Introduction

The model "Aprilia - SR 50 Di-Tech (2004–2007, ZD4VF0)" is a sporty high-tech scooter from the Italian brand Aprilia, equipped with direct injection technology and designed especially for eco-conscious urban riders.
With its striking design and advanced engineering, it belongs to the second generation of Di-Tech models that Aprilia has been producing since 2000, focusing on efficiency and reduced emissions.

Technological Advancement

The ZD4VF0 is based on the proven Orbital Di-Tech technology, which uses an air-assisted injection system to inject fuel directly into the combustion chamber.
This solution reduces fuel consumption and already met tightened emission standards at the time, without compromising riding fun.
The model also features new, more aggressive bodywork and an updated cockpit with digital instrumentation.
The blend of technology, design, and everyday usability made the Di-Tech VF0 especially attractive to young urban riders.
