Overview

Your Street Triple: do you want it spicy or decaffeinated? In either case, the urge to take it full throttle is pressing. No sweeteners or bitterness for the 765 RS version; just sport in every whiff.

For this 660 S, it’s something else entirely. The body plays the same seduction score, but at startup, you enter a less intense, more accessible world. Where the English roadster presents its tributes before warming your hands.

The Hinckley manufacturer knows how to handle the personality of its machines. Observe, compare, detail, and count on a short list the differences in appearance between the S and the RS. None of the owners will feel like they have a stripped-down Street. Sharing the same fierce gaze, an identical line, the same athletic frame, and virulence just as exciting, the "nice" one of the family is confusingly close. Above all, it exudes improvement, modeled on the upgrade of the 765.

You have to have a keen eye to grasp the subtleties, its effects that take you from standard to sporty. Here, no engine guard or seat cowl; the metallic appearance of the rear subframe has faded; the carbon fiber finish on the exhaust tip is gone; the mirrors take a classic position; the equipment list confirms the gap between the sisters.

The Street Triple S costs less, much less, than the top of the range. It must be said that its power is lower. 95 horsepower, a reduction of about 30%. Several reasons for this. First, it needs to be accessible to A2 license holders. To be restricted, it must be capped at 70 kW. Second, it doesn't have the same engine, even though it's a three-cylinder. The 660 cm3 engine has adapted to meet Euro5 standards and already enjoys sufficient power to go fast.

On the chassis side, we also review the ambitions. No bleeding attacks in sight? No need to take back the Brembo M50 four-piston brake calipers. More measured two-piston Nissin calipers will handle the 310 mm discs. The suspensions lose almost all of their adjustments; only the Showa shock absorber retains the possibility of adjusting preload. The Japanese manufacturer also provides the 41 mm inverted fork.

One of the visual strengths, perhaps the most important, is this double optic, more intense and modified in each chapter. Behind it, the dashboard is modern but from another time. A liquid crystal digital window cohabiting with a monocle where a needle agitates for the tachometer. It was perfect for the 675 Street Triple – it’s less classy and far less technological in the era of the 765. Should we complain about it at a time when TFT screens invade everything? Not really... not relevant rather. Because the 660 Street Triple S is there to introduce you to the gang of hairy roadsters. Discovering also means settling for a portion when the premium offers the cake. This applies to the on-board electronics; although they are not crumbs, far from it. This 660 S has traction control, ABS and two Riding Modes (Road or Rain), LED lighting, and the same daytime signature as the RS.

The Triumph Street Triple S was available in two versions in its previous generation: 765 cm3 to be part of the family and 660 cm3 to cater to young license holders. The descendant simplifies things. The small displacement for the boys, the mid-size for the bads. The choice of colors is also reduced to the essentials: one. White, and that's it. This "small" Street Triple also distinguishes itself from its predecessor by a surprise of the most interesting kind. It’s less expensive, without qualms. However, its greatest threat could come from its own tribe: the 660 Trident will not hesitate to steal its market share.

Is that why this Street is quietly making a getaway? In any case, it will no longer be manufactured from September. Goodbye, miss Triple. The R and S ladies will continue to make the category tremble.
