Aprilia Dorsoduro 900 2019
The 2019 Aprilia Dorsoduro 900 Naked Bike project puts the pleasure of driving at the center of its concerns: for this reason, superstructures are reduced to the essential minimum because everything that is not essential for performance and driving pleasure has been lost. The technical elements, On the other hand, it has played a fundamental role in becoming a foundational part of the design.
More renewed Double-cylinder performance, trouble-free driving, and stronger handling is achieved by its refined chassis architecture and the best available technology. Starting from 750 ccs 90 ° V-twin engine base, known and appreciated for its character and reliability, Aprilia developed a new 900cc unit to get more torque and lower response and Average RPMs for a thrilling driving experience.
2019 Aprilia Dorsoduro 900 Naked Bike – Features
Engine
From the 750 ccs 90 ° C V-Twin engine base, well known and appreciated for its character and reliability, Aprilia has developed a 900cc unit to get more torque and response to low and medium diets for a thrilling driving experience. The cubic capacity has been obtained, increasing the stroke from 56.4mm to 67.4mm and leaving the bore unchanged (92mm). By In doing so, the maximum power now reaches 95.2 HP at 8,750 rpm, but the most important is the maximum torque ranging from 82 Nm at 4,500 RPMs on the 750 ccs V-twin to 90 Nm at 6,500 rpm on the 900cc V-twin, a value that truly is at the top of its class.
A more efficient semi-dry-sump internal lubrication circuit reduces power losses due to shakes. It maintains lubricant consumption and temperature to a limit, eliminating the need for an oil cooler. The Aprilia Dorsoduro 900 engine is also equipped with an automatic decompressor, which facilitates starting in low-temperature conditions better than 2018 Aprilia Dorsoduro. The load on its clutch lever has decreased by 15%, which is an advantage in terms of comfort with a clutch completely redesigned in all its components while reducing the main drive the ratio has been modified to optimize the exploitation of available power. Aprilia Dorsoduro 900 is also available in a limited power version of 35 kW, ideal for newly licensed riders.
Electronic
The electronic engine management is now managed by the most potent Marelli 7 SM calculator, identical to the one used on Noelle's V4 bikes, which dialogues with the complete Ride-by-wire system electronic throttle system, fully integrated with the throttle grip. This system even allows more precise management of the fuel / air mixture and the opening of the throttle valve parameters, including the engine speed, the position of the gearbox, the airflow (in quantity and in gear), throttle and temperature, with significant benefits in terms of smooth driving without opening / closing jerks, limiting harmful emissions and fuel consumption. The engine is, so always able to divide the ideal torque and provide the best acceleration, all for 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 fitted to the Dorsoduro 750.
The Aprilia Dorsoduro 900 top speed bike is equipped with the Aprilia traction control system with adjustable sensitivity to three levels (it can also be disabled) to limit rear wheel spin by acting on ignition and injection butterflies. The compact unit with a 4.3-inch screen contains a wealth of information that always very legible thanks to its ability to adapt background colors and font based on the conditions detected by the light sensor. The information displayed includes a tachometer, speedometer, selected gear indicator, coolant temperature, engine card, and clock picked. Using the Practice MODE joystick on the left power block, you can navigate the menu and calibrate these parameters, odometer, traction control level, ABS ON (Do only when not moving), MENU (only when not in motion), etc.
Frame
The executive takes advantage of the know-how developed by Aprilia in racing competitions, drawing heavily on the experience acquired on mixed structures used in the world of Supermoto championship. The upper part made of steel tube trellis (now painted red, like the saddle support frame) is associated with widely used aluminum side plates using special high-strength components bolts. The result is an outstanding rigid and lightweight structure, the best solution to take advantage of the renewed capacity of the 900cc V-twin, with an aesthetic impact that carry thin, compelling technical content and Italian futuristic.
A Kayaba fork has been installed on 2019 Aprilia Dorsoduro 900 Bike (combined with a forged aluminum steering yoke), 450 grams less including adjustable spring preload. It can withstand the stress of sporty driving and the absorption of bumps on the road, providing control aggressive driving and more comfort for more relaxed outings. The performance of the two Dorsoduro 900 suspension systems is also due to the pair of three-spoke wheels, more than 2 kg less than those of the Dorsoduro 750. The reduction of the gyroscopic effect increases maneuverability acceleration.
A sport-derived braking system complements the upper frame structure of the Dorsoduro 900. The front includes 4-piston radial calipers and a pair of 320mm floating steel discs, lightweight and able to guarantee reduced braking distances and excellent module ability. A single-piston caliper grip the 240 mm rear disc. Front and rear systems both Braided metal brake lines from the aerospace industry, which eliminate the inconveniences buffer effect of conventional lines and guarantee accuracy and resistance to force.
