The Aprilia C361M, along with its close relatives the C364M and C216M, represents a pivotal moment in the Italian manufacturer's history. These light, agile machines were intended for the burgeoning scooter market, a segment that Aprilia had previously largely ignored. Launched in 2004, these scooters boasted a modern, sporty aesthetic, drawing heavily from the design language of Aprilia's successful motorcycle range. The C361M, powered by a 125cc liquid-cooled four-stroke engine, was the entry-level model, offering a balance of performance and practicality. The C364M, with its slightly larger 180cc engine, provided more power for longer journeys or carrying a passenger. Finally, the C216M, powered by a 200cc engine, aimed at those seeking the most spirited performance. All three models shared a lightweight, tubular steel frame, ensuring nimble handling and agility, a feature that became synonymous with Aprilia scooters.

Beyond the engine size, the C361M, C364M, and C216M offered a range of features that appealed to both commuters and leisure riders. The scooters were equipped with telescopic front forks and twin rear shock absorbers, contributing to a comfortable ride. A large, under-seat storage compartment provided ample space for carrying everyday essentials, while a convenient front glovebox offered additional storage for smaller items. The scooters featured a digital instrument panel displaying all the essential information, including speed, fuel level, and a clock. These details, combined with the relatively low price point, made the C361M, C364M, and C216M attractive options for those looking for a practical, stylish, and fun way to navigate urban environments. While production of these models ended in 2007, they left a lasting mark on Aprilia's scooter legacy, paving the way for future models like the SR series and solidifying the brand's reputation for delivering high-performance, rider-centric scooters.
