About Rieju

Country of Origin: Spain
Founder: Luis Riera & Jaime Juanola
Best Known For: Lively 50–125 cc roadsters and enduros; later hard-enduro two-strokes (MR/Enduro series)

Company History

Rieju has been part of Spain’s small-displacement fabric since the 1940s, earning a reputation for agile frames and engines that make the most of limited cubic centimeters. Generations learned clutch control and line choice on Rieju 50–125s that balanced playful power with credible brakes and suspension. The brand’s modern chapter leans into enduro, where acquisitions and partnerships brought proven two-stroke platforms under the Rieju badge. Set up for Iberian terrain—rocky climbs, dusty singletrack—the MR/Enduro models emphasize tractable bottom-end, sensible gearing, and real-world protection (radiator guards, skid plates) from the factory. Rieju listens to club paddocks: jetting/EFI maps, seat foam, and lever feel evolve quickly with rider feedback. Historically, the company exemplifies Spain’s rider-centric industry—machines that teach, reward finesse, and survive hard weekends. Whether buzzing to school or threading a ravine, a Rieju feels like a willing accomplice rather than a dare, which is why the marque remains woven into the country’s off-road culture.
