Rider Profile

Best ForNote: specifications given correspond to the Rieju MR Six Days France model rather than the named MR 300 Racing, though both are closely related enduro two-strokes; this profile is best suited to experienced off-road riders, as the light weight and punchy
PurposeBuilt purely for competitive and recreational enduro riding over rough, technical terrain rather than road use.
Rider FitThe very low dry weight and tall 960mm seat height demand good rider fitness and leg length but reward the rider with exceptional maneuverability in the dirt.
CharacterA raw, high-strung two-stroke enduro weapon that thrives on aggressive throttle input and rewards an active, standing riding style.
Not Ideal ForThis is not the bike for a beginner, a passenger, a highway commuter, or anyone wanting comfort and long-distance touring ease.
