Aprillia RX 125

Aprillia RX 125

The world-beating styling, performance and technology of these fantastic machines has engendered a family of eye-catching and modern off-road motorcycles. The SX 125 and RX 125 are the latest off-road machines from Aprilia. Specialist and refined, they are the obvious choice for young riders who want to stand out right from the very start.  The SX and RX are both built to deliver total rider satisfaction.  Though the technology is basically the same, it has been adapted to match the different specialities. The SX and RX share the same body, frame, engine and suspensions but have very different characters for very different passions.

With its 17” wheels and sports tyres, the SX is the obvious candidate for the prize of the meanest 125 over mixed routes. Nippy and lightweight, the SX delivers real ‘big bike’ performance without exceeding the power restrictions imposed by law. Its refined, sprightly engine never lets you down.

The RX and the SX 125 also share a clear Aprilia family look, obviously inspired by their bigger sisters, machines that have established a whole new trend in off-road design.
