Triumph Motorcycles introduces a revised Street Triple family for 2017, featuring a larger 765cc engine based on its previous design Inline Three design (675cc). There will be three iterations of the Street Triple, the baseline S model alongside a higher spec R model (which will also be available in a low ride height version) and a premium RS model. The Street Triple family will start with a $9900 MSRP in the US and be available in late March/early April.
Powerplant and Transmission
The new liquid-cooled, 12-valve DOHC 765cc Triple boasts 80 new parts according to Triumph, including new pistons, crank, Nikasil-plated aluminum barrels and larger bore and stroke (78 x 53.4mm compared to last year’s Street Triple which featured a 74 x 52.3mm design).
All three Street Triple models carry the same basic engine architecture, but set-up and ECU settings are tailored to provide a different experience on each bike. The S model has 111 horsepower available at 11,500 rpm and 53.8 lb-ft torque at 9100 rpm. The R provides more pep thanks in part to a different crankshaft, offering 115 horsepower at 12,000 rpm and 56.8 lb-ft torque at 9400 rpm. Finally, the RS raises power 16% compared to last year’s model and torque by 13%, with 121 ponies available at 11,700 rpm and 56.7 lb-ft at 10,800 rpm.
Each has a revised stainless steel 3-into-1 exhaust with a low-slung silencer along with an updated airbox, improving the sound quality of intake and exhaust notes according to Triumph.
All have a six-speed gearbox and wet, multi-plate clutch. The R and RS models, however, come with slip and assist functionality whereas the S does not. The RS also features a quickshifter.
Chassis and Dimensions
Triumph introduces a new dual-sided, cast aluminum alloy gull-wing swingarm on all three 2017 Street Triples to improve stability at higher speeds. The main frame on all three is a twin spar aluminum design with a two-piece high-pressure die-cast rear section.
Suspension updates differ model to model. The Street Triple S comes with a 41mm inverted separate function Showa fork with 4.3 inches travel and a Showa piggyback reservoir shock with stepped preload adjustment and 4.8 inches travel.
The Street Triple R is suspended by a 41mm, inverted Showa separate function big piston fork with adjustable compression and rebound damping and preload. There’s 4.5 inches travel available at the front. The rear shock is a Showa piggyback reservoir unit with adjustable spring preload, compression damping and rebound damping. Riders will have 5.2 inches travel to play with at the back of the R model.
At the top of the heap is the RS, which utilizes a 41mm inverted Showa big piston fork with 4.5 inches travel and adjustable compression and rebound damping and preload. The rear shock is an Ohlins STX40 piggyback reservoir unit with 5.2 inches travel and adjustable spring preload along with compression and rebound damping.
Each rolls on 3.5-inch by 17-inch cast front wheels and 5.5-inch by 17-inch cast rear wheels. Pirelli Diablo Rosso Corsa tires are featured on both the S and R models while the RS comes with Pirelli Diablo Supercrosa SP rubber.
Triumph lists the dry weight, which for all three models is a claimed 365 pounds. Each comes with a 4.6 gallon fuel capacity and the S features a seat height of 31.8 inches, while the R and RS are a little taller at 32.5 inches.
All three models share the same rear brake set-up, a single 220mm fixed disc pinched by a single-piston Brembo sliding caliper. The front set-up is where things get a bit different.
The S model features twin 310mm floating discs with Nissin, two-piston calipers. The R comes with twin 310mm floating discs and Brembo M4.32 four-piston radial monobloc calipers. The RS has Brembo hardware at the front too; M50 four-piston radial monobloc calipers and twin 310mm floating discs.
Triumph dialed-in the electronics and instrumentation on its new Street Triples as well. The R and RS models come with new, five-inch, full color adjustable TFT instrument displays. These have three different screen display styles to choose from and with different contrast levels to make it easier to see the readout in a variety of lighting conditions. The S model is a simpler design with a speedometer, tachometer, ride mode, gear position, fuel gauge, odometer, trip meter and trip distance display. The R and RS models have all this information also, but also come with two trip displays, range to empty, service information, coolant temperature and, on the RS only, a lap timer.
All three have ride-by-wire and ABS. The R and RS, however, have switchable ABS. Each machine also comes with a number of ride models that link together with the ride-by-wire, ABS and traction control settings. The S comes with two ride modes: Road and Rain. The R has four: Road, Rain, Sport and Rider Programmable. The RS has five modes: Road, Rain, Sport, Rider Programmable and Track.
Traction control is managed on the S model through the two ride modes, but on the R and RS riders can determine the level of traction control through the rider programmable mode, choosing from either rain, road, track, sport or off TC settings.
The R and RS also come with a new five-way joystick to allow riders to navigate the swath of electronics choices. The S model comes with a revised cubes set-up taken from the most recent Speed Triple.
The RS also comes with a quickshifter, that allows clutchless upshifts, standard. The item can be added to the R and S models as an accessory.
Already an aggressively styled machine, Triumph’s Street Triple gets updated lines with new bodywork, fly screen, radiators, cowls and integrated air intake. The seat is changed too to give the machines a sharper look.
The S will be available in Diablo Red or Phantom Black colorways. The R will be dressed in either Jet Black, Matte Aluminum Silver or Crystal White. The RS will feature either Matte Silver Ice or Phantom Black.
There will be numerous additional accessories available from the Triumph catalog for each machine as well. Full specs and a complete photo gallery follow below.
