In a world obsessed with horsepower wars, Aprilia asked a different question: what if you could have thrilling performance, sophisticated electronics, and razor-sharp handling in a package that doesn’t intimidate? The RS 660 answers that question brilliantly, offering 105 HP of Italian twin-cylinder perfection in a chassis that rewards skill over bravado.
The RS 660’s 659cc parallel twin produces 105 HP at 10,400 rpm and 70 Nm of torque at 8,400 rpm—figures that might seem modest until you consider the bike’s lightweight 183 kg wet weight. This power-to-weight ratio means explosive acceleration and flickable handling that makes every road feel like a racetrack. The engine is smooth, linear, and incredibly responsive, with a character that encourages you to explore the full rev range.
Unlike bigger bikes that can overwhelm, the RS 660 delivers performance you can actually use on real roads. The quickshifter makes gear changes seamless, while the broad torque curve means you’re always in the powerband.
Aprilia didn’t cut corners on electronics. The RS 660 features the full APRC suite with five riding modes, cornering ABS, traction control, wheelie control, launch control, and cruise control—all managed through a gorgeous 5-inch TFT display. This is world-class technology at a middleweight price point, giving you the confidence to ride faster while staying safer.
The Kayaba suspension is fully adjustable at both ends, letting you dial in the perfect setup for your riding style, while Brembo radial calipers provide stopping power that’s both powerful and progressive.
The RS 660 looks every bit the supersport it is. Sharp, aerodynamic bodywork with LED lighting and that signature Aprilia triple headlight design creates an aggressive stance. The compact dimensions and low 820mm seat height make it accessible, while the race-inspired ergonomics put you in perfect position to attack corners.
The RS 660 is the ideal bike for riders who want serious performance without the intimidation factor of a litre-class superbike. It’s perfect for canyon carving, trackdays, or spirited street riding. Whether you’re an intermediate rider looking to level up or an experienced rider who values precision over outright power, the RS 660 delivers engagement and excitement in equal measure.
