Introduced as the upright sibling to Aprilia’s RS 660, the Tuono 660 Factory takes the middleweight naked formula and sharpens it with higher spec components and rider aids. At just about 399 lbs wet, and producing a claimed 100 hp from its 659 cc parallel twin, it offers a strong power to weight ratio while remaining approachable and manageable on public roads. The Factory package equips the Tuono with 5 extra hp, the a-PRC (Aprilia Performance Ride Control) electronics package and upgraded Kayaba (KYB) front shocks that are fully adjustable for compression, rebound damping and preload, while the Sachs rear shock with separate reservoir is also adjustable for compression, rebound damping and preload. It also comes standard with an IMU, unlocking lean sensitive electronics such as cornering ABS, traction control, wheelie control, and customizable riding modes. A quickshifter with auto-blip is fitted from the factory, while cruise control and a 5 inch TFT dash round out the feature set. Visually, the Factory is finished in glossy black with red accents and a smoked windscreen, plus a single-seat tail cover (with pillion seat and pegs supplied).
