Model Description

The model "Aprilia - SR 50 R-Factory (2008, ZD4VFB00)" is a sporty scooter produced by the Italian manufacturer Aprilia in 2008. It belongs to the SR 50 series, known since 1992 for its innovative technology and dynamic design. The SR 50 R-Factory was developed to offer riders in the 50cc class a powerful option with a racing character, suitable for both urban use and sporty rides. This model is aimed primarily at riders looking for a nimble vehicle with a distinctive appearance that can be ridden in many countries with a moped or AM license.

History of the SR 50 Series

The SR 50 series was first introduced in 1992 and quickly established itself as a pioneer in the scooter segment. The SR 50 R-Factory (2008, ZD4VFB00) belongs to the third generation of this model family, which was launched from 2004 with a new design and technical improvements. The "R-Factory" variant was introduced from 2005 and stands out due to its proximity to Aprilia's racing DNA, inspired by models like the RSV 1000. Compared to earlier SR models, such as the SR 50 DiTech (from 1999), the R-Factory version places more emphasis on sporty looks and chassis components while retaining the proven two-stroke technology. In 2008, Aprilia competed with brands like Yamaha and Piaggio, relying on a combination of performance and aggressive design to reach the target audience of younger riders and enthusiasts.
