Aprilia motorcycles have always been acclaimed for the excellent chassis designs. The SMV 750 Dorsoduro is no exception, thanks to a chassis that makes it the best balanced and most effective bike of its type. The new Dorsoduro is easy and intuitive to ride despite its blistering performance. It is designed to be ridden at the limit under all conditions, to perform extreme power slides, and to blast out of bends under full power. The secret lies in an ultra-responsive chassis, whose ergonomics suit riders of all statures and allow you to “take it to the limit” and enjoy the thrills of a motorcycle built for pure entertainment.
The frame incorporates all of Aprilia’s vast racing experience, and makes full use of the latest mixed steel and aluminium designs derived from the world of Supermotard World Championship racing. The top half of the frame is a tubular steel trellis. This is secured to generous aluminium side members by special high strength bolts. The resulting structure is extremely rigid and lightweight, and provides the best possible means of harnessing the exuberant power of the Aprilia V90 engine while still communicating a strong impression of lightness, high technology and Italian style.
Continuous co-operation between engine and frame designers has led to the perfection of high-tech, performance-oriented solutions and to total integration between engine and frame. The intelligent design solutions applied to Aprilia’s V twin engine have made it shorter than ever, permitting the development of a rational and efficient frame and a superbly agile and incredibly responsive motorcycle.
The lateral position and acute angle of the rear monoshock has freed up the space needed to ensure optimum exhaust geometry without any increase in the bike’s overall length, and without subjecting the monoshock to thermal stress. The aluminium swingarm is robust enough to withstand the asymmetric stresses generated by the lateral positioning of the rear suspension. The swingarm has been specially developed to satisfy the needs of a supermotard like the SMV 750 Dorsoduro, and combines excellent torsional rigidity with the elasticity needed for precision under acceleration and intuitive control under changing conditions.
SUSPENSION: EFFECTIVE ON ALL SURFACES
Optimum suspension setup has always been one of the strong points of the Aprilia design and testing team. The 43 mm upside down fork features shell-cast bottom outers with radial calipers mountings, and offers adjustments for spring preload and rebound damping. This sophisticated fork offers a superb sliding action and a wheel travel of 160 mm in line with the latest trends in supermotard racing. Both yokes are forged, and the top yoke is also anodised to match the Dorsoduro’s high level of finish.
The laterally offset monoshock pivots directly on the swingarm in a cantilever configuration, and is also adjustable in spring preload and rebound damping. Rear wheel travel is 160 mm, again in keeping the requirements of a top level supermotard, on which effective, controlled long stroke suspension is a must.
BRAKES: RACING TECHNOLOGY
The Aprilia SMV 750 Dorsoduro is equipped with the best braking technology currently available. The front brakes feature 4-piston radial calipers, state-of-the-art for the motard market. The lightweight, 320 mm wave discs ensure shorter than ever stopping distances. The bike’s aggressive stopping power is emphasised by the mean look of the braking system, in keeping with the Dorsoduro’s overall styling.
The rear brakes incorporate another wave disc, 240 mm in diameter this time, plus a single piston caliper. Both the front and rear brakes are fitted with aeronautical type metal braided brake lines to eliminate the sponginess associated with conventional rubber hoses and to deliver maximum braking precision.
COMPONENTS
Supermotards are always no-frills machines, and sometimes quite spartan. This, however, does not mean having to do without top quality components and attention to detail. Here too Aprilia stands apart from the competition by adopting a level of equipment worthy of a true market leader:
Matrix instrumentation. The mixed analog/digital instrument cluster receives data over a CAN line and incorporates a memory that forms an integral part of the diagnostics system. The ultra-compact instruments feature a modern design and are extremely light in weight. All functions can be accessed and controlled from the handlebars.
The LED backlighting is white in the analog area and red in the digital area, and can be adjusted to three levels of brightness.
Dual taper anodised aluminium handlebars exactly like those fitted to Aprilia’s racing supermotards. This super-lightweight component is specially designed for optimum dynamic control.
Hydraulically operated clutch for a consistently precise action and exceptional smoothness. The clutch is also self-adjusting and completely maintenance free.
