A brief history of the Rieju marque
Luis Riera and Jaime Juanola began building bicycle components in 1934 under the brand formed from their surnames, Rieju. After the Spanish civil war business resumed at their factory in Figueres, Alt Empordà, and in 1942 a company was formed named Riera & Juanola RL, now making complete bicycles.
In 1945 they began importing Serwa bicycle attachment engines (or possibly building them under licence) for their first powered machines, the "Autociclo", which they built in 32cc to 50cc versions.
These were followed by motorcycles powered by 175cc AMC four-stroke engines, first appearing in 1953.
Over the following years a good variety of mopeds, motorcycles and scooters were released, almost all of which were powered by the two-stroke AMC engines.
The Rieju Jaca sports moped powered by a 50cc Minarelli engine appeared in 1964. These engines were built under licence by Rieju, and the model proved a great success.
From the 1980s to the mid-1990s the firm built Malaguti machines under licence, models including the F10, F12, Crosser and RST.
The Marathon was offered from 2007 using Yamaha WR 250 and 450 engines in a Gas Gas frame. There was also a model with a 125cc Yamaha engine.
Electric motorcycles were introduced in 2012, in conjunction with Ossa and Gas Gas. This project progressed further in 2015 when a consortium of firms formed an agreement with the Catalan authorities.
Rieju models include:
Type: Enduro, 250cc Marathon 125 pro 2010-

Even when the engine is idling it generates very high heat. The head light also heats up very fast. The bike has just come out from the show room.

Rieju 2005 RS-1 Castrol 50
I am looking for bodyworks for the above bike. HELP PLEASE!!! I have been trying with no luck to find parts for this bike.
Thank you for your reply. I have attached photos of the bike in question,
a 2005 Rieju RS-1 Castrol 50. I need all original bodyworks fairings! I
would assume that they are sold in the base colors and then a graphic
package would need to be applied by me. We need the graphic package as well
as that is pretty much what makes this bike unique. Your help is much

Rieju Tango 50cc 2007 model
please advise on lubrication of this engine as handbook only shows engine/gearbox sump dont 2 strokes normally have a seperate header tank for the engine?
Sorry I do not have pictures but bike can be found on Rieju website, I have been back to the supplier who showed me the oil tank is situated under the seat as per most 2 strokes and it also has a low oil warning light on the digital speedo/dash, this information is not printed in the handbook.
The bike has now done 600kms and had its first service, I have done the first stage derestriction which involves seperating the exhaust manifold (header pipe) from the expansion chamber and removing a restrictor plate then changing the main jet from a 75 to 95, it will now do 75kmh/45mph and pulls strongly
next stage derestrict will be soon
If you have a query or informaton about Rieju motorcycles please contact us
