2027 Rieju MR 300i: Racing, Pro, and Hard Enduro Split Three Ways

Hard-enduro shoppers who already like an injected 300 two-stroke just got a clearer menu. For 2027, Rieju keeps the Spanish-built MR 300i motor and its Race / Forest / Wet maps, then splits the bike into three factory versions: Racing, Pro, and Hard Enduro. Motorcycle Powersports News and Dirt Bike Magazine’s press package frame it as a trim-and-protection cycle - not a clean-sheet engine.

If you race club enduro or slow technical loops and want two-stroke torque without a carburetor, that matrix is the news. Central Powersports Distribution remains the U.S. importer in Dirt Bike’s coverage. This is still a dirt enduro platform - not a plated dual-sport tourer.

What’s shared across the range

Per the OEM sheet carried by MPN and Dirt Bike, every MY27 MR 300i gets a new LED headlight and redesigned front mask for low-light visibility, plus trim-specific graphics. The TFI 300i story stays the same: immediate response with three power maps you can actually use in Race, Forest, or Wet conditions.

MR 300i Racing

Racing is the lean enduro trim - compact and agile on paper. The published kit includes Racing 2027 graphics, EXCEL wheels with cast hubs and Mitas Terra Force tires, a Power Racing by OXA exhaust, Neken bar and grips, and Nissin brakes with Galfer discs.

MR 300i Pro

Pro steps into race-kit hardware: Pro 2027 graphics, a KYB fork with black anodized DLC treatment, red XTRIG triples, a Renthal Fatbar, Power Racing by OXA exhaust, EXCEL wheels with red machined hubs and Michelin Enduro tires, plus Nissin brakes with a floating Galfer front disc.

MR 300i Hard Enduro

Hard Enduro is the fully stacked trim for slow technical work. Engine-side changes in the press sheet include an inertia bushing, a Hard water-pump cover with a higher-flow impeller, and a specific spark plug aimed at low-rev drive. Cooling adds a dedicated expansion tank and a twin electric fan module.

Chassis and protection called out as standard on Hard (optional elsewhere) include a Hard-specific exhaust, short final-drive gearing with an AXP chain guide, EXCEL wheels with black machined hubs and Michelin Enduro tires, Nissin brakes with Galfer Wave discs (Hard-specific rear), an AXP Enduro skid plate, swingarm protector, front and rear disc guards, machined aluminum bar protectors, offset stainless footpegs, tow straps, black XTRIG triples, simplified wiring with a twin start button, a red Hard seat, and Hard 2027 graphics.

Price and who should care

September 4-5 coverage republishing the MY27 materials still does not list U.S. MSRP for Racing, Pro, or Hard. Earlier MY26 U.S. reporting published Racing and Pro stickers for that year - useful history, not a MY27 price. Confirm current dealer numbers with Central Powersports or an authorized Rieju shop before you budget a crate.

If you already like the MR 300i map set, MY27 is about picking a factory trim: Racing for a leaner woods bike, Pro for KYB / XTRIG race bits, Hard Enduro if you want twin fans, short gearing, and the AXP protection stack without building it yourself. Ask your dealer which trim is actually landing in U.S. crates first - and budget chest protection and skid-plate service for rockier loops.
