Model History

The Aprilia Sonic was introduced in the late 1990s as a sport-oriented small scooter. The LC (Liquid Cooled) version represented the high-performance model, distinguishing itself from the air-cooled base variant through improved cooling and greater thermal stability.
Throughout its production run, the model received minor technical and visual updates but retained its sporty character. Production ended in 2008 as Aprilia restructured its 50cc lineup in favor of newer models.
