2011 Aprilia Tuono V4R – Click above for high-res image gallery

It takes a lot to make a term like "naked" any sexier, but Aprilia has managed to do exactly that with its latest "naked bike," the new Tuono V4R. A beast of a machine (that looks sort of like an insect), the Tuono is based on the RSV4, but ditches the bodywork for a two-kilogram weight savings and a better view of the 1000cc DOHC V4 engine, which produces 162 horsepower and 81 pound-feet of tire-smoking torque. But the Tuono isn't just about grunt. In fact, it's one of the most sophisticated naked bikes on the market, and it's coming to the United States towards the end of next year.

Keeping all the twist and shout in check are the Aprilia Performance Ride Control and advanced traction control systems. The PRC is a three-position wheelie control system with programmable launch control that employs more accelerometers and gyroscopes than an Apple Store, allowing a little wheelspin out of the corners and offering eight modes that are adjustable right from the handlebars. The traction control, meanwhile, can automatically optimize itself according to the tires you've fitted. Yeah, that's pretty sophisticated. Pretty sexy, too, and you can check it out in closer detail in the high-resolution image gallery below.

The heart racing, soul stirring naked.

After creating the best superbike of the new millennium, Aprilia revolutionizes the supersports naked segment with its astonishing new Tuono V4R.

A bike that goes beyond the wildest dreams of even the most hardcore enthusiasts - the rider who, given the chance, would use a race bike just to go for a coffee.

For riders like these and for those with power in their veins, Aprilia has created a motorcycle with the indomitable spirit of the RSV4 in a feline body that is in its element when accelerating and braking with unimaginable violence, that eats up curves of any radius and swallows straights whole.

Characterized by the brazen exhibition of the V4 65° engine framed by the brushed aluminum elements of the dual beam frame, the Tuono V4 is a naked dressed with the bare necessities to mount up and instruct according to the rider's capabilities.

Adding yet another touch of aggressiveness is the aerodynamic new top fairing tipped with two polyelliptical headlights at the sharp end, which gives the bike the unequivocally mean, daunting stare that you'd expect from a machine with an incredible 162 horsepower.

Tuono V4R boasts power never before installed on a naked, obtained by reconfiguring the RSV4 Factory APRC SE four V cylinder.

The Tuono V4R inherits features from the Special Edition including the new exhaust system with bypass valve, which is two kilos lighter than the system used on the RSV4 R, and latest generation Ride by Wire throttle control.

Differences from its race track sibling are closer spacing between the three first gear ratios a maximum torque of 79.4 lbs-.ft. (110 Nm) on tap 1000 rpm lower.

The Tuono V4R maintains the family feeling with the WSBK double title champion's tail fairing, saddle, tank and side panels, one of the best examples of made in Italy motorcycle design in the last decade for its formal beauty and functionality ratio. The racer, because that is what anyone who approaches a fireball like this one should be called, will be taming this beast from a riding position tailored to create a symbiotic relationship between the body and the bike, for unparalleled feedback through the three points of contact - the saddle, footpegs and handlebars.

Staying in the saddle and gripping the biconical handlebar, the rider comes into contact with the APRC (Aprilia Performance Ride Control) joystick, the second generation electronic dynamics control package developed by Aprilia to get as close as possible to the physical limits of riding: State-of-the-art in bike dynamics performance controls, a patented system which makes the winning Superbike technology available to any biking enthusiast. All of this with absolutely simple and intuitive management which allows the Tuono V4R to be customized every time the rider gets on it, making it a truly "tailored" bike for each rider, the desired performance and the riding conditions.

APRC is based on an automotive inertia sensor platform, with two gyrometers and two accelerometers allowing the ECU to determine the dynamic state of the motorcycle and control engine torque accordingly to help the rider exploit the full performance potential of the bike in all conditions.

The APRC package includes ATC traction control (Aprilia Traction Control), with eight selectable levels, which controls sliding when accelerating out of a curve in relation to bank angle and throttle aperture, AWC (Aprilia Wheelie Control), which helps the rider control extreme wheelying by gradually bringing the front wheel back to the ground, and 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 arms the system, as confirmed by the specific message on the display. From this moment on, all 162 horsepower of the beast from Noale are ready to slingshot the Tuono V4R like a missile as soon as the rider releases the clutch, unleashing the astonishing power onto the tarmac through every available square millimeter of the 190/50 rear tyre.

For every day street riding and for those who are not yet accustomed to the miracles of the vehicle's dynamics software, Tuono V4R offers great satisfaction from a biking hardware point of view.

In fact, the extraordinary new Aprilia naked is equipped with the best components available on the market: Brembo brake system with radial calipers and 320 mm floating discs at the front (220 mm at the rear), aluminum wheels with an all-new design weighing 2 Kg less than those on the RSV4R, Sachs upside down front fork with 43 mm stanchions coated with titanium nitride for reduced friction, 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 or for two-up use.

NEW YORK (November 2, 2010) – Piaggio Group Americas (PGA), the North American importer and distributor of Italy's Aprilia, Moto Guzzi, Piaggio and Vespa brands, today announces nine exciting new models that will ship to certified dealers over the course of 2011. Revealed today at EICMA 2010 in Milan, PGA will offer motor enthusiasts additional entries in the motorcycle, scooter and urban mobility sectors. As is customary, models revealed at EICMA traditionally materialize in the U.S. six to twelve months later. As models ship, new model information will be available on the brand-specific website.


For riders with a need for speed and agility, Aprilia offers four new models to its intense lineup of powerful motorcycles. Derived from the bike that won the coveted 2010 World Superbike Championship Triple Crown - Manufacturer's Title, Team Title and Rider Title with race pilot Max Biaggi – the RSV4 – Aprilia unleashes the RSV4 Factory Special Edition (SE) with the exclusive Aprilia Performance Ride Control package (APRC), which offers superbike race technology to professional and recreational riders alike. Aprilia also applied its knowledge gained on the track to the Dorsoduro 1200, an explosively powerful and extremely agile, twin-cylinder motard, offering riders a balance of performance, precision and excitement. Both the RSV4 Factory SE APRC and Dorsoduro 1200 will be in dealerships in the spring of 2011. Aprilia also designed a bike that novice riders could enjoy -- the RS4 125. It is the successor and most advanced evolution to date of the RS 125, the bike that dominated the 125cc sports class for years and remains the most highly sought after machine among riders competing in the Sport Production Category. The Aprilia RS4 125 introduces the highly advanced, all-new 4 stroke powerplant to the sports segment, while adopting styling and technical solutions inherited from the RSV4. The much anticipated Tuono V4R was also shown at EICMA and, along with the RS4 125, is planned for arrival in the U.S. at the end of 2011.
