Rider Profile
| Best For | Note: 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 |
| Purpose | Built purely for competitive and recreational enduro riding over rough, technical terrain rather than road use. |
| Rider Fit | The 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. |
| Character | A raw, high-strung two-stroke enduro weapon that thrives on aggressive throttle input and rewards an active, standing riding style. |
| Not Ideal For | This is not the bike for a beginner, a passenger, a highway commuter, or anyone wanting comfort and long-distance touring ease. |
