APRILIA TUONO V4 R APRC

The V4 Tuono is the only naked bike with a V4 engine. With 167.3 hp it is also the most powerful, and, with a completely revised chassis architecture, it sets a new benchmarks for the class.

This is a naked sports bike capable of dominating any road with its indomitable performance and with the most advanced active safety features in its class.

It has triple mapping for instantly tailoring the performance to your own preferences.

It is also available with APRC - the second generation dynamic control suite consisting of Traction Control, Wheelie Control, Quickshift and Launch Control.

After creating the best superbike of the new millennium, Aprilia revolutionises the supersports naked segment with this astonishing new Tuono V4 R. A bike that goes beyond the wildest dreams of even the most hardcore enthusiasts.

For riders with powerlust in their veins, Aprilia has created a motorcycle with the grunt of the RSV4 and the styling and comfort of a road bike with the ability to tackle mountain passes or open roads with the best of them.

The 65° V4 engine has the most advanced electronics available in a motorcycle today.

Like the original Tuono, the new V4 R is also immediately recognisable with its triple headlight fixed top fairing, the distinguishing trait of a bike which, like its twin cylinder predecessor, has the engine and chassis of its WSBK homologated sibling, but now - as well as having two world championships (the 2010 constructors' and riders' titles) under its belt - features two more cylinders and 41 horsepower more than before, while weighing over ten kilos less.

Adding yet another touch of aggressiveness is the aerodynamic new top fairing tipped with two polyelliptical headlights and LED indicators at the sharp end, which gives the bike a mean, daunting stance that you'd expect from a machine with this power.

Let's look at the engine performance first:

ENGINE PERFORMANCE

Tuono V4 R boasts more power than ever seen before in a naked bike. Like Biaggi’s RSV4 it uses a narrow V (65°) 4 cylinder engine with unique characteristics. Extremely compact, as slim as a twin-cylinder and installed in an ultra-compact chassis, the 65° V4 engine is the epitome of Italian engineering ingenuity. The Tuono gives away very little to its RSV4 sibling in terms of pure performance, but in exchange offers a greater drive in the midrange that makes it more enjoyable and rewarding to ride on the road and when carrying a passenger.

To achieve this, the Aprilia engineers looked at 3 areas: exhaust, the gearbox and the engine itself.

Exhaust

First is the new exhaust system with bypass valve which is two kilos lighter than the system used on the RSV4 R, The mapping has been altered to suit with the latest generation Ride by Wire throttle control with three rider-selectable maps (Track, Sport and Road).

Gearbox

Next up is the gearbox. The first three gear ratios are now shorter, which, with the revised power curve make the Tuono V4 R more responsive at low and mid engine speeds while retaining the characteristic top end power of a 4 cylinder engine.

Engine

The engine has been reconfigured to make it better suited to street use. It now makes 167.3 hp at 11,500 rpm, 111.5 Nm at 9,500 rpm and the rev limiter is set to 12,300 rpm in all gears

To achieve these results, a number of different modifications were made to the RS V4 engine:
  • New revised valve timing
  • Fixed intake ducts now 20 mm longer
  • Crankshaft flywheel with increased inertia for improved smoothness and overall balance
Electronic management system

The electronic management system is another example of the 65° V4 engine's technological supremacy. Full Ride by Wire technology eliminates any direct connection between the throttle grip and the throttle valves, which are entirely controlled by a latest generation Marelli control unit that also controls the ignition and the 4 injectors.

Each cylinder bank has a dedicated servo unit actuating its own two throttle bodies only. This means that the aperture of the throttle valves and, as a consequence, the quantity of fuel injected, can be controlled independently. This solution opens up practically infinite possibilities for power delivery control and works hand in hand with the APRC system.

This technology, aimed specifically at the prevalently road based usage of the Tuono V4, offers immediately tangible benefits to the rider, with triple mapping (adjusting power delivery and maximum power) selectable directly from the handlebar allowing the character of the bike to be modified to suit the rider's personal riding style or the track conditions at any time.
  • T - TRACK: no compromise. All 167.3 hp of power available at the slightest twist of the throttle
  • S - SPORT: maximum fun on the open road. Smooth delivery, maximum power. Torque limited in all gears for fun yet less demanding riding.
  • R - ROAD: usability in all conditions. Smooth delivery and power reduced by 25% across the rev range. Greater usability in all conditions. Ideal for the city or wet road conditions.
THE APRC EQUIPPED TUONO V4 R INCLUDES
  • ATC (Aprilia Traction Control) with eight different settings for controlling sliding when powering out of curves in relation to bank angle and throttle opening. The system has been tweaked to make the more conservative settings even more suitable for road use, while leaving the racing potential of the less restrictive levels intact
  • AWC (Aprilia Wheelie Control) which helps the rider maintain control in extreme wheelie conditions by gradually bringing the front wheel back to the ground, has been appropriately adapted for the different weight distribution of the Tuono V4
  • AQS (Aprilia Quick Shift) which allows instantaneous upshifts without closing the throttle or using the clutch
Completing the suite of four functions is the most exhilarating of all:

ALC (Aprilia Launch Control)

Simultaneously pressing both buttons on the joystick on the left hand handlebar activates the system, as confirmed by the specific message on the display.

From this moment on, full power (all 167,3 horsepower of the beast) is available to slingshot the Tuono V4 R like a missile as soon as the rider releases the clutch, delivering as much power onto the tarmac that the 190/55 rear tyre can handle. And tyre size does not matter to APRC, as with its Calibrating function, it is the only system of its kind on the market capable of self-adapting to tyre size and drive ratio.

THE TUONO V4 R

Unlike the previous generation twin cylinder Tuono 1000R, the frame developed for the Tuono V4 R has been completely revised with respect to the unit used in the RSV4 to maximise directional control and stability for a naked capable of over 270 Km/h (on the track, of course) while maintaining the legendary safety and impeccable precision typical of Aprilia frames.

First of all, the engine sits lower in the frame to counteract the higher, more upright riding position. Rake and trail have been appropriately adjusted to suit.

The Aprilia Tuono V4 R comes equipped with the best components available on the market:
  • Brembo brake system with radial callipers and 320 mm floating discs at the front (220 mm at the rear)
  • Aluminium wheels with an all-new three spoke design weighing 2 kg less than the five spoke version
  • Fully adjustable Sachs upside down front fork with 43 mm stanchions, and Sachs shock absorber with separate piggy back nitrogen canister featuring adjustable spring preload, compression and rebound damping and length, to modify the setup of the bike to suit different riding styles, roads and loads - including a passenger.
The choice of dual-compound tyres is also new, with three different sizes approved for the rear wheel: the 190/55 tyre fitted as standard may be replaced with a 200/55 or a 190/50 tyre to explore the full performance potential of the bike - even on the track.

The new bike is available in two different configurations:
  • Tuono V4 R (will not be imported into this Country)
  • Tuono V4 R APRC - in a choice of three colours: competition black, sunlit yellow and wing grey. The Importers have ordered the yellow and grey but they have been informed that these will only become available to South Africa next year, should International demand allow it.
Tuono V4 R APRC is a bike with two personalities, with two distinct display modes - Road and Race - to cater for even the most Jekyll and Hyde of riders.
