The Aprilia RS 660 is a compelling option for those seeking a balance of performance, agility, and advanced technology. With its 659cc parallel-twin engine producing 100 horsepower at 10,500 rpm and 49.4 lb-ft of torque at 8,500 rpm, it offers exceptional power-to-weight ratio, given its lightweight design of just 403 pounds. The bike features a robust APRC electronics package, including traction control, wheelie control, engine-braking control, and cornering ABS, making it versatile and safe for various riding conditions. The ergonomic design, with a relatively high handlebar position and low-and-forward footpeg placement, makes it comfortable for everyday riding while still delivering a sporty experience. Additionally, the bike's advanced suspension, Brembo brakes, and configurable ride modes enhance its overall performance and usability. However, it comes at a premium price, starting at $11,549, which may be a consideration for some buyers. Overall, the Aprilia RS 660 is worth buying for those who value its unique blend of performance, technology, and comfort.
