presentation of the 660 Street Triple S 2021
Do you want your Street Triple full-bodied or decaffeinated? In either case, the urge to take it boiling hot is pressing. No sweetener or bitterness for the 765 RS version; just sport in every whiff.
For this 660 S, it's something else. The body plays the same seductive score, but when you get going, you're in a less dry, more accessible world. This is where the British roadster pays its respects before warming your hands.
The Hinckley-based manufacturer knows how to handle the personality of its machines. Observe, compare, detail, and count the differences in appearance between the S and the RS on a short list. None of the owners will feel like they've got a Street on the cheap. Sharing the same patient look, identical lines, equally athletic skeleton and equally exciting virulence, the "gentle" member of the family is confounding in the extreme. Above all, it exudes improvement, modelled on the 765 upgrade.

The Street Triple S costs less, much less than the top of the range. It has to be said that its power output is lower: 95 hp, a discount of around 30%. There are several reasons for this. Firstly, it's designed to pass A2 driving tests. In order to be bridled, it has to be limited to 70 kW. Secondly, it doesn't have the same engine, even though it's a three-cylinder. The 660 cm3 block is now Euro5-compliant, and is already powerful enough to go fast.
As for the chassis, we've also revised our claims. No bleeding attacks in sight? No need to use Brembo M50 4-piston brake calipers. More measured Nissin 2-piston calipers will take care of the 310 mm discs. The suspension loses almost all its settings; only the Showa amorto retains the possibility of adjusting preload. The Japanese manufacturer also supplies the 41 mm inverted fork.

Discovering also means settling for a slice when premium offers the cake. That goes for the on-board electronics, although they're far from crumbs. This 660 S has traction control, ABS and two driving modes (Road or Rain), LED lighting, and the same daytime running light signature as the RS.
The previous generation of the Triumph Street Triple S was available in two versions: 765 cm3 to be part of the family, and 660 cm3 to satisfy the demand for a young licence. The descendants simplify things. Small displacement for the boys, medium for the bads.
The choice of colors is also reduced to the essentials: just one. White and that's it.
This "little" Street Triple is also distinguished from its predecessor by a most interesting surprise. It's less expensive, with no qualms or qualms. However, its biggest threat could come from its own tribe: the new 660 Trident won't be shy about taking its share.

Anyway, to talk about this little monster I bought in March 2020, I'm just delighted with it. For 35kw in the sporty roadster category, I think it outperforms its rivals. With its three-cylinder engine, it develops plenty of torque at low revs, and surprisingly long in the first three gears for a flanged car. Rating : 5/5 Respond to S_Triple
