Positioned in Aprilia's sport motorcycle lineup, the 2026 Aprilia RS660 Factory relies on a 659 cc engine powerplant. In factory specification, peak output is rated at 105 HP while maximum torque reaches 70 Nm. With a specific output of 159.3 HP per liter, the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.

Rider ergonomics and chassis geometry center around a 820 mm (32.3 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams.
