Triumph Street Triple 765RS 2017 Service Manual

Bennetts' own review captures a genuine journalistic about-face: "call me cynical... when Triumph claimed the new Street Triple 765 was a game changer in its marketing parade, I sniggered. Surely it's just a new Street Triple I thought? And nothing wrong with that. But a game changer? I'll eat my words." Rider Magazine's own coverage confirms the sheer scale of Triumph's brand investment here: within a lineup where eight models carry the words "Speed," "Street," or "Triple" in their name, this all-new 2017 platform genuinely redefined the top of that hierarchy, replacing the beloved 675cc engine that had powered the Street Triple since its 2007 launch.

Power comes from a 765cc liquid-cooled inline-three, DOHC with 4 valves per cylinder — Ultimate Motorcycling's own technical breakdown confirms this isn't a completely new engine but a comprehensively reworked version of the Daytona 675's motor: "receiving a healthy increase in bore and stroke, the 765 has a new crankshaft, pistons, con-rods, balancer shaft, and opted for Nikasil-coated aluminum barrels," with over 80 new components total. On the range-topping RS specifically, this delivers a claimed 121-123 hp at 11,700-10,800 rpm and roughly 57 lb-ft of torque, MCN's own review confirming genuine gains across the board: "despite producing 13% more torque, 16% more power" than the outgoing 675cc engine. All three tunes across the S/R/RS lineup share a lighter, freer-flowing exhaust, revised airbox, shorter first and second gear ratios, and a new slip-and-assist clutch — genuine mechanical refinement layered consistently across the family, with each tier tuned individually via ECU mapping for its specific mission.

The RS distinguishes itself with genuinely premium hardware: MotoPlanete's own detailed spec breakdown confirms a 41mm Showa BPF inverted fork paired with an Öhlins STX40 rear shock — both fully adjustable — plus Brembo M50 monobloc front calipers, a standard quickshifter, and Pirelli Diablo Supercorsa SP tires, all riding on a steeper 23.9-degree steering head angle (versus the base S's 24.8 degrees) for sharper turn-in. Ultimate Motorcycling's own coverage confirms genuine ride-by-wire electronics arrived for the first time on this platform, with up to five riding modes on the RS, a gullwing rear swingarm, and a 5-inch TFT instrument panel — all while the whole family shed roughly 4.5 lbs versus the outgoing 2016 model despite the added technology. Rider Magazine's own testing found the RS's power delivery genuinely well-judged for real-world riding: "enough for a hair-on-fire 140 mph down the front straight of Catalunya, but not so powerful or aggressive that I ever feared... the thing would fling me off." 2017 US pricing for the RS started at $12,500, positioned as Triumph's genuine flagship naked sportbike above the lower-spec S ($9,900) and R models sharing the same fundamental engine architecture.

This factory service manual covers the procedures, torque specs, and diagrams needed to keep a 2017 Street Triple 765 RS running the way it was built to.
