Aprilia RX 125 (2021)

The latest offspring of Aprilia’s storied off-road racing heritage, the SX 125 and RX 125, have been reborn with a vengeance. Fuel injection and sophisticated ECU electronics come together in perfect harmony to deliver exceptional performance, while the Magneti Marelli MIUG4 engine roars to life with increased power and punch.

The design, too, has undergone a radical makeover, inspired by the iconic Aprilia off-road motorcycles that forged a new trend in the sport. The result is a sleek, aggressive aesthetic that’s as attention-grabbing as it is functional.

But what truly sets these bikes apart is their ability to deliver unparalleled riding satisfaction on both paved roads and treacherous off-road trails. With top-shelf sports content and razor-sharp handling, young riders will be spoiled for choice when tackling the most demanding terrain with the SX 125’s road-ready poise or the RX 125’s fearless off-road prowess. The wait is over: Aprilia has unleashed its ultimate entry-level offerings on an unsuspecting world.
