Spanish manufacturer Rieju has taken a bold step forward in the enduro biking world by unveiling its fuel-injected two-stroke models for 2026. The MR300i Pro and Racing versions are set to redefine performance standards with their innovative features. Developed over several years, these bikes boast an advanced engine, enhanced suspension, and cutting-edge technology that promises to deliver an unmatched riding experience.

The new MR300i is not just about power; it's about precision and adaptability. With three distinct engine maps and a diaphragm clutch system, the bike caters to various riding conditions and preferences. Additionally, its lightweight design and premium components make it a standout choice for enthusiasts looking for both performance and value.

Revolutionary Engine Technology Powers Ahead

The heart of the MR300i lies in its meticulously engineered 300cc two-stroke single-cylinder engine. Equipped with throttle body fuel injection, this Spanish-made marvel offers precise and punchy power delivery. Bosch injectors ensure optimal fuel consumption while maintaining the responsiveness traditionally associated with carbureted models. Furthermore, the inclusion of three customizable power modes—Race, Forest, and Wet—allows riders to tailor performance according to varying terrains.

This technological leap signifies a significant investment by Rieju, who have worked tirelessly to perfect the fuel injection system. Alfredo Gomez, instrumental in developing KTM's fuel-injected engines, was a key figure in this project. His expertise ensured that the MR300i delivers unparalleled performance without compromising on environmental standards. By integrating a counter-balance shaft, vibrations are minimized, enhancing stability and rider confidence. These advancements collectively create a machine that is as agile as it is powerful, making it ideal for those seeking the ultimate Hard Enduro experience.

Premium Features Elevate Riding Experience

Beyond its engine, the MR300i excels through an array of high-quality components designed to elevate rider satisfaction. A diaphragm clutch replaces the traditional coil spring system, providing smoother modulation and improved feel. This feature, exclusive to the Pro model, complements the KYB suspension setup, which includes 48mm inverted forks with AOS technology and a fully adjustable monoshock rear suspension. Such specifications guarantee superior handling across diverse trails.

In addition to its mechanical prowess, the MR300i boasts an impressive list of standard equipment. From black anodized Excel rims and Mitas Terra Force tires to Neken handlebars and OXA exhaust systems, every detail has been carefully considered. The Pro variant further enhances this offering with additional luxury items like Renthal Fatbar handlebars, Michelin Enduro Medium tires, and a non-slip two-tone seat. Weighing just over 100kg dry, equipped with a generous 9.8-liter fuel tank, and featuring three rider modes, the MR300i represents exceptional value within the enduro market. While pricing details remain undisclosed at present, Rieju continues its tradition of delivering top-tier performance at competitive prices.
