Key specifications
Overview
Introducing the 2010 Aprilia RS 50, a striking figure in the sport motorcycle category that embodies the essence of racing heritage and youthful exuberance. Designed for entry-level riders and seasoned enthusiasts alike, the RS 50 stands out with its bold aesthetics, inspired by its larger, more powerful siblings in the Aprilia family. With a combination of lightweight construction and agile handling, this compact sportbike offers a thrilling introduction to the world of motorcycling while maintaining the high-performance standards for which Aprilia is renowned. At the heart of the RS 50 lies a potent 49.90 ccm single-cylinder, two-stroke engine that delivers exhilarating performance for its class. With a compression ratio of 11.5:1 and a finely-tuned Dell Orto VHST 28 carburettor, this powerplant strikes a perfect balance between power and efficiency. The six-speed gearbox enables riders to harness the engine's full potential, while the multi-plate clutch ensures smooth gear transitions, enhancing the overall riding experience. The liquid cooling system maintains optimal temperatures even during spirited rides, allowing the RS 50 to perform reliably on both city streets and twisty backroads. Beyond its impressive engine, the RS 50 is equipped with a sloping twin-spar frame crafted from thin-walled cast aluminum, providing rigidity without excess weight. The 40 mm upside-down front forks offer exceptional front-end feedback, while the rear suspension features a double-reinforced aluminum swingarm that contributes to precise handling and stability. Stopping power is equally impressive, thanks to the 300 mm front disc and 180 mm rear disc brakes that ensure reliable performance in any riding scenario. With a fuel capacity of 13 liters, the RS 50 is designed for spirited rides that can last, while its electric starter adds convenience for daily use. **
