The Rieju RS3 125 stands as the flagship of the Spanish manufacturer's small-displacement sportbike lineup. The 2026 model features a liquid-cooled, 4-valve engine developed through the Yamaha-Minarelli partnership, now fully compliant with Euro 5+ emission standards. Delivering a full 15 horsepower, it hits the legal limit for A1 license holders, providing class-leading performance. Its chassis is a dual steel perimeter beam design, developed in collaboration with ArianeTech, ensuring exceptional stability at high speeds. The bike is equipped with premium hardware, including 41mm inverted (USD) front forks and a radial-mount front brake caliper paired with a 280mm disc. Beyond performance, the RS3 125 offers a true racing aesthetic with its dual projector headlamps and sharp, aerodynamic fairings. The digital instrument cluster provides clear information, including gear position and engine RPM. Thanks to its lightweight construction, it remains agile in urban traffic while offering precise handling on twisty backroads, making it a top choice for aspiring sport riders.
