Rieju Mrt 50
The Rieju MRT 50 is a 50cc trials-style enduro motorcycle produced by the Spanish manufacturer Rieju, a brand founded in 1934 in Figueres, Catalonia. The MRT 50 was developed as an entry-level off-road machine aimed at young riders and beginners, combining trials-inspired geometry with practical trail riding capability. It became notable in European markets as an accessible and affordable gateway into off-road motorcycling, compliant with AM license restrictions for 16-year-olds in many EU countries.

What Buyers Should Know
Minarelli AM6 Engine
The MRT 50 uses the widely respected Minarelli AM6 two-stroke engine, meaning spare parts and performance upgrades are cheap and readily available across Europe. This makes maintenance far easier than bikes with proprietary engines.
Watch the Cooling System
The liquid-cooled AM6 variant is prone to coolant leaks and water pump wear if not regularly serviced — always check for overheating signs or milky residue before buying used. A neglected cooling system can lead to costly piston and cylinder damage.
Decent Resale Retention
The Rieju MRT 50 holds its value reasonably well in the 50cc trials/enduro segment due to its sporty image and Spanish build quality, which is generally regarded as a step above budget Chinese competitors. Buying used in good condition is relatively safe as an investment.
