2017 Dorsoduro 900

Dorsoduro 900 is born out of Aprilia's solid tradition in this motorcycle segment and it is a true thrill generator. The exclusivity is also due to its original and innovative technical choices, like the mixed steel trellis/aluminium plates frame with excellent handling and tight cornering characteristics. The 90° V-twin engine puts a smile on the rider's face every time the throttle is twisted, thanks to the new characteristics of maximum torque and power that amplify its personality. The fine electronic management that includes, besides the Ride-by-wire multimap accelerator, traction control and ABS, complete the technical equipment on the Dorsoduro 900.

Better performance from the revamped V-twin engine

Starting from the 750 cc 90° V-twin engine base, well-known and popular because of its character and reliability, Aprilia developed a new 900 cc unit with the goal of obtaining more torque and response at low and medium rpms for a thrilling riding experience. The Aprilia V-twin was therefore revisited in numerous details to achieve this purpose. The new engine capacity was obtained by increasing the stroke from 56.4 mm to 67.4 mm and leaving the bore unchanged (92 mm). By so doing, maximum power now peaks at 95.2 HP at 8,750 rpm, but more important is the maximum torque value that goes from 82 Nm at 4,500 rpm on the 750 cc V-twin to 90 Nm at 6,500 rpm on the new 900 cc V-twin, a value that is truly at the top of its category. It should be noted that, despite the fact that maximum torque peak for the new 900 cc V-twin is reached a higher rpms, the torque curve is actually flatter and always higher than the 750 cc predecessor. This operation allowed for an increase in acceleration response and pick up, all to the advantage of riding fun, without limiting the proverbial reliability of the powerplant in any way, shape or form.

Although the architecture remains unchanged - 90 degree angle between the two cylinders, as well as a timing system with four valves per cylinder, dual overhead cam and liquid cooling - the new engine has undergone various changes: an important operation aimed at reducing friction was carried out on the pistons, completely redesigned and now characterized by a special anti-friction feature on the mantle, whereas new pins have led to a lightening of the alternated parts in motion. The crankshaft, also new, is balanced differently

A new and more efficient semi-dry carter internal lubrication circuit reduces losses of power due to shaking and keeps consumption and temperature of the lubricant to a limit, thereby eliminating the need for an oil radiator. The engine also uses new injectors: improved fuel/air mixture spray achieved through the increase of fuel pressure benefits consumption and emissions, thereby contributing to the engine's compliance with the limits established by the Euro 4 emissions standard. This result is also achieved thanks to the exhaust system, fitted with a double oxygen sensor. The Aprilia Dorsoduro 900 engine is also fitted with an automatic decompresser which makes it easier to start in low temperature conditions.

The load on the clutch lever has decreased by 15%, all to the advantage of comfort with a clutch that has been completely revamped in all of its components, whereas the primary drive reduction ratio has been changed to optimize exploitation of the available power. Aprilia Dorsoduro 900 is also available in a limited-power 35 kW version, ideal for newly licensed riders.

New electronic management

Electronic engine management is now handled by the new and more powerful Marelli 7 SM ECU, the same hardware used on the V4 bikes from Noale, that dialogues with the new full Ride-by-wire electronic accelerator system, completely built into the throttle grip. This system allows even more accurate management of the fuel/air mixture and the injection throttle valve opening based on numerous parameters including engine speed, gearbox position, air flow (in quantity and speed), throttle grip and temperature, with great benefits in terms of smooth riding without opening/closing jerks, containment of harmful emissions and fuel consumption. The engine is, therefore, always able to distribute the ideal torque and provide the best acceleration, all to the advantage of a satisfying and fun ride. The system also allows a weight reduction of 550 grams compared to the previous Ride-by-wire that equipped the Dorsoduro 750. The sophisticated electronic management also provides the possibility of changing the engine mapping, radically changing the character of how the power it is capable of developing is unloaded onto the ground. The Sport setting provides an immediate and aggressive throttle response; the Touring logic provides a smoother response, ideal for touring and daily use, whereas the Rain map reduces available power to about 70 HP and is therefore ideal in the event of difficult weather conditions or on slippery road surfaces. Mapping can also be changed at any time, even on the fly, by simply pressing the engine start button.

Dorsoduro 900 introduces a new Aprilia traction control system with sensitivity adjustable to three levels (it can also be disabled) to limit rear wheel spin by acting on ignition and the injection throttle valves. The Dorsoduro 900's Aprilia Traction Control system is combined with a Continental two-channel ABS system with developed calibration in order not to take anything away from the sporty ride. The ABS feature can also be disabled. The new electrical system places the engine control and management systems in communication with the new colour TFT digital instrumentation. The compact unit with a 4.3-inch screen contains a wealth of information that is always highly legible thanks to its capacity of adapting the background and font colours based on the conditions detected by the light sensor. The information displayed includes: rev counter, speedometer, selected gear indicator, coolant temperature, selected engine map and clock. Using the practice MODE joystick on the new left hand electrical block, you can navigate through the menu and scroll/adjust the following parameters: odometer, traction control level, ABS ON (only when not in movement), MENU (only when not in movement), Trip A, Trip A time, Trip A maximum speed, Trip A average speed, Trip A average consumption, Trip B, Trip B time, Trip B maximum speed, Trip B average speed, Trip B average consumption, instantaneous consumption, Km ridden in reserve.

One of the optional features is the AMP installation kit, the Aprilia multimedia platform that connects a smartphone to the vehicle to provide an exceptional quantity of information useful for the ride: the new instrumentation lets you view all the data related to incoming/current calls on the screen, as well as information related to the use of an intercom or any audio files that you may be playing.
