The 2017 Triumph Street Triple range has been officially revealed, including the all-new 765cc engine which offers significantly more power and torque. Throw in a more aggressive look, a more free-flowing exhaust and an even lighter bike overall, and we’re more than a little excited.

It was 10 years ago when the Triumph Street Triple first launched. And it was a much-needed shake-up for the relatively dull naked middleweight market in 2007. Thankfully, the looks meant that there was no need to try and streetfighter a Suzuki Bandit anymore, as the Triumph had it sorted. And although the Honda Hornet was a great bike, it lacked the personality and spirit of the Street Triple. Speaking as someone who had put up with a Bandit for a while, and enjoyed the Hornet, when the Street Triple came along, I immediately knew I wanted one.
So how to change the 2017 Triumph Street Triple range after a decade?
New 765cc engine for the Triumph Street Triple:
The 2017 Street Triple S, R and RS models all share the new 765cc engine which is developed from the Daytona motor. It’s gained more than 80 new parts in the process, including new crank pistons, Nikasil-plated aluminium barrels, and an increased bore and stroke.
The result is more power low down and in mid-range, but also a peak power boost for each bike. The S version has a 6.6% increase on the old model, with 113PS at 11,250rpm, and a 7.3% improvement in peak torque with 73Nm at 9,100rpm.

The Street Triple R gets a model-specific crankshaft to get even more improvements. You’re looking at 11.3% more power with 118PS at 12,000rpm and a 13% increase in peak torque at 77Nm at 9,400rpm.
And the top spec RS is the most powerful Street Triple yet. Power is up 16% with 123PS at 11,700rpm, and peak torque boosted by 13% to 77Nm at 10,800rpm.
Those increases in engine size and power are also helped by a revised air box and a lighter, more free-flowing exhaust. You should also find it more usable with a revised gearbox geometry and shorter ratios in 1st and 2nd gear. The Street Triple R and RS models get a new slip and assist clutch for a lighter action, and the RS also gets a quickshifter (available as an upgrade option for the other two).
Controlling the power delivery is a ride-by-wire throttle, with a variety of riding modes to tailor the throttle response. The 2017 Triumph Street Triple S will allow you to choose between Road and Rain modes, while the R also gives you Sport and Rider Programmable options. Then comes the RS with the addition of a Track mode, along with a lap timer. The Street Triple R and RS can use the rider programmable modes to change the settings for the standard ABS, choosing from road, track or switching it off completely. The same mode also has the settings for the traction control, with road, rain, track and off – while riders of the S can just pick between road and rain.
Better Brakes and Suspension:
The 2017 Triumph Street Triple range all feature Showa 41mm upside-down front forks. On the S model, you get separate function forks with 110mm travel, and a stepped pre-load adjustable piggyback reservoir monoshock at the rear. And stopping comes with Nissin 2-piston sliding calipers at the front, and a Brembo single piston sliding caliper at the back.

The Street Triple R comes with Show separate function big piston front forks with 115mm travel, and the Showa piggyback reservoir monoshock. At the front are also Brembo M4.32 4-piston radial monobloc calipers, with the rear single piston sliding caliper Brembo.
And the highest specification Showa big piston 41mm front forks are saved for the Triumph Street Triple RS, with adjustable preload, rebound and compression damping. Unlike the others, it also gets an Ohlins STX40 piggyback reservoir monoshock. And the braking is provided by the Brembo M50 4-piston radial monobloc calipers controlled by a ratio and span adjustable lever, plus the Brembo single piston sliding caliper for the rear.
Lighter, More Aggressive and Agile:
The 2017 Triumph Street Triple range all feature a new gullwing rear swingarm which has better longitudinal and lateral stiffness to help the bikes remain more stable at higher speeds. The swingarm pivot position has been moved to provide less sagging at the rear under hard acceleration, and various bits of weight reduction mean that the new Street Triple is both lighter than the old one, and the lightest in class.
Both the Street Triple S and R versions come with Pirelli Diablo Rosso Corsa tyres, with the RS getting the Pirelli Diablo Supercorsa SP to cope with the higher likelihood of track use.

Then there’s obviously the changes to the bodywork. It’s all been redesigned, along with the flyscreen, radiator cowls and new integrated air take, which gives a sharper, more aggressive, nose-down look echoing the latest Speed Triples. The seat has now been restyled for a shaper, separate twin seat set-up which is still comfortable, and other details include individual colour-coded rear sub-frames for each model, new rider heal guards, and pillion footrest hangers. The Triumph Street Triple RS also gets a colour-coded belly pan, seat cowl and lower chain guard.
All models also get new displays. The Street Triple S gets a revised LCD instrument pack with rider mode selection, odometer, fuel gauge, odometer, trip meter and journey distance. The Street Triple R and RS get a new angle-adjustable 5″ colour TFT display to play with, including choosing one of the 3 (R) or 6 (RS) screen display styles, each with a high or low contrast mode. And the two higher spec bikes also get new 5-way joystick switch cubes and LED daytime running lights (DRL) which are 28 times brighter than the sidelight on the previous models. The S makes do with new LED position light headlights which are 4.6 times brighter.
Finally, there are details of the colour options for the 2017 Triumph Street Triple Range.
- Triumph Street Triple S – Diablo Red or Phantom Black (Metallic)
- Triumph Street Triple R – Jet Black (Gloss), Matt Aluminium Silver or Crystal White
- Triumph Street Triple RS – Matt Silver Ice or Phantom Black (Metallic)
Prices haven’t been announced, but obviously Triumph are already keen to point out there’s a wide range of official accessories, including Arrow exhausts and a swing arm protector kit.

Have to admit I’m pretty tempted. As I said in the article, I loved my Honda Hornet right up until the original Street Triple launched and made it seem competent still, but maybe lacking a little in personality…
Any existing Street Triple owners clamping at the bit to trade up now?
