Hot on the heels of the release of Aprilia?s fully-faired RS 660, the Italian marque has unveiled the 2021 Aprilia Tuono 660, its new middleweight addition to the Tuono family of motorcycles. The Aprilia Tuono 660 utilizes the same stellar 659cc parallel-twin engine, sporty chassis, and top-shelf electronics package from the RS 660 but delivered in an upright naked sportbike. Stripping the 660 naked has also lowered the price $800 to an attractive $10,499.

Powering the 2021 Aprilia Tuono 660 is a punchy 659cc parallel-twin engine, based on the architecture of Aprilia?s legendary V4 powerplants, producing a claimed 95 horsepower. Based on our review of the 2021 Aprilia RS 660, we can expect that the Tuono 660 will deliver ample low and midrange power that?s perfectly suited for street riding. The engine is equipped with a slick 6-speed gearbox, as well as an up/down quickshifter. One notable change for the Tuono 660 is that the final drive gearing has been shortened, improving acceleration and allowing riders to capitalize on the engine?s healthy torque.
Aprilia hopes that the Tuono 660 will attract new riders and those moving up from lightweight motorcycles. Notably, the middleweight RS and Tuono 660 serve as crucial steppingstones in the Aprilia lineup, allowing riders to develop their skills before saddling up on the monstrously powerful RSV4 and Tuono V4 motorcycles.
