Rieju MR 300i Hard Enduro 2027 2T TFI
The Rieju MR 300i Hard Enduro 2027 is the most highly equipped and specialised version in the MR 300i range. It has been developed for extreme climbs, rocky sections and slow, technical terrain where manageable response, strong traction and additional motorcycle protection are required.
It is based on the 298 cc single-cylinder 2-stroke engine with TFI electronic fuel injection, but adds modifications specific to the Hard Enduro version. These include an inertia sleeve, a Hard water-pump cover with a higher-flow impeller, a dedicated spark plug and an exhaust developed to improve drive and traction at low revs.
Cooling is reinforced by a dedicated expansion tank and a twin electric fan module. It also features short gearing with an 11-tooth front sprocket, a red AXP chain guide, competition protection, repositioned footrests and front and rear pull straps to facilitate manoeuvres in extreme sections.
