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.
