History of the SR 50 Series

The SR 50 series was introduced in 1992 and quickly established itself as a pioneer in the sporty scooter segment.
The SR 50 R-Factory (2004-2005, ZD4VF0) belongs to the second generation, which was launched in 2004 with a revised design and technical improvements.
This generation featured a sharper look, inspired by Aprilia's superbikes like the RSV 1000, and focused on a combination of performance and style.
The "R-Factory" designation distinguishes this model from the base version SR 50 R by offering higher-quality components and a more direct connection to racing.
During this phase, Aprilia solidified its position in competition with brands like Yamaha and Piaggio, with the SR series having already attracted attention through innovations such as liquid cooling and direct injection.
