Best in Class
Powered by a new twin-cylinder engine, the naked bike from Noale grows in engine capacity to guarantee more torque and more fun. 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 maximum riding pleasure.
As always, Aprilia makes refined mechanics and an excellent chassis structure the winning values on its new bike. Aprilia Shiver 900 evolves the original project of a motorcycle 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.
This new 2019 updated model includes a built-in navigation system housed within the speedo units.
The Design: A Non-Conventional Sport Naked
A non-conformist naked, the new Aprilia Shiver 900 places even more emphasis on a distinctive design: from the lateral air intake ducts that embrace the front end to the characteristic compact rear end with the exhaust pipes positioned under the saddle, the new superstructure – fuel tank side covers, side panels, tail, front mudguard – the aesthetics have been deeply revamped.
The new twin cylinder also stands out for its aggressive features that highlight its distinctly sporty character: the frame, the shock absorber spring and the cylinder head covers are now painted red. Adrenaline-charged details that blend with the three available colour schemes – Black, Red & Silver – creating an original contrast.
Another characterizing element of Aprilia Shiver, the exhaust, has been redesigned: while maintaining the position under the saddle that contributes to an extremely clean side view of the bike, the terminal part of the silencer is now shorter and aimed upward. A brand new exhaust bottom made up of concentric rings ends in a concave disc: a further bold stylistic element that makes the Shiver immediately recognizable even from the rear, as well as being a practical way to send the exhaust fumes downward, thereby avoiding interference with the passenger and ensuring greater comfort.
Engine: We Write Torque, You Read Fun
The new Euro 4 engine grows to 900 cc from the 750 cc on the first version. This increase was achieved thanks to the increased stroke that clearly increases torque in the mid-range, all to the advantage of a better response during acceleration and exiting corners. The 90 Nm of torque at 6,500 rpm that are consequently obtained guarantee pure fun in the saddle. This is was one of the main objectives for the Aprilia engineers in designing the new twin-cylinder. The power, which increased in any case to over 95 HP, stems from the decision to comply with the legal limits in order to be able to obtain approval for the version with power limited to 35 kW as well, that can be ridden with an A2 class driver’s license. Aprilia Shiver 900 is therefore an easy bike to ride even for new bikers, accompanying them in their personal evolution of experience in the saddle.
The new powerplant, that maintains the 90 degree angle between the two cylinders as well as the four-valve timing per cylinder, dual overhead cam and liquid cooling, was the subject of various changes, including an important operation aimed at reducing friction on the pistons, completely redesigned and now characterized by a special anti-friction feature on the mantle, whereas new pins new pins have led to a lightening of the alternated parts in motion. The crankshaft also changes, with revamped balancing.
On the other hand, a new and more efficient semi-dry carter internal lubrication circuit helps to reduce losses of power due to shaking and to keep consumption and temperature of the lubricant to a limit, thereby eliminating the need for an oil radiator. Improved efficiency was also achieved on the combustion front thanks to the introduction of new injectors: the increase of fuel pressure allows better fuel/air mixture spray with benefits for consumption and emissions. Contributing to bringing the engine to within the limits established by the Euro 4 pollution standard is also the exhaust system, fitted with a double oxygen sensor. The Aprilia Shiver 900 engine is also fitted with an automatic decompresser which makes it easier to start in low temperature conditions.
The unit fitted on the Aprilia Shiver 900 also gains the Marelli 7SM ECU: a substantial evolution that, on one hand, has allowed a refined traction control system to be introduced and that, on the other hand, has led to a significant simplification of the electrical system; in fact, the engine control and management systems, functions that were previously carried out by two separate electronic control units, are now integrated in a single hardware components, the same one fitted on the V4 models from Noale.
All of the clutch components have been redesigned: The load on the clutch lever has decreased by 15%, whereas the primary drive reduction ratio has been changed to optimize exploitation of the available power.
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 unrivalled in the category. In fact, the mixed steel trellis/aluminium plates frame provides standard-setting stiffness, defines an extremely compact bike and ensures that it is capable of catering to fledgling riders with no problem, as well as enhancing the riding skills of more expert and discerning bikers. This makes flowing routes a favourite playground for the Shiver 900.
The structure of Shiver 900 draws from all the proverbial Aprilia chassis architecture know-how, as well as their experience on tracks all over the world. The trellis upper part in steel tubing is connected to wide spread aluminium lateral plates using special, high-resistance bolts. The combination formed by these elements forms an extremely stiff and lightweight frame, an 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 aluminium alloy swingarm with stiffening truss boasts stiffness values at the top of its category and it is sized to withstand the asymmetrical stress due to the lateral positioning of the shock absorber.
Aprilia Shiver 900 adopts a new Kayaba fork, with hydraulics adjustable in extension and spring preload, almost a half kilo lighter than the one mounted on the first version, with 41 mm stanchions with chill cast feet to support the radial callipers. The 130 mm travel lets you smoothly tackle urban and mountain routes. The two steering yoke plates are made of forged aluminium.
The rear shock absorber, mounted on the side, is pivoted directly to the swingarm, following the cantilever layout and it is adjustable in spring preload and hydraulic rebound. Rear wheel travel is 130 mm.
The sporty, three-spoked wheel 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 wheel rims are shod with 120/70 tyres on the front and 180/55 on the rear.
The braking system, equipped with two-channel ABS, implements radial callipers to highlight the sportiness of the project and 320 mm discs on the front. On the rear, a 240 mm disc is gripped by a single-piston calliper.
Both the front and rear systems have metal braided brake lines derived from the aeronautic sector, which eliminate the annoying buffering effect of conventional lines and guarantee maximum braking precision.
