2026 Aprilia RS 660

The RS 660 is built for riders seeking strong cornering performance without the demands of a liter-class superbike. The 659 cc twin delivers strong midrange power and smooth high-rev performance. The chassis feels light, precise, and stable, with well-controlled braking.

Direct competitors include Yamaha R7, Triumph Daytona 660, and Aprilia Tuono 660. The Yamaha is more aggressive but less practical, the Triumph more mature, and the Tuono more upright and everyday-oriented.

Within the Aprilia lineup, the RS 660 sits above the RS 457 and below the V4 superbikes.
