Motor Sport-Aprilia Tuono V4R APRC

Literasia.com-The Aprilia 2011 Tuono V4R is a bit of a shock to the system as it just pulls like an angry bull everywhere and stops as if a freight train suddenly started pulling it in reverse. This has hardly left it weedy: output is still 165bhp (167.3PS, 123.1kW) at 11,500rpm, 800rpm below the lowered rev limit and 13bhp less than the RSV4. And to keep it all in check the Tuono V4R APRC features Aprilia’s class leading traction control, launch control, wheelie control and quickshift gearchange systems.

A few key changes differentiate the Tuono engine from that of the RSV4. The ultra-compact, 78.0 x 52.3mm bore-and-stroke dimensions are identical in both versions of the 65-degree V-Four. The V4 R unit breathes through taller, fixed-length velocity stacks, optimized to fatten the lower half of the torque curve and improve throttle response below 4000 rpm. Both engines share a 13.0:1 compression ratio and breathe through 48mm throttle bodies. Claimed peak output for the Tuono is 167 horsepower at 11,500 rpm with 82 foot-pounds of peak torque 9500 rpm.

The Aprilia Tuono V4R APRC is possibly the most extreme streetfighter-type streetbike ever made. Aprilia have upped the ante by a large measure. The V4 engine with its 167 horsepower is one of the best in the business.
