Triumph Speed Triple RS 1050 2018-2020 Service Manual

Bikesales.com.au's own launch review confirms exactly what genuine engineering pedigree underpins this generation: "interestingly the current 1050cc three-cylinder engine first saw action in 2005, where it still remains in play today. Sure, it's been updated, but the fact it's so good is a testament to the engineers who breathed life into it in the first place." MotoParts Store's own detailed review confirms just how substantial the 2018 refresh's engine work genuinely was despite that long pedigree: "at the heart beats Triumph's 1050cc inline-three, now featuring 104 new components over previous generations."

Power comes from a 1,050cc liquid-cooled 12-valve inline-three, a 79mm x 71.4mm bore and stroke, and a 12.9:1 compression ratio, delivering a claimed 148-150 hp at 10,500 rpm and roughly 86 lb-ft (117 Nm) of torque at 7,150 rpm through a 6-speed gearbox with ride-by-wire throttle. MCN's own review confirms genuine real-world character across this power delivery: "the Triumph Speed Triple 1050 RS's power and torque have been increased for 2018. The delivery is smooth and effortless, yet it still has enough rush to deliver, even for dedicated sportsbike fans." MotoParts Store's own testing confirms the genuine breadth of that torque curve: "90% of peak torque arrives by 3,150 rpm — enough to blur landscapes from any gear."

MCN's own detailed comparison against the lower-spec S model confirms exactly what the RS badge buys beyond the shared engine: "the S model shares the same engine and performance as the RS. It also shares the same chassis dimensions. However, the cheaper S model runs 43mm Showa USD forks and a fully adjustable Showa rear shock. Lower spec finish, and no Arrow exhausts. The base model only gets four riding modes, missing out on the Track mode. The biggest difference is electronic: the base model has no IMU and so only gets conventional ABS and TC." MCN's own review confirms the RS's genuine dual-purpose capability once equipped with its premium hardware: "on track settings at track speeds, aggressive riding doesn't faze the Speed Triple; it remains stable and compliant, yet the steering is precise and accurate... even at a fast trackday pace ground clearance isn't an issue, the strong Brembo stoppers are consistent and offer excellent feedback."

Bikesales.com.au's own launch review confirms the RS's genuinely comprehensive standard equipment: "there are over 50 accessories available, from luggage to bling, and they are reasonably priced. Being an RS, Australian-spec Speed Triples are highly equipped from the get-go," priced at $22,700 plus on-road costs at launch. MotoParts Store's own review confirms the RS-exclusive Arrow silencers deliver a genuinely distinctive exhaust note: "these aren't mere pipes; they're megaphones for Triumph's triple-cylinder symphony, exiting stage left with stainless steel flair," while a single-sided swingarm "machined from billet aluminum" showcases the 190-section rear tire. MCN's own owner-collected reviews are consistently enthusiastic: "great bike, still modern!" — with the RS's genuinely well-rounded character summed up as "not just a naked bike... also an all-rounder capable of excelling on a daily commute and trackday alike." Curb weight sits at 189kg (417 lbs), with a 32.5-inch seat height. This exact 2018-2020 generation closed out the 1050cc Speed Triple architecture before Triumph's substantially larger 1160cc Speed Triple 1200 RS arrived for the 2021 model year.

This factory service manual covers the procedures, torque specs, and diagrams needed to keep a 2018-2020 Speed Triple 1050 RS running the way it was built to.
