Rieju Enduro MR 300i Racing 2027 2T TFI
The Rieju MR 300i Racing 2027 is a 2-stroke Enduro motorcycle developed around Rieju’s new 298 cc engine with TFI electronic fuel injection. This system uses two separate Bosch injectors to operate at low and high engine speeds, combining the direct response of a 2-stroke engine with electronic fuel management.
The rider can adjust the engine’s power delivery using three engine maps: Race, Forest and Wet. These are complemented by an electronic power valve, a counter-rotating balance shaft and a diaphragm clutch, components designed to improve response control, reduce vibration and make power easier to regulate over technical terrain.
The chassis combines a chrome-molybdenum steel frame with long-travel KYB suspension, 21- and 18-inch Excel rims, Mitas Terra Force-EF tyres and Nissin brakes with Galfer discs. For the 2027 season, it features dedicated Racing graphics and the new LED headlight used across the MR range.
