The Aprilia Tuono V990, produced from 2002 to 2005, is a naked sport motorcycle that redefined the segment with its aggressive styling, potent engine, and raw riding experience. Built upon the platform of the renowned RSV Mille superbike, the Tuono V990 inherited its 998cc, 90-degree V-twin engine, a powerhouse capable of delivering over 125 horsepower. This engine, mated to a six-speed transmission, propelled the Tuono to thrilling performance, making it a formidable contender on both the road and the track. Beyond its impressive power, the Tuono boasted cutting-edge technology for its time, including a trellis frame designed by renowned engineer, Mauro Lucchi, and Showa suspension components for responsive handling. This combination of power and handling allowed the Tuono to carve through corners with precision and agility. The Tuono V990 was available in two variants: the standard model and the more focused Factory version. The Factory model featured upgraded suspension, brakes, and wheels, enhancing its performance and track capabilities. The Tuono V990, despite its performance-oriented nature, offered a comfortable riding experience for both everyday commutes and longer journeys. The upright riding position and relatively forgiving ergonomics provided a balance of sportiness and comfort. It also featured practical aspects like a comfortable seat, a digital instrument panel, and decent storage space under the seat. The Tuono V990 became a cult classic among motorcycle enthusiasts, praised for its unique blend of style, performance, and practicality. Its potent engine, refined handling, and aggressive design made it a highly sought-after machine, cementing its place as a true legend in the world of naked sport bikes. Despite being discontinued in 2005, the Tuono V990 remains a popular choice for collectors and enthusiasts alike, its legacy continuing to inspire future generations of performance-focused motorcycles.
