Aprilia bikes have always been considered as the benchmark for chassis excellence. And true to tradition, Dorsoduro 750 is one of the most effective, best balanced bikes in its class. The new Dorsoduro is easy and intuitive to ride, yet still delivers mind-bending performance. This machine is designed to be ridden at the limit in any conditions, allowing the rider to turn on a dime and blast out of bends with the throttle wide open. This is made possible by the incredibly responsive chassis architecture, which has been designed with particular focus on ergonomics, allowing the Dorsoduro 750 to adapt perfectly to any rider and letting all users access the extreme potential of this pure fun machine in any situation.
The chassis exploits the most of the notable expertise acquired by Aprilia during competitions, fully drawing on the experience gained on the mixed structures used in the Supermoto world championship. The upper narrow tubular steel trellis section is connected to the generously sized lateral aluminium plates by special high strength bolts. The result is anextremely stiff, light structure and the best solution possible for reigning in the exuberant power of the Aprilia V90, with looks that conveys lightness, ultra-advanced technology and Italian style.
Ongoing collaboration between the powertrain engineers and the chassis engineers has produced optimised solutions in terms of technical content and performance, and resulted in mechanicals that are integrated perfectly into the frame. The architecture chosen for the Aprilia twin, which is optimised for longitudinal compactness, made it possible to create a rational, effective frame and, as a result, a bike that is incredibly agile and reactive.
The lateral and substantially raked position of the shock absorber freed up lots of precious space for an optimised exhaust manifold geometry without influencing the length of the bike or exposing the shock absorber itself to thermal stress. The aluminium swingarm is sized to support the asymmetric stress caused by the lateral positioning of the shock absorber. This component has been specifically conceived for the needs of a super-motard like the Dorsoduro 750 and responds ideally to requisites for torsional stiffness and elasticity, which are indispensable for precise wheel placement and to ensure communicative feedback in transitory conditions.
Defining the optimum suspension configuration has always been a point of pride for Aprilia's engineers and test team. The 43 mm upside down fork, with shell-cast brackets supporting radial callipers,features adjustable spring preload and hydraulic rebound damping. This is a highly sophisticated unit offering class-leading progressiveness and generous wheel travel (160 mm), in keeping with the philosophy of the motard genre.Both steering yokes are forged elements, while the upper yoke is also anodised, confirming the outstanding level of finish on the Dorsoduro.
The lateral shock absorber is pivoted directly onto the swingarm in a cantilever layout, and features adjustable spring preload and hydraulic rebound damping; rear wheel travel is 160mm - this is also in keeping with the philosophy of the motard, which demands suspension that is effective and controlled, but also offers ample wheel travel.
The Aprilia Dorsoduro 750 boasts the best braking technology available today. The front brake system, with 4-piston radial callipers, is the most advanced of its kind in its segment. The lightweight 320 mm floating wave discs ensure shorter stopping times, while their extreme looks, which are in perfect keeping with the overall style of the Dorsoduro, visually express the aggressive power of the braking system.
The 240mm rear disc is also of the “Wave” type and is braked via a single piston calliper. Both the front and rear systems have metal braided braking pipes, derived from the aeronautic sector, which eliminate the undesirable pressure fluctuations of conventional pipes and guarantee maximum braking accuracy.
On the Dorsoduro 750, safety is further enhanced by a sophisticated 2-channel Continental ABS system. This ABS system is specifically calibrated to let the rider fully exploit the power of the brakes and the grip of the tyres in the dry, so as not to detract from the immense fun of this bike.
