street Triple S

The Triumph Street Triple range has been joined by the A2 licence friendly Street Triple S

Triumph Street Triple S (2020)

TRIUMPH have announced the new 2020 Street Triple S, which gains updated bodywork, a revised Euro5 compliant exhaust and, of course, the same headlight and bodywork styling as the 2020 Triumph Street Triple RS.

Triumph Street Triple S Pricing and colours

The new Street Triple S is available for £7,900. The 2020 Street Triple S is available in Crystal White, with Diablo Red and Black decals, black tank badges and a textured black rear sub-frame.

The biggest change to the Street Triple S for 2020 is the newly styled and distinctive headlights. Gone are the slightly bulbous units of before, instead the new machine has a distinctly angrier face, with LED daytime running lights framing the new front end. The new lighting system is also claimed to be brighter than before thanks to improved positioning.

The bike has also gained the more angular bodywork worn by the range-topping Street Triple RS, with the headlight cowl, side panels, and seat unit all being updated for the 2020 version of the machine.

Beneath the skin, the new model is very much the same as the outgoing Street Triple S, although some work has been done to get the machine through the ever-tightening EU emissions regulations. On that note the team at Hinckley have re-designed the exhaust system of the new bike, creating a bike that “delivers an even richer, deep Triumph triple roar with an exciting induction sound on acceleration”.

The bike features switchable riding modes, Road and Rain, with the throttle map and traction control system adjust accordingly.

Performance-wise the new bike is identical to the old machine in that it produces 35kW (47hp) peak power and 60Nm (44.2ft-lb) peak torque in A2-license compatible format. Once a rider has completed their training and testing for a full A (unrestricted licence), the machine can be de-restricted by a triumph dealer. In this form, the bike is claimed to produce 70kW (95hp) at 11,250rpm and full peak torque of 66Nm (48.6lb-ft) at 9,250rpm.

Chassis components for this year are provided by Showa, supplying 41mm SF Forks and a pre-load adjustable piggyback reservoir rear shock, and Nissin with twin sliding calipers up front. The rear caliper is a Brembo unit and ABS fitted as standard.
