Rieju is a Spanish motorcycle maker based in Figueres. It started in 1934, when Luis Riera Carré and Jaime Juanola Farrés formed a company to make bicycle accessories before moving into motorcycles. It also shows why factory data remains useful when parts, trims, or market versions differ. It also helps when sourcing correct parts for export or domestic versions.

Rieju is known for small-displacement mopeds and motorcycles, especially lightweight road and enduro models sold widely in Europe. Rieju models are often straightforward to service, which is why detailed factory information matters when a bike, scooter, or ATV needs attention after years of use. Correct identification matters because many of these machines share broad families but differ in small details from year to year. That matters especially on machines that share engines or chassis across multiple years.

The manuals here typically include engine service, gearbox and clutch repair, electrical diagrams, torque figures, carburetion or fuel injection, and scheduled maintenance. A good manual also lists wear limits, fluid types, inspection points, and other measurements that keep repairs consistent. Those pages are especially useful when a repair calls for exact measurements instead of guesswork.

They suit everyday riders, independent garages, and restorers working on older Spanish mopeds and modern small-bore motorcycles. Clear manuals save time in the shop and help keep older machines correct, complete, and roadworthy. That level of detail reduces guesswork and helps keep a machine close to factory spec. It is especially useful during rebuilds, inspections, and long-term maintenance planning.
