Rieju has once again proven its mettle in the hard enduro segment with the release of the MR 300i HARD ENDURO MY27. This is not just a 'dressed-up' version; it's a machine specifically designed for terrain that demands everything from both rider and engine.
Focus on Low-End Torque and Control
What's intriguing about this motorcycle is its 'slow' approach. In hard enduro, speed isn't everything. The ability to maintain power at low RPMs and provide precise control when navigating rocks, roots, and steep climbs is key. Rieju understands this, having modified the Spanish-made 298cc two-stroke TFI engine.
The addition of a flywheel weight, a water pump cover with a larger impeller, and a specific spark plug makes throttle response smoother and more manageable. This is crucial when riders need to 'creep' through tough sections or roll on the throttle to clear obstacles. Aggressive top-end power is a hindrance in hard enduro; traction and control are what matter.

Enhanced Cooling System
One of the biggest challenges in hard enduro is overheating. When speeds drop dramatically, airflow to the radiator decreases, and the engine can quickly overheat. Rieju addresses this with an upgraded cooling system: a larger capacity radiator and dual electric fans. This ensures stable engine temperatures even when the bike is crawling up steep hills or stuck in mud.
These features make the MR 300i HARD ENDURO ready for events like Erzbergrodeo or Red Bull Romaniacs. This isn't a bike for the faint-hearted; it's a weapon for riders serious about conquering nature.
With all these updates, Rieju reinforces its position as a European manufacturer unafraid to be different. The MR 300i HARD ENDURO MY27 proves that two-strokes are still relevant and can even be a top choice for the world's toughest challenges.
