Introduction

Model Description

The model "Aprilia - SR 50 Street (2008-2010, ZD4TEA)" is a sporty scooter produced by the Italian manufacturer Aprilia between 2008 and 2010. It belongs to the SR 50 series, known since 1992 for its innovative technology and dynamic design. The SR 50 Street was developed to offer riders in the 50cc class a powerful and agile option, particularly suited for urban use. This model is aimed at riders seeking an agile 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 Street (2008-2010, ZD4TEA) belongs to the third generation of this model family, introduced in 2004 with a new design and technical improvements. Compared to earlier models like the SR 50 DiTech (from 1999), which relied on direct injection, the SR 50 Street returned to a classic carburetor system while maintaining the sporty orientation of the series.

Market Positioning

From 2008 to 2010, Aprilia positioned itself in competition with brands like Yamaha and Piaggio, aiming to reach the target group of younger riders with a mix of performance and style. The "Street" as a base version differs from higher-end variants like the SR 50 R or R-Factory through simpler equipment but remains true to the sporty line.
