For the 2017 model year, the Aprilia Dorsoduro 750 gets an upgrade to 900cc, making it the 2017 Aprilia Dorsoduro 900. Aprilia says that the new 896cc 90° v-twin engine is a stroked out version of the 750cc motor (from 56.4mm to 67.4mm), which allows Aprilia to meet Euro4 emission standards while also giving the Dorsoduro 750 a much-needed upgrade.
Despite the 150cc increase in displacement, the 2017 Aprilia Dorsoduro 900 makes only an additional 3hp, with peak power now set at 95hp at 8,750 rpm.
While that change in horsepower is underwhelming, there is somewhat better news to be found in the torque curve, which sees a 6 lbs•ft torque increase, for 66 lbs•ft at 6,600 rpm.
Aprilia says that the torque curve for the Dorsoduro 900 is flatter than that of Dorsoduro 750, and at all rpm points higher. That is at least modestly reassuring.
