Model Description

Designed for the most demanding and sports-oriented younger riders

The Aprilia SX 125 makes a statement with its top of the range sports features, outstanding performance and distinctive design. It is also the only bike in this segment to boast ABS with anti-rollover, which is fitted on the front wheel. Heir to Aprilia’s successful history in off-road competition, the SX 125 benefits from advanced technology that makes it a true contender for two-wheeler debutants with serious aspirations.

The Aprilia SX is quite simply one of the most efficient 125 bikes on the road. Lightweight and agile, it sets the benchmark in the category, in no small part due to its engine. An authentic Aprilia motorbike, its design and performance are guaranteed to get the adrenalin flowing as soon as you take hold of the handlebar.

Sophisticated digital instrumentation

Demonstrating the commitment to developing advanced, versatile bikes that are practical for everyday use, the Aprilia SX is equipped with a sophisticated, modern digital instrument panel that is compact and easy to read.
