Rider Profile

Best ForNote: specifications given are for the Rieju MR Six Days France, a closely related model, not the exact MR 300 Ranger, so figures should be treated as broadly representative rather than exact; this is a machine best suited to experienced or committed inte
PurposeBuilt purely for serious enduro and off-road competition or trail riding, not for road use or commuting.
Rider FitIts 960mm seat height and 105kg dry weight demand a taller rider with decent leg strength and off-road fitness, though the light overall mass makes it manageable for maneuvering compared to bigger dual-sports.
CharacterA raw, high-strung two-stroke enduro weapon that rewards active riding, clutch and throttle finesse, and technical trail skill over outright speed or comfort.
Not Ideal ForThis is not the bike for new riders, daily commuters, highway touring, or anyone wanting a comfortable passenger-friendly machine.
