Aprilia RS4 50

In 2011, the Aprilia RS4 50 was introduced as the successor to the RS 50 and represented a real revolution in the 50cc sportbike segment. This generation not only introduced an engine compliant with the Euro 3 standard, but also adopted a design and chassis directly inspired by the RSV4 superbike. Key improvements include a perimeter frame made of aluminum alloy, an upside-down fork, and a braking system with radial brake caliper. It became a true technical benchmark both on the road and, thanks to the wide range of available tuning parts, on the track.
