Introduction

The model "Aprilia - SR 50 AC (1994-1996, 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 made a name for itself with its dynamic design and innovative technology.
The SR 50 was developed to appeal primarily to younger riders looking for a nimble and powerful vehicle in the 50 cc class, which can be ridden in many countries with a moped or AM license. The designation "AC" stands for "Air Cooled" and highlights the air-cooled design of this model.

Development and Design

The SR 50 series debuted in 1992, marking Aprilia's entry into the market of sporty small motorcycles. The Type 78, produced from 1994 to 1996, belongs to the early phase of this model family and represents an evolution of the original design.
While the first models from 1992 started with a rather simple approach, the version from 1994 brought a refined look and technical adjustments. Aprilia early on focused on sporty aesthetics and innovative features with the SR series, setting it apart from competitors like Gilera or Peugeot.
The SR 50 AC (1994-1996) falls into a time when Aprilia solidified its reputation as a pioneer in the scooter segment, shortly before the series was further expanded with models like the liquid-cooled SR 50 LC (from 1994).

Technical Specifications

Technically, the Aprilia SR 50 AC (1994-1996, Type 78) is powered by a single-cylinder two-stroke engine with a displacement of 49 cc. The engine is air-cooled and fueled by a carburetor, enabling a power output of about 3.2 kW (4.3 hp) at 6,500 rpm.
The top speed is limited to about 45 km/h, with unrestricted variants potentially reaching higher values depending on approval. The vehicle features a continuously variable CVT transmission, ensuring easy handling and smooth power delivery.

Chassis and Brakes

The chassis consists of a hydraulic telescopic fork at the front and a single shock absorber at the rear, providing the scooter with stable road holding and adequate comfort.
The braking system includes a 190 mm diameter disc brake at the front and a 110 mm drum brake at the rear, which offered solid braking performance for this class at the time.
With a dry weight of about 89 kg and a wheelbase of 1,270 mm, the SR 50 AC is light and agile, ideal for city traffic. The tires, measuring 130/60-13 at the front and rear, ensure good grip and emphasize the sporty character.

Color Variants and Special Models

The Aprilia SR 50 AC (1994-1996, Type 78) was available in various color variants, which could vary depending on the market. Typical paint finishes include "Rosso" (Red), "Nero" (Black), and "Blu" (Blue), which emphasized the dynamic style of the scooter.
There are no clear indications that official special models were produced for this specific model. Although the SR series was known for later introducing limited editions like the "Racing" or "Replica" variants, the focus for Type 78 was on a uniform series production for a broad customer base.
Individual customizations might have been offered by dealers without being considered official special models.
