New Triumph Street Triple Debuts with 765cc Engine

As expected, today we get to see the 2017 Triumph Street Triple, with its new engine capacity: 765cc. The new engine displacement comes from both an increase in bore and stroke on the iconic three-cylinder motor, with Triumph using a new crank, pistons, and barrels in its construction.

Three flavors of Triumph Street Triple will be available for 2017, with S, R, and RS-spec (above) machines being available, with obvious performance differences existing between the trim levels.

As such, peak horsepower will be 113hp (S), 118hp (R), and 123hp (RS) – a notable boost over the 675cc machine’s 105hp. Meanwhile, peak torque has been improved from 50 lbs•ft, now to 53 lbs•ft (S) and 56 lbs•ft (R & RS).

All the models tip the scales at 166kg (dry) according to Triumph, which is a 2kg reduction over the outgoing model.

The bump in displacement is surely a result of two factors: 1) the tightening emissions controls in Europe, which have seen manufacturers bumping bikes up in displacement to hit horsepower goals, and 2) a response to the burgeoning middleweight streetfighter market, which is moving to engine sizes that are closer to 800cc in displacement.

Adding some refinement to the smaller streetfighter, Triumph has included a TFT dash on the R & RS models, as well as a slipper clutch. The RS model sees the addition of a quickshifter.

The Triumph Street Triple RS also comes with higher spec components, including fully adjustable Showa big-piston forks (BPF), Öhlins TTX 40 shock, and Brembo M50 four-piston caliper brakes up front. The Street Triple RS includes five riding modes on its ride-by-wire system.

Meanwhile, the Triumph Street Triple R only gets four riding modes, and sees its go-fast components speced-down to separate-function Showa big-piston forks (SF-BPF), a Showa rear shock, and Brembo M4.32 four-piston calipers.

The Triumph Street Triple S makes do with two riding modes, separate-function Showa forks (SFF), a preload-adjustable Showa rear shock, and two-piston front brakes.

The 2017 Triumph Street Triple will start at $9,900 MSRP in the USA ($11,200 in Canada) with the S-spec model, and go on up from there.
