2011 Tuono V4 R
When the Aprilia V4 broke cover a few years ago I immediately began to wonder how long it was going to be before Aprilia would offer it as a naked bike. That has been answered. The new 2011 Aprilia Tuono V4 R motorcycle has broken cover.
Based on the all-conquering Aprilia that took home the 2010 World SBK crown, the new Tuono V4 R transforms the revolutionary Superbike into a more accessible street sport package without losing one iota of its motorcycle racing soul.
For starters the new Tuono is saddled with the same mighty V4 that powered Max Biaggi to numerous top speed records at circuits all over the world on his way to the Superbike title.
The Tuono utilizes a reconfigured RSV4 Factory APRC (Aprilia Performance Ride Control) SE V4, with the 65-degree engine delivering 162 horsepower through a second generation of electronic engine management engineered to provide the highest level of performance while ensuring a controlled ride.
The APRC system uses two gyros and two accelerometers to determine the state of the motorcycle (lean angle, degree of throttle, etc.) and modulating power delivery accordingly. The system includes ATC (Aprilia traction control), offering eight selectable levels, all working to control sliding when accelerating out of a turn, greatly reducing the chances of a highside.
Aprilia also equips their Tuono V4 R with AWC (Aprilia Wheelie Control), designed to gradually lower the front end when a motorcycle rider gets over-zealous with the throttle, preventing looping.
Another patented technology under the Aprilia name; AQS (Aprilia Quick Shift), allows full throttle, clutchless upshifts. And last, but not least, ALC (Aprilia Launch Control), which prevents looping your precious Tuono from a standing start. All very cool WSBK racing stuff.
All of this superbike racing technology has been tamed somewhat for the street with a reconfigured transmission that has a slightly closer spacing between first, second and third gear, while delivering maximum torque at a full 1000 rpm lower than the RSV4 to make the Tuono a more user friendly motorcycle.
Rounding out the power system the Tuono V4 R has a motorcycle exhaust system that is two kilos lighter than that of the RSV4 R. All of this brute power is delivered through Ride-by-Wire throttle control.
The Aprilia Tuono V4 R, stripped of its bodywork, makes the signature brushed aluminum dual beam chassis more prominent. What little bodywork remains is an aerodynamic bikini fairing fitted with two polyelliptical headlights that stare down the competition with a mean attitude.
As a naked upright with semi-wide handlebars, the V4 R motorcycle offers unparalleled maneuverability. Seating position, peg location and reach to the bars is designed as much for performance as it is comfort.
As can be expected from Aprilia, the Tuono V4 R APRC possesses nothing but the finest of components; Bembo brake units, new lightweight aluminum wheels, Sachs 43mm inverted forks and Sachs rear shock, all accentuating Aprilia’s attention to detail on every square inch of their motorcycle.
A World Superbike Champion in the buff. How Italian.
