Overview

Aprilia SL 900 Shiver

THE NAKED BIKE FROM NOALE GROWS IN DISPLACEMENT WITH A NEW EURO 4 TWIN- CYLINDER CAPABLE OF MORE THAN 95 HP AND 90 NM OF TORQUE NEW PERFORMANCE COMBINED WITH AN ABSOLUTELY TOP SHELF FRAME FOR A RIDEABILITY THAT RAISES THE BAR TO NEW HEIGHTS IN THE NAKED SPORT BIKE SEGMENT AN INTUITIVE, POWERFUL, AGILE AND TECHNOLOGICAL BIKE IS BORN IN THE BEST APRILIA TRADITION, DEDICATED TO ABSOLUTE RIDING PLEASUREAs always, Aprilia makes refined mechanics and an excellent chassis structure the winning values on its new bike. The new Aprilia Shiver 900 evolves the original project of a bike that, from its first appearance on the scene in 2007, marked a turning point as the first factory bike fitted with ride-by-wire technology to manage engine throttle valve electronics. A technological first from Aprilia derived directly from the racing world, the Aprilia Cube, in fact, was the first MotoGP bike to use this technology in 2002 and since then all of the global manufacturers have followed suit. The Aprilia Shiver 900 increases in performance, thanks to the new 900 V-twin engine, capable of increasing not only the power, but more importantly, the maximum torque delivered at any rpm at top levels for its category. More power and more character that translate into great riding satisfaction without sacrificing the ease and comfort that have always been characteristics of the Aprilia Shiver. It stems from a bike that has made novice and expert riders alike fall in love, thanks to its chassis architecture that, in the best Aprilia tradition, draws on the know-how of a manufacturer that has won 54 world titles in its brief history and that currently has bikes in premier competitions like MotoGP and Superbike. The new superstructures – fuel tank covers, side panels, tail fairing, front mudguard – a profound revamp to the aesthetics make the new naked sport bike from Noale stand out at a glance. The new twin cylinder also stands out for its aggressive features highlighting its distinct sport character: the wheels, frame, shock spring and the cylinder head covers are now painted red. The instrument cluster is completely new and made up of modern TFT technology to ensure information is perfectly legible. The large, 4.3” screen (the same one used on the new Aprilia RSV4 and Aprilia Tuono 1100 V4 versions) allows all on board information to be clear at all times, thanks in part to its capacity of adapting the background and font colors based on light sensor detection of conditions. Connectivity with your smartphone, provided as an accessory with the AMP (Aprilia Multimedia Platform) kit, also provides the data related to incoming/active calls on the screen, as well as information related to the use of an intercom or any audio files being played. For the first time, the easy to ride, powerful and technologically advanced Aprilia Shiver 900 now has an advanced traction control increasing safety while ensuring dedicated performance. From stop and go to flowing routes, mountain passes to touring treks, even long range the Shiver 900 invites you to fasten your helmet and set off in search of the best sensations on two wheels. A New Engine, New Power

The new Euro 4 engine grows to 900cc from the 750cc on the first version. This increase was achieved thanks to the increased stroke that means the power at the shaft exceeds the threshold of 95 HP and, more importantly, significantly increases torque at medium rpms, all to the advantage of pick up power during acceleration and coming out of corners. The 90 Nm (66.38 lb ft) of torque at 6,500 rpm that are consequently obtained guarantee pure fun in the saddle. The new powerplant maintains the 90-degree angle between the two cylinders, as well as a timing system with four valves per cylinder, dual overhead cam and liquid cooling. On the other hand, the engine now has a more efficient lubrication circuit and the new Marelli 7SM ECU. The new Shiver 900 receives the full benefits of Aprilia’s extensive experience in electronic control systems and riding support for which the Aprilia RSV4 – the supersport bike that has won seven World SBK titles (three Rider and four Manufacturer) in its racing version and that is consistently at the top of its category in the street version – is an unrivalled example. Out of this experience and from this Aprilia technological first, the Shiver 900 features an advanced traction control system that guarantees maximum safety, but also pure brilliant riding enjoyment thanks to the dual control that acts on both ignition and on the motorized throttle valves, making its intervention smooth and easy to manage. The Ride-by-wire feature, that made its début as standard equipment for a factory bike on none other than the first Shiver version, also changes and evolves. On this latest version, the system becomes lighter thanks to a reduction in weight of more than half a kilo. The exhaust pipes, one of the characterizing aesthetic elements of the Aprilia Shiver with their placement under the saddle to give the side view of the bike an extremely clean look, have also been redesigned. They maintain the original position, but the end of the silencer is shorter and directed upward. The exhaust flow is now directed downward and to the side in order to prevent interference with the passenger and to guarantee greater comfort. A Chassis Architecture Worthy of the Aprilia Tradition The performance provided by the new engine is perfectly matched to an ultra-fine chassis architecture, easy to ride and intuitive, but at the same time incredibly high performance that, in the best Aprilia tradition, is simply unmatched in the category. In fact, the mixed steel trellis/aluminum plates frame provides standard-setting stiffness, defines an extremely compact bike and ensures that it is capable of catering to all riders with no problem, as well as enhancing the riding skills of more expert motorcyclists. This makes technical routes a favorite playground for the Shiver 900. The Shiver 900 structure takes advantage of all the proverbial Aprilia know-how where frames are concerned and draws from the on-track experience gained in the Supermoto competitions where Aprilia boasts no less than seven World Titles. The trellis upper part in steel tubing is connected to wide spread aluminum lateral plates using special, high-resistance bolts. The combination formed by these elements forms an extremely stiff and lightweight frame, an extremely rational and excellent solution for reining in all the horses of the new Aprilia V90.

The contained longitudinal development of the engine has led to obtaining an agile bike, a feature that also benefits from the choice to position the shock absorber laterally. Thanks to this solution, space was created for the exhaust manifolds that have a shape and volume calibrated to perfection in order to get the best performance from the engine. This has allowed for an optimum exhaust manifold layout, without having a significant impact on the length of the bike and without thermally stressing a fundamental riding element like the shock absorber. The aluminum alloy swingarm with stiffening truss boasts stiffness values at the top of its category and it is sized to withstand the asymmetrical stress of the laterally positioned shock absorber. Aprilia Shiver 900 adopts a new 41 mm stanchions Kayaba fork, almost a half kilo lighter than the one mounted on the first version, adjustable in hydraulic rebound damping and spring preload, with chill cast feet to support the radial callipers. The 120 mm travel lets you smoothly tackle urban and mountain routes. The two steering yoke plates are made of forged aluminum. Rear shock absorber, mounted on the side, is pivoted directly to the swingarm, following the cantilever layout. Adjustable spring preload and hydraulic rebound, with rear wheel travel of 130 mm. The sporty, three-spoked rims are also new, inspired by the standard Aprilia Tuono V4 wheels and contributors to containing the weight, reducing the front by 0.9 kg and the rear by 1.3 kg. This leads to a drastic reduction of the gyroscopic effect and therefore greater agility for the bike, improved suspension functionality thanks to the reduction of unsprung masses and quicker acceleration. The new wheels come with 120/70 front tires and 180/55 on the rear. The braking system, equipped with two-channel ABS, implements radial callipers to highlight the sport-orientation and 320 mm discs on the front, and single-piston caliper with a 240 mm disc in the rear. Both front and rear systems have metal braided lines derived from the aeronautic sector, eliminating buffering effect of conventional lines while guaranteeing maximum braking precision. Original Aprilia Accessories Range: Sport and Touring A wide range of accessories dedicated to sport and touring is available for the Shiver 900 as well. The former highlight the sport soul and the unmistakable Aprilia racing character: parts in precious carbon, billet aluminum components, such as brake and clutch fluid reservoir covers, brake and clutch levers and mirrors, as well as the must-have frame guard and fork bumpers. The accessories dedicated to touring increase the comfort of the Shiver 900, such as the comfort saddle, side panniers and the seat bag. As with the other Aprilia motorcycles, the Aprilia Multimedia Platform is available which, thanks to Bluetooth connectivity and the interface with handlebar controls and the new TFT display, allow the rider to manage and share all the trip information, from data on more sport-oriented riding to touring-related information, with indications on consumption, routes and trip speeds, grip conditions and even Aprilia locations.
