What Aprilia RS 660 Is and How It Works

The Aprilia RS 660 is a supersport motorcycle powered by a 659cc parallel-twin engine producing 100 horsepower at 10,500 rpm and 49.4 lb-ft of torque at 8,500 rpm. This liquid-cooled unit features Aprilia's signature 270-degree crankshaft for authentic character and strong low-end pull.

Its chassis combines an aluminum twin-spar frame with a high-performance suspension setup: a 41mm upside-down Showa fork adjustable for preload, compression, and rebound, paired with a Sachs rear monoshock offering similar adjustments. Braking comes from Brembo Stylema calipers gripping 320mm front discs and a 220mm rear disc, with cornering ABS and traction control as standard.

Electronics shine with a 5-inch TFT display, six-axis IMU, and riding modes including Race, Track, Sport, Street, and Rain. Features like wheelie control, engine brake control, and cruise control enhance usability across scenarios.

Why Aprilia RS 660 Matters for Consumers and Industry

For riders, the RS 660 delivers superbike thrills in an accessible 403-pound wet weight package, making it ideal for both track days and canyon carving. Its ergonomics suit a wide range of body sizes, with clip-on handlebars and a sporty yet comfortable riding position.

In the industry, it exemplifies Aprilia's push into premium middleweights, competing against the Yamaha R7 and Kawasaki ZX-6R while offering superior electronics and Italian design flair. The model's success underscores demand for versatile sportbikes that excel on road and track.

Owners praise its refined power delivery and confidence-inspiring handling, with real-world mileage around 45 mpg supporting longer rides.

Available worldwide, the RS 660 starts at around $11,500 in the US, with on-road prices in India reaching $18,500 including taxes and fees. Variants like the Factory and Extrema models add premium suspension and aero packages for track-focused buyers.

Competition remains fierce, but the RS 660's electronics edge and build quality help it carve a niche. Supply chains benefit from Piaggio Group's manufacturing scale, ensuring steady availability despite global disruptions.
