Introduction

The model "Aprilia - SR 50 AC (1993–1996, Type 78)" is a sporty scooter produced by the Italian manufacturer Aprilia between 1994 and 1996. It belongs to the first generation of the SR 50 series, which was introduced in 1992 and quickly gained a reputation for its dynamic design and innovative technology.
The SR 50 was developed primarily to appeal to younger riders looking for a nimble and powerful vehicle in the 50 cc class that could be ridden with a moped or AM license in many countries. The designation "AC" stands for "Air Cooled" and emphasizes the air-cooled construction of this model.

Development and Design

The SR 50 series debuted in 1992 and marked Aprilia's entry into the market for sporty small-displacement scooters. Type 78, produced from 1993 to 1996, belongs to the early phase of this model family and represents an evolution of the original design.
While the first models launched in 1992 had a rather simple appearance, the version introduced from 1993 brought refined styling and technical adjustments. With the SR series, Aprilia embraced sporty aesthetics and innovative features early on, which set it apart from competitors like Gilera and Peugeot.
The SR 50 AC (1993–1996) falls within a period in which Aprilia solidified its reputation as a pioneer in the scooter segment, just before the range was expanded with models like the liquid-cooled SR 50 LC (from 1994 onward).

Technical Specifications

Technically, the Aprilia SR 50 AC (1993–1996, Type 78) is powered by a single-cylinder two-stroke engine with a displacement of 49 cc. The engine is air-cooled and fuelled via a carburetor, delivering approximately 3.2 kW (4.3 hp) at 6,500 rpm.
The top speed is limited to around 45 km/h, while derestricted versions could reach higher speeds depending on approval and regulations. The vehicle features a continuously variable transmission (CVT), allowing for easy handling and smooth power delivery.

Chassis and Brakes

The chassis consists of a hydraulic telescopic fork at the front and a single rear shock absorber, offering stable road handling and sufficient comfort.
The braking system includes a 190 mm disc brake at the front and a 110 mm drum brake at the rear, which provided solid braking performance for this class at the time.
With a dry weight of around 89 kg and a wheelbase of 1,270 mm, the SR 50 AC is lightweight and agile—ideal for urban riding. The 130/60-13 tires at the front and rear ensure good grip and highlight the scooter’s sporty character.

Color Variants and Special Editions

The Aprilia SR 50 AC (1993–1996, Type 78) was available in various color options, which could vary depending on the market. Common paint finishes included "Rosso" (Red), "Nero" (Black), and "Blu" (Blue), which emphasized the scooter’s dynamic style.
There are no clear indications that official special editions were produced for this specific model. While the SR series later became known for limited editions such as the "Racing" or "Replica" variants, the Type 78 focused on standardized production aimed at a broad customer base.
However, individual customizations may have been offered by dealers, even though they were not considered official special editions.
