Introduction

General Information

The SR 50 models were developed to appeal primarily to younger riders seeking a powerful and agile vehicle for urban use in the 50cc class, which can be ridden in many countries with a moped or AM license.
The "LC" designation stands for "Liquid Cooled," highlighting the liquid-cooled engine design, which was a technological advancement at the time.

History and Development

The SR 50 series was first introduced in 1992 and set new standards in the sporty scooter segment.
The ZD4LC, built from 1995 to 1996, belongs to the first generation of this model family, characterized by its innovative technology and aggressive appearance.
With the introduction of the SR 50, Aprilia established a sporty scooter that clearly stood out from the competition.
The liquid-cooled variant from 1994 marked an important step, as it offered better power delivery and thermal stability than the earlier air-cooled models.
During this phase, Aprilia positioned itself in competition with brands like Yamaha and Piaggio and further built its reputation as an innovator in the scooter market.
The ZD4LC was part of this development and targeted riders who valued performance and modern design.
