aprilia SX 125



The SX 125 is distinctive motorcycle with high level performance and design. It’s the only bike in this segment to sport a front wheel-only ABS braking system. The SX 125 is the product of Aprilia’s success in off-road competitions and this updated model boasts a sophisticated design, powerful performance, and advanced technology that makes this the bike for people who want to stand out from the crowd right from the start of their life on two wheels. The SX offers great riding satisfaction to anyone climbing on-board.

Top level chassis

Safety on the Aprilia SX is provided by advanced suspension and a new top-level braking system with front wheel-only ABS that ensures great power and modulation for excellent braking performance. With the goal of increased safety and better efficiency, Aprilia is the first manufacturer to introduce the Bosch front wheel-only ABS system with anti-rollover mode in this market segment - a system that offers total braking control and mitigates rear wheel lift under heavy braking.

The single-cylinder 125cc

A state-of-the-art single-cylinder 125cc engine is the heart and soul of the Aprilia SX 125; it’s a lightweight single-cylinder motor that easily reaches the maximum power ceiling for this displacement and delivers exhilarating acceleration. The engine is a classic example of how technology developed in competitions can not only obtain benchmark performance but also make for extremely clean engines. 

Sophisticated digital instrumentation

Confirming its wish to build advanced motorcycles that are versatile and practical during everyday use, Aprilia has equipped the SX with sophisticated, compact, modern and easy to read digital instruments. In addition to the common functions, the digital dashboard also offers a travel diary, with the ability to view top speed, battery voltage, and with two trip meters indicating the distance travelled during riding sessions.
