2017 Dorsoduro 900
The fun bike from Aprilia evolves with the sole objective of providing maximum riding fun. More performance from the revamped twin-cylinder engine, a tighter ride and better handling from the refined chassis architecture and the best available technology.
Aprilia Dorsoduro is the fun bike par excellence. Born out of an ingenious intuition by Aprilia, it was built with the sole objective of providing the most possible road riding fun, drawing from the best characteristics of sport bikes and the best characteristics of supermotards. The result is a bike with advanced technical solutions, agile and with performance at the top of its category. A truly special bike, achieved not only thanks to Aprilia's skills in packaging particularly efficient chassis architectures combined with high performance powerplants, but also thanks to collaboration with the Aprilia Racing Department, capable of earning a total of 54 world titles in the most difficult and selective competitions where they have participated, 7 of which in the world Supermoto championship.
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 8.4 kgm (82 Nm) at 4,500 rpm on the 750 cc V-twin to 9.17 kgm (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 change allowed the acceleration response to be increased, all to the advantage of a fun ride, without limiting in any way whatsoever the proverbial reliability of the powerplant, that in any case, now benefits from a new internal lubrication circuit capable of limiting power loss due to churning and lubrication consumption. The exhaust system, fitted with a double oxygen sensor, contributes to bringing the engine to within the limits established by the Euro 4 pollution standard.
New electronic management
Electronic engine management is now handled by the new and more powerful Marelli 7SM ECU 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 is ideal in the event of difficult weather conditions or on slippery road surfaces. 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 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. 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.
