The new Tuono 1100 V4 RR and Tuono 1100 V4 Factory are Aprilia’s latest naked bikes. They share the same high-performance chassis as the RSV4 superbike and have also been equipped with the latest version of Aprilia’s Performance Ride Control (APRC) suite. The key difference between the $14,599 RR and the $16,299 Factory is the use of Öhlins suspension on the latter. The new engine on the other hand, has the same layout and cases as its fully faired cousin, but its capacity has been increased to 1,077cc thanks to a new 81mm bore (up from 78). Pankl connecting rods, along with the crankshaft, are new. Thanks to the larger bore, the spread of low to mid-range torque has improved, and claimed maximum power output has increased from 170 horsepower to 175. The biggest step in horsepower comes at 8,000 rpm where Aprilia says almost 20 additional ponies have been gained.
