The wheels fitted with 17” sporty tyres make the SX one of the most effective 125cc bikes on mixed runs; lightweight and snappy, it is able to offer the emotions of a higher-powered engine capacity. SX 125 is equipped with a refined single-cylinder 125 cc engine, an Aprilia engine that has been able to further refine the four-stroke engine, allowing it to enter the strict Euro 4 standard without compromising performance or driving pleasure. With their high efficiency, increased safety, SX is equipped with advanced suspension and a new ABS braking system with anti-roll-over, which guarantees precision and total braking control and adjusts the rear wheel lift in the most decisive braking.
