Description

2026 Aprilia® RS 660

BORN TO LEAD

The RS 660 is a masterpiece of technology and advanced electronics. Its active electronic controls and racing-derived aerodynamics complete with winglets provide plenty of thrills on road and track alike while the sporty 105-hp twin-cylinder engine and contained weight make it capable of performance that is simply unrivalled in the category and set a new standard of sportiness. Breathtaking to behold, it is the perfect embodiment of Aprilia’s essence in terms of innovation, sportiness and Italian design.

Features may include:

DESIGN
  • Sculpted by the wind

With a design that exudes power in every detail the Aprilia RS 660 makes no compromises. Its compact, sculpted lines define the aerodynamic dual fairing, featuring a large front wing paired with two additional winglets to optimise airflow and enhance high-speed stability.

The aggressive character of the front end is further emphasised by full-LED lighting with a distinctive signature. Meanwhile, bold graphics and striking colour contrasts reinforce its Aprilia's sporty nature and rich racing heritage.

BALANCE
  • Because speed equals rhythm

The RS 660 is designed to deliver extraordinary performance. The APRC package, which includes a quickshifter and Launch Control as standard, ensures lightning-fast starts and gear changes. Six-axis IMU, which live monitors the bike’s parameters in relation to the road conditions combines with Ride-by-Wire throttle to provide optimal control. The RS 660 is also a star when it comes to braking with multimap Cornering ABS making for impeccable stopping even when the bike is leaning. And while you experience the adrenaline of the ride, the backlit controls and the 5” colour display with optical bonding offer maximum visibility and seamless interaction, allowing you to focus entirely on the road.
