The 2011 Aprilia Shiver 750 Street Motorcycle

Aprilia 2011 Shiver 750

It is certainly no easy matter to take the lead in a class as fiercely competitive as the medium powered naked class.

A class where the battle is not just about technology and performance, but also design, component rationality and riding ease and pleasure, elements which are not always compatible and are particularly demanding for designers and engineers.

Aprilia has picked up this challenge and interpreted it by applying its own successful philosophy to a completely new design, destined to set new standards for years to come.

A bike both strongly aggressive and at the same time clean-cut and elegant, in perfect Aprilia style.  A bike at the top of its class for its sporty personality, designed on the basis of the know-how of a company which has to date won 250 world championship victories.

The Aprilia Shiver 750 is the naked everyone was waiting for. A design able to satisfy the disparate needs of those buying this type of bike.

From everyday use to a trip along mountain passes or use on the racetrack, the Aprilia Shiver 750 is completely at home in any situation, guaranteeing pure riding pleasure at all times.

THE DESIGN: SHAPE AT THE SERVICE OF POWER

As with every Aprilia product, the Shiver 750 has a highly innovative design where form and function come together to create an almost perfect object. The Aprilia Shiver 750 is pure technology and this is evident in its sharp, sporty lines.

The frame and engine, both brand new, are the foundations of the design and are also, rightly, the main elements characterising the look of the Shiver 750. Each element has been designed to be not just beautiful but also functional. The design is refined, but at the same time clean-cut, without too many frills for the maximum possible functionality. The Aprilia Shiver 750 exhaust is also a very distinctive design element. On the Aprilia Shiver 750, the technical component becomes a design element at the same time, creating a bike both aggressive and at the same time elegant.

The tank-seat-tail assembly further emphasises the compactness of the bike. The rider becomes one with the machine, perfectly integrated in the short, agile, and sporty bike. This helps establish an immediate feeling between the rider and the bike, making everyone feel as if they have always been riding it. The strongly tapering tail also incorporates the twin exhaust with triangular silencers, a feature which makes the design even more aggressive, while keeping weight distribution highly symmetrical.

The Aprilia Shiver 750 is compact, functional and attractive. The adoption of a side shock absorber not only adds a further distinctive feature to the look of the bike, but also enables a rational and compact exhaust system to be fitted.

This Motorcycle comes with a 90° V2 engine with four valves per cylinder, and a double overhead camshaft with liquid cooling

THE V90 ENGINE: TECHNOLOGY IN THE PURE STATE

The V90 engine inherits all Aprilia’s experience in high performance mechanics. Endless hours of bench and road tests have produced a genuine masterpiece of mechanical engineering, capable not just of high performance, but also complete reliability. Thanks to its particular technical characteristics, the Aprilia V90 combines high specific power with maximum usability and easy riding.

A generous twin cylinder heart, destined to set new performance and technology standards for medium powered bikes. The engine has been designed by the Aprilia Research and Development department which set out to create a powerful and reliable engine requiring very limited maintenance.

THE FRAME: RATIONALITY AND EFFICIENCY

Experts have always acknowledged that Aprilia bikes have the best chassis in their class. The Aprilia Shiver 750 is concrete confirmation that once again Aprilia has managed to create a chassis which is both extremely easy and intuitive and incredibly high performance. The frame exploits all the knowledge Aprilia has gained in racing and also draws on new studies on mixed structures with the futuristic RXV and SXV, already winners of a number of titles on the racetrack. The top part of the tubular steel trellis is connected to large side plates by means of special high strength bolts. This creates an extremely rigid lightweight frame, the best solution to harness all the horsepower of the Aprilia V90.

Creation of an Aprilia bike always involves synergy between chassis and engine engineers. The fundamental design choices for the V90 engine led to construction of a highly rational and efficient frame. The reduced longitudinal dimensions of the engine made it possible to obtain a short, agile bike, helped by the particular side positioning of the shock absorber, not a simple cosmetic mannerism, but a precise technical decision which created valuable space for the exhaust manifolds whose shape and size have been calibrated perfectly to ensure maximum engine efficiency. This enabled the optimum exhaust manifold configuration to be obtained, without too heavily affecting the length of the bike and without exposing the shock absorber, a fundamental element for the ride, to heat stress.

The aluminium swingarm with reinforcement truss has been sized specifically to support the asymmetrical stresses caused by lateral positioning of the shock absorber. The rigidity of the swingarm sets new standards for the class.
