Engine & Performance

Under the bodywork sits a 659 cc parallel twin with a 13.5:1 compression ratio and an 81 x 63.93 mm bore and stroke—figures that hint at a free-revving, responsive character. Peak output is 105 hp at 10,400 rpm and 70 Nm at 8,400 rpm, giving the RS 660 the punch to rip up backroads while staying tractable in traffic. Throttle response is managed by Ride-By-Wire, and the APRC suite lets you tailor the engine feel via AEM (engine maps) and AEB (engine brake) alongside five riding modes.

For spirited riding, the 6-speed gearbox with Aprilia Quick Shift (AQS) makes clutchless upshifts and downshifts clean and quick, aided by a wet multi-plate slipper clutch that keeps the rear composed during aggressive deceleration. Traction is confidently handled by ATC (traction control), AWC (wheelie control), and ALC (launch control), all coordinated by a 6-axis IMU. The result is a middleweight that’s friendly around town, settled on the highway, and a blast when the road opens up—precisely what you want from a modern 660-class sportbike.

Handling, Comfort & Aprilia RS 660 Seat Height

Aprilia builds the chassis around a twin-spar aluminum frame and a 1381.8 mm (54.4 in) wheelbase, striking a balance between stability and agility. Suspension is provided by a Kayaba 41 mm USD fork up front (rebound and preload adjustable, 120 mm travel) and a Kayaba monoshock at the rear (rebound and preload adjustable, 130 mm wheel travel). Cast 17-inch wheels—17 x 3.5 in front and 17 x 5.5 in rear—complete the sharp-handling package.

The Aprilia RS 660 seat height is 820 mm (32.3 in), which many riders will find approachable for a sporty machine. Combined with the Aprilia RS 660 weight of 183 kg (403 lb) wet, low-speed maneuvering is predictable and confidence-inspiring. Shorter riders get a reasonable reach to the ground, while taller riders still have room to move and hang off in corners.

Equipment & Features

Braking hardware is serious: double 320 mm floating front discs with Brembo radial calipers, plus a single 220 mm rear disc with a Brembo caliper. Steel braided brake hoses help maintain a firm lever feel, and Cornering ABS adds safety when trail-braking or dealing with unexpected mid-corner surprises.

Electronics are a standout. Beyond AEM, AEB, ATC, AWC, ALC, and the 6-axis IMU, you get five riding modes to quickly change the bike’s personality. ACC (cruise control) is a welcome addition for longer rides, and Euro 5+ emissions compliance keeps it modern. Lighting is full LED, and the cockpit features a bonded 5-inch TFT display with backlit switches for easy nighttime operation.

The fundamentals are equally thoughtful: a 15 L (4.0 gal) fuel tank for daily riding, a 6-speed transmission with AQS, and a slipper clutch for smooth downshifts. Color options include Blue Marlin and Venom Yellow. Riders on restricted licenses can opt for the A2 version: a 35 kW (47 hp) variant is available.

Who Is the 2026 Aprilia RS 660 For?

The RS 660 is ideal for riders who want a lightweight sportbike with real electronics and adjustability, without stepping up to liter-bike power. As a daily rider, it’s tractable and feature-rich; as a weekend machine, it’s fast, communicative, and rewarding. Newer riders will appreciate the A2 35 kW (47 hp) option, while experienced riders will enjoy the full 105 hp with customizable APRC settings.

Torquepedia Verdict

The 2026 Aprilia RS 660 specs show a compelling blend of engine performance, chassis poise, and rider aids. Highlights include the responsive parallel twin, Brembo brakes on big 320 mm front discs, Kayaba adjustable suspension, and a top-tier electronics package with Cornering ABS, IMU-driven aids, AQS, and cruise control. The cockpit and lighting complete the premium feel.

On the flip side, the 820 mm seat height won’t suit everyone without a test sit, and the 15 L tank may encourage more frequent coffee stops on long days. Still, in the middleweight sportbike class, the RS 660 remains a benchmark for tech-per-dollar and smiles-per-mile—an easy recommendation for riders who want one bike to do it all.
