Aprilia RS 660 by Piaggio - middleweight sportbike with Euro 5 twin

Aprilia RS 660 delivers 100 hp from a 659 cc parallel-twin and brings superbike design into the mid-segment. This product is driving the price of Piaggio & C. SpA stock (ISIN DE000PIAG239).

Aprilia RS 660 leans on its side stand, red fairing catching the afternoon light while the matte-black tank feels cool under your palm after a short test ride. The parallel-twin hum still rings in the ears of test rider Luca Rossi as he pulls off his gloves.

Engine, performance, and riding feel

Under the fairing, the Aprilia RS 660 uses a 659 cc parallel-twin derived from the front bank of the RSV4 V4, tuned to deliver about 100 hp at 10,500 rpm and 67 Nm of torque. That gives the bike strong mid-range punch for real roads rather than only racetrack use.

The curb weight stays around 183 kg with a full tank, which keeps the RS 660 feeling light as you tip it into a roundabout or a fast mountain bend. On a short demo loop described by Italian magazine Motociclismo, riders talked about a crisp throttle response and a distinctly mechanical intake growl above 6,000 rpm that makes the bike feel alive without being harsh.

Electronics and chassis package

Aprilia equips the RS 660 with an APRC electronics suite that is unusually rich for this displacement class, including traction control, wheelie control, engine brake control, cruise control and up to five riding modes. All this is accessed through a color TFT display that stays legible even in strong sunlight.

The bike sits on an aluminum frame using the engine as a stressed member, with a sporty, slightly front-biased geometry that aims for agility rather than pure stability. Kayaba front suspension and a rear monoshock offer adjustment for preload and rebound, letting a careful owner like Milan-based rider Sara Bianchi tailor the setup for commuting, track days or weekend mountain runs.

Design, ergonomics, and daily usability

The Aprilia RS 660 design clearly references the RSV4 with triple front LED headlights, a layered fairing and a sharp tail section, but the ergonomics are milder. The clip-on handlebars are set higher and the pegs slightly lower than on a full supersport, which makes the bike more tolerable for longer rides or city traffic.

Sitting on the RS 660 in a dealer showroom, you feel a relatively narrow waist at the tank that lets your knees clamp the bike securely while still allowing shorter riders to reach the ground. The seat foam is firm but not punishing, according to early rider feedback on forums and test reports, and the small windscreen gives a noticeable pocket of calm air at 120 km/h if you tuck in.

Market positioning and variants

In Aprilia’s lineup, the RS 660 sits between the smaller 125 cc learner bikes and the high-end RSV4 superbike, effectively acting as an accessible entry point into the brand’s sport segment. It targets riders who want strong performance and electronics without the physical and financial commitment of a liter-class machine.

Several color schemes have been launched, including Acid Gold, Lava Red and Apex Black, which give dealers flexibility to match regional tastes. A Tuono 660 naked variant and the adventure-leaning Tuareg 660 share the same basic engine and platform, hinting at Piaggio’s modular strategy across Aprilia’s middleweight range.

Regulation, emissions, and licensing

The RS 660 is Euro 5 compliant, which is a crucial point for its availability in European markets from Italy to Germany. Aprilia also offers an A2-license compatible version in some countries, detuned to 95 hp and restricted to 35 kW for young riders stepping up from smaller bikes.

ABS with cornering functionality is standard, leveraging an inertial measurement unit (IMU) to adjust braking and traction support when the bike is leaned over. For safety-conscious buyers, this package is one of the most concrete reasons to pick the RS 660 over older mid-displacement sportbikes with simpler electronics.

Pricing, availability, and competition

In Italy, launch pricing for the Aprilia RS 660 was reported around 11,000 to 11,500 euros depending on trim and market specifics, putting it roughly in line with rivals like Yamaha YZF-R7 and Kawasaki Ninja 650 but with more advanced electronics. Final dealer prices can vary with local taxes and accessory packages.

The bike is distributed through Aprilia’s usual dealer network in Europe and selected markets in North America and Asia, with Piaggio using the model to strengthen the Aprilia brand’s presence among mid-range sport riders. According to comments by Piaggio Group CEO Roberto Colaninno at previous product presentations, the 660 platform is designed to scale across several models to maximize return on development and homologation costs.

Context and Piaggio & C. SpA stock

For Piaggio, the Aprilia RS 660 is not the headline revenue driver in the way that mass-market scooters are, but it plays a strategic role in keeping Aprilia relevant in the performance segment and supporting pricing power for the brand. In recent sessions, Piaggio & C. SpA stock trades in euros on Xetra and other venues, with analysts watching how the 660 platform and related models balance the more utilitarian scooter business.
