Aprilia Dorsoduro 900 2017-2020 Service Manual

Motoryk's own owner-focused review captures the Dorsoduro 900's whole appeal in one line: "the chassis is tight and communicative, and the Brembo brakes are class-leading for this segment. It's a proper hooligan tool dressed in Italian clothes." MCN's own review agrees this is a genuine niche machine, and no less appealing for it — "if you are into big supermotos, the Aprilia is well priced, has a high spec and rides with a spark of attitude that its naked sibling, the Shiver 900, lacks."

Power comes from an 896cc liquid-cooled 90-degree V-twin, a stroked-out version of the 2007 Shiver 750's engine — Wikipedia's own spec sheet confirms the stroke grew from 56.4mm to 67.4mm specifically to meet Euro 4 emissions standards while boosting displacement. Cycle World's own launch coverage notes the reworked engine deliberately prioritizes "torque and responsiveness in the low to midrange" over outright top-end power, delivering a claimed 95.2 hp at 8,750 rpm and 66.4 lb-ft of torque at 6,500 rpm — Cycle World's own in-house dyno testing measured a real-world 83 hp at 8,990 rpm and 56.38 lb-ft at 6,000 rpm, a genuine reminder that claimed crank figures and rear-wheel dyno numbers rarely match exactly.

A genuine first for the Dorsoduro line arrived with this generation: a ride-by-wire throttle system, controlled by the Marelli IAW 7SM ECU, enabling three selectable engine maps and three-stage traction control — features the earlier 750 and 1200 Dorsoduro models never had. New three-spoke aluminum alloy wheels saved a genuine 2.4kg (5.4 lbs) of rotating mass over the previous design. MCN's review found the chassis genuinely confidence-inspiring through bends — "not super-agile, but assured," with adjustable suspension that lets riders dial out the rocking sensation common on long-travel supermotos, and both traction control and ABS fully deactivatable for riders wanting to push harder. The steel tube frame with aluminum subframe plates carries dual 320mm front discs with 4-piston Brembo calipers and a 240mm rear disc, contributing to a dry weight of 195kg (430 lbs) and a 12-litre fuel tank. Motoryk's own maintenance notes flag a genuine known issue worth checking on used examples: throttle body carbon buildup, which can cause rough idling and stumbling below 3,000 rpm — along with verifying service history on 2017-2018 models specifically, since early units had some ECU mapping quirks Aprilia dealers addressed under warranty. Cycle World's own buyer's guide confirms the Dorsoduro 900 saw only graphic updates after its 2018 model year, meaning the mechanical package stayed consistent through the end of production around 2020.

This factory service manual covers the procedures, torque specs, and diagrams needed to keep a 2017-2020 Dorsoduro 900 running the way it was built to.
