Introduction

Sporty scooter from Aprilia

The model "Aprilia - SR 50 R-Factory (2011, ZD4VFB00)" is a sporty 50cc scooter produced by the Italian manufacturer Aprilia in 2011.
As part of the renowned SR 50 lineup, this scooter combines race-inspired design with refined technology for everyday urban use and spirited riding.
The SR 50 R-Factory is aimed especially at young riders looking for an agile, eye-catching vehicle with a sporty feel.
In many countries, the model can be ridden with a moped or AM license, making it an attractive entry-level option.

History of the SR 50 series

Since its introduction in 1992, the SR 50 series has been considered a benchmark among sporty 50cc scooters.
The 2011 model year belongs to the third generation, launched in 2004 with a more angular design, improved chassis, and updated technical features.
The "R-Factory" variant was originally introduced in 2005 and is closely aligned with Aprilia's motorsport DNA – drawing visual inspiration from superbikes like the RSV.
Compared to earlier versions such as the SR 50 DiTech with direct injection, the R-Factory relies on proven carburetor technology and a liquid-cooled two-stroke engine.
In 2011, Aprilia continued this successful formula, with only minor updates in graphics, colors, or market-specific homologation.
