SECOND GENERATION — 105 HP & WINGLETS

Mechanical and aerodynamic revision for 2025: enlarged 52 mm throttle bodies lift power to 105 hp and torque to 70 Nm, integrated aerodynamic winglets on the fairing for high-speed stability, larger bonded-glass 5" TFT for better sunlight readability, launch control and cruise control added to APRC. Standard (KYB) and Factory (full-adj Öhlins 43 mm) versions. The most accomplished RS 660 since its launch.
