Rieju Unveils Fuel-Injected 2026 MR 300i Models

Rieju has officially announced its 2026 MR 300i Racing and Pro models, marking the most significant update to their enduro platform since acquiring the former GasGas technology. The headline feature is the new Throttle Body Fuel Injection (TFI) system, developed in-house in Spain. This system provides three distinct riding modes—Race, Forest, and Wet—allowing riders to tailor power delivery to specific trail conditions via a handlebar switch.

Beyond the fuel injection, the 2026 engines now include a counter-rotating balance shaft designed to significantly reduce vibration, a common complaint with previous generations. The bikes also transition to a diaphragm clutch system, replacing traditional coil springs for a lighter and more precise pull. Suspension remains top-tier with 48mm KYB AOS forks and a fully adjustable KYB rear shock, ensuring that the MR 300i remains a serious contender in the hard off-road market.
