Introduction

Aprilia SR 50 Di-Tech (2012, ZD4TE)

The sporty scooter was produced by the Italian manufacturer Aprilia in 2012. It belongs to the SR 50 series, which has been known for its innovative technology and dynamic design since its introduction in 1992. The SR 50 Di-Tech was developed to offer riders in the 50cc class a powerful yet more environmentally friendly alternative, particularly through the use of direct injection technology.
This model is primarily aimed at younger riders or commuters looking for a nimble vehicle with a sporty character 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 set early standards in the scooter segment. The SR 50 Di-Tech (2012, ZD4TE) belongs to the third generation of this model family, which made a technological leap from 2000 with the introduction of Di-Tech technology (Direct Injection Technology). This technology was developed in collaboration with Orbital and marked the beginning of injection in 50cc scooters in 1999.
The ZD4TE from 2012 is a further development of this concept, characterized by optimized engine management and adaptation to stricter emission standards like Euro 3. At this stage, Aprilia already had a firm place in competition with brands like Piaggio and Yamaha, relying on the combination of performance and efficiency to serve the market.
