The Aprilia RX 125R is a potent blend of Italian engineering and high-performance design. Its single-cylinder, two-stroke engine packs a punch, thanks in part to the Rotax 123 powerplant and the innovative Gilardoni 2 cylinder/head setup. This potent combination delivers a thrilling riding experience, with instant throttle response and a willingness to rev that’s hard to resist.
Riding the RX 125R is an exercise in finesse, as the bike’s agility and handling make it equally at home on twisty roads or tight urban environments.
The result is an exhilarating ride that puts riders firmly in control – the Aprilia RX 125R is a true thrill-seeker’s delight.
