UPDATE: Larger photos and more details have been added.

Well here’s your first look at the 2011 Aprilia Tuono V4 R. While we don’t have official information, the Tuono V4 line seemingly comes equipped with the Aprilia Performance Rider Control package. Sharing its frame with the RSV4 superbike, the Aprilia Tuono V4 R receives a de-tuned motor with performance figures coming in at 162hp and 81 lbs•ft of torque. Like the Aprilia RSV4 Factory APRC SE, the Tuono V4 R will be fitted with APRC system, which will bring traction control, anti-lock brakes, wheelie control, launch control, quick-shifter, and rider-selectable driving modes to the naked V4.

Braking power comes from radial Brembo monobloc calipers mated to 320mm discs up front. Suspension is done by Sachs, with 43mm titanium nitride (TiN) forks and a four-way adjustable (compression, rebound, pre-load, and ride height) rear shock with piggyback reservoir. The 2011 Tuono V4 R comes with new wheels that are 5 lbs lighter than the ones that come on the Aprilia RSV4 R. We apologize for the small photos after the jump, but perhaps that’s better so as to help you avert your eyes from this abortion of a motorcycle.

Derived from the flagship 2011 Aprilia RSV4 APRC, Aprilia set out to make the most powerful street naked on the market, and have clearly met that goal, besting the rival Ducati Streetfighter by 7hp. Aprilia says the 2011 Aprilia Tuono V4 R will tips the scales at 394.6 lbs with fuel, making the Tuono V4 R a very light package. Helping it reach that weight is its lighter wheels and exhaust (both of which shave 5 lbs off the bike’s curb weight). Seat height is 33″ while the fuel tank holds 4.5 gallons. No word yet on pricing or availability, but expect it to be aggressively priced against the Ducati Streetfighter, we’d expect in the $14,000 range.
