The Aprilia RS 125 is a true marvel of modern motorcycling engineering, boasting an impressive array of features and performance capabilities for its class. Powered by a high-tech liquid-cooled two-stroke engine, this 125cc single-cylinder marvel delivers over 194kW (260bhp) per liter, thanks to advanced intake and exhaust designs.
The RS 125’s aerodynamic fairing is a stunning homage to the world of Grand Prix racing, while its high-specification chassis design features wide, sporty tires and premium components such as 40mm upside-down front forks and an adjustable monoshock rear suspension. This potent combination comes together to create a riding experience that is both exhilarating and precise.
Riding the Aprilia RS 125 is akin to piloting a miniature Grand Prix machine, its agile handling and rapid acceleration making it a true thrill ride on twisty roads or the track. As one of the last remaining performance two-stroke motorcycles in production, the RS 125 is an heir to a proud legacy that spans decades of innovation and passion in motorcycling.
