Aprilia Launches Upgraded RS 660 Factory with Enhanced Engine and Chassis – Limited to 12 Units

Piaggio Group Japan Co., Ltd. (Head office: Minato-ku, Tokyo, Representative Director: Lerch M. Kenji) announces the launch of the upgraded Aprilia RS 660, a benchmark in the middleweight sports motorcycle category. The new 'RS 660 Factory' features high-performance Ohlins suspension and premium equipment, with orders opening nationwide at authorized Aprilia dealerships starting July 14, 2026.

The upgraded RS 660 now incorporates race-derived aerodynamic winglets, a power increase to 105HP from its 660cc twin-cylinder engine, and an even more advanced electronic control package. Additionally, the 'Factory' model features front and rear Ohlins suspension, delivering accessible everyday riding for beginners while offering experienced riders an exhilarating track-focused experience.

Aprilia RS 660 Factory

The RS 660 is engineered using racing technology developed through Aprilia’s experience in world championships, designed to enhance the joy of riding on public roads. With a mere 183kg wet weight and the advanced APRC electronic control system, it achieves the ideal balance for a middleweight supersport. The RS 660 perfectly blends innovation, technology, and design, embodying the true essence of the Aprilia brand.

Latest Aerodynamics

Since its debut, the Aprilia RS 660 has defined a new category of motorcycles, setting the benchmark in its segment. This well-received project continues to evolve with a focus on higher refinement. By incorporating aerodynamic solutions typically reserved for 1000cc-class superbikes, Aprilia reaffirms its leadership in this field. The fairing has been completely redesigned, maintaining the core concept of a dynamic and modern shape composed of compact surfaces, while integrating insights gained from Aprilia’s MotoGP participation for enhanced aerodynamics. A large wing is newly positioned beneath the front fairing, and two smaller aerodynamic components contribute to reduced air resistance and improved high-speed stability.

The newly designed side fairings inherit the innovative double-layer structure with integrated aerodynamic parts, seamlessly blending design and functionality. The effectiveness of this solution was first analyzed using CFD (Computational Fluid Dynamics) software, followed by wind tunnel testing, and ultimately verified through real-world testing on public roads and circuits. The goal was to protect the rider from wind pressure during riding and efficiently manage heat flow from the engine and radiator, simultaneously enhancing performance and rider comfort.

Advanced Electronics

The Aprilia RS 660 also advances in electronics. It now features new handlebar switches with backlighting and a larger 5-inch full-color instrument panel, improving brightness and reducing glare, enabling the display of more information and enhancing overall equipment quality.

One of the defining features of the Aprilia RS 660 is its electronic control system, designed to enhance both performance and safety. Since its first generation, it has featured the most comprehensive system in its class, surpassing even superbike-level machines.

Aprilia has consistently led in electronic control technology (pioneering ride-by-wire throttle systems globally in 2007) and now equips the full-spec APRC (Aprilia Performance Ride Control) electronic control package. Developed with top-level racing in mind, this system is widely acclaimed by users and critics as one of the most advanced systems available.

The new Aprilia RS 660’s APRC system now includes 'Launch Control,' a standing-start management system commonly used on race bikes. This complements the already comprehensive suite of features, including ATC (adjustable on/off traction control), AWC (adjustable on/off wheelie control), ACC (cruise control that maintains set speed without throttle input), AQS (bidirectional quick shifter), AEB (adjustable engine brake control), and AEM (multiple engine maps to change power characteristics). As before, the RS 660 comes standard with electronic ride-by-wire throttle and a 6-axis inertial measurement platform. This platform uses accelerometers and gyroscopes to detect the bike’s attitude relative to the road surface, recognizes rider inputs, and sends data to the ECU to adjust control parameters as needed. Additionally, it features multi-map cornering ABS, which optimizes brake and ABS operation during cornering through dedicated algorithms. This algorithm continuously monitors parameters such as lateral acceleration, front brake lever pressure, lean angle, pitch angle, and yaw angle, controlling brake operation to optimally balance deceleration and stability.

Engine Balancing Environmental Performance and Performance

The compact and lightweight 660cc parallel twin-cylinder engine, a latest-generation unit, has already delivered record-breaking performance in its class. It now meets the stricter EURO 5+ emissions standard. By increasing the throttle body diameter (from 48mm to 52mm), the RS 660’s output has increased from 100HP to 105HP. This engine also functions as a stressed member, combining with a twin-spar frame bolted to the steering head and rear section, achieving a compact, lightweight, and highly rigid chassis structure based on Aprilia’s traditionally refined chassis design philosophy.

No Compromise in Components

Since the launch of the 660 series, the long-awaited 'RS 660 Factory' has finally arrived.
