The Spanish off-road school pulls no punches and raises the bar. Rieju completely revives its diamond in the rough in the specialized segment by presenting the new Rieju MR 2027 range. Three distinct interpretations of the same enduro passion, all based on the proven 300 cc two-stroke engine with TFI electronic injection designed and built on Iberian soil.
From the entry-level Racing version to the monstrous Hard Enduro, the family updates its aesthetics with a new LED front mask and technical packages designed for those who seek zero compromises in the mud.
The Common Core: TFI Electronics and KYB Suspension
Regardless of the chosen version, the mechanical base shares top-tier technical solutions aimed at total control of the vehicle:
The TFI System: Electronic injection manages three power delivery maps (Race, Forest, and Wet) designed to calibrate throttle response and torque based on terrain hazards.
Mechanical Stability: Clean riding is supported by a diaphragm clutch, an electronic exhaust valve, and a precious counterbalancer shaft that cuts down vibrations.
Suspension Department: All variants rely on high-end KYB hydraulic packages, paired with a perimeter steel frame that keeps the proverbial agility of the MR lineage intact.
The Three Souls of the 2027 Range
1. Rieju MR 300i Racing (From €9,499)
The gateway to the Spanish manufacturer's race world. Compact, sharp, and designed for those who want substance without frills. It features Excel rims with cast hubs, Mitas Terra Force tires, a Power Racing by OXA exhaust system, a Neken handlebar, and Nissin brakes paired with Galfer discs.
2. Rieju MR 300i Pro (From €10,599)
The next step for those looking for technical refinement. The KYB fork adopts an anti-friction DLC treatment with black anodized stanchions, paired with exquisite red-anodized Xtrig triple clamps. The package is completed by a Renthal Fatbar handlebar, Excel rims with machined-from-solid hubs, Michelin Enduro tires, and a floating front disc.
3. Rieju MR 300i Hard Enduro (From €11,199)
The undisputed queen of mule tracks and extreme passages. The engine receives dedicated modifications aimed at low-end traction (inertia weight/casquillo de inercia, oversized water pump cover, and specific thermal components). The chassis boasts enhanced cooling with a dual electric fan, a shortened final transmission with an AXP chain guide, and a true factory-fitted protective shield: an AXP skid plate, disc guards, swingarm guards, billet aluminum handguards, and grab straps to pull yourself out of trouble.
Who It Is Suitable For
Two-stroke purists looking for a full displacement (300 cc) capable of combining the bottom-end grunt of modern engines with the reactivity of TFI injection.
Amateur or competitive enduro riders who want a bike ready to race out-of-the-box, choosing the level of chassis refinement based on their budget.
Anyone who regularly tackles extreme terrain and looks in the Hard Enduro version for a fully armed bike right out of the box without needing to hit the aftermarket.
Who It Is NOT Suitable For
Total beginners or anyone looking for a light touring or street-commuting bike: these are registered, rowdy, and specialized competition machines.
Those who prefer the linearity and lower maintenance of a modern four-stroke engine.
Pros and Strengths
Extremely articulated and targeted range, capable of covering every real need of the enduro rider.
Top-tier KYB suspension department across all versions.
Impressive standard equipment on the Hard Enduro variant (protections and fans included).
Decisively aggressive quality-price ratio compared to Central European and Japanese giants.
Cons and Potential Issues
Electronic injection and fluid management require careful maintenance and constant cleaning in the most extreme muddy contexts.
The Hard Enduro version, despite being ready for anything, has a heavy and demanding presence for less physically fit riders.
The Crazywheels.it Perspective
Rieju continues to defend the European fortress of hard-core off-roading tooth and nail. The move to revamp the MR range with three such targeted levels shows that in Figueres they know perfectly well what the true enduro rider wants: substance, noble components (KYB, Excel, Nissin, Oxa), and zero compromises. The Hard Enduro version is a true mud-ready prototype straight out of the factory. If they keep maintaining such aggressive entry price lists, the competition would do well to start worrying.
