MR 300i PRO 2027

SPANISH ENGINEERING
TO CONQUER THE WORLD

The new RIEJU MR PRO 300i MY27 takes Enduro to the next level. Light, agile, and responsive, it is the ideal companion for riders looking to push every challenge to the limit. Beneath its sharp aesthetics beats a 300cc 2-stroke engine with TFI electronic injection, designed and manufactured in Spain, delivering precise, powerful, and controlled power without losing the essence of two-strokes.

Its three selectable power maps —Race, Forest, and Wet— allow it to respond precisely in any environment. The diaphragm clutch, electronic exhaust valve, and counter-rotating balance shaft ensure smoothness, control, and superior stability even on the most technical trails.

Equipped with KYB fork with DLC anti-friction treatment, Renthal Fatbar handlebar, red X-Trig Rocs triple clamps, EXCEL rims with red machined hub, Michelin Enduro tires, Polisport handguards, and a host of premium details. For 2027, it debuts its own decoration, a new LED headlight, and other improvements aimed at maintaining performance in the most demanding moments.

Light, sophisticated, and fierce, it represents the essence of modern Enduro:
GO HARD, OR GO HOME.

MODEL HIGHLIGHTS

New PRO 2027 graphics and new LED headlight, along with other improvements aimed at maintaining performance in the most demanding moments.

New 2027 aesthetics and LED headlight

MADE IN SPAIN. The same heart that has redefined the modern 2T: TFI injection system with 2 differentiated Bosch Injectors for High and Low revolutions, capable of perfectly emulating the sensations, response, and feel of carbureted 2T engines, with the smoothness and efficiency typical of a current injection engine.

NEW TFI INJECTION ENGINE

Three standard Riding Modes —Race, Forest, and Wet— to adapt the power curve to each terrain and riding style. The electronic exhaust valve automatically manages its opening according to the RPM and throttle position, ensuring instant and consistent performance in any circumstance

THREE POWER MAPS & ELECTRONIC EXHAUST VALVE

The plus that makes the difference. The 48 mm KYB inverted fork with AOS system and closed cartridge in the PRO features black anodized DLC anti-friction treatment: less friction, smoother sliding, and a finer response in the first few millimeters of travel, precisely where precision riding is crucial.

Rigidity, precision, and an extra touch of exclusivity. The red XTRIG triple clamps are one of the hallmarks of the PRO: they enhance the stability of the front end, refine the feel of the fork, and elevate the bike's finish level.

The Power Racing by OXA exhaust brings out the full character of the TFI engine, while the diaphragm clutch—lighter than traditional models—offers more precision, greater control, and extraordinary sensitivity, significantly reducing fatigue even in the most demanding conditions.

EXCEL aluminum radial rims with red machined hub, exclusive to the PRO version. A lightweight and durable set that provides greater driving precision and an unmistakable racing aesthetic, equipped with Michelin Enduro tires to maximize grip and extract every ounce of traction.

Power, precision, and control in any situation. The NISSIN calipers and master cylinders are paired with a 260 mm floating GALFER disc at the front, enhancing adaptability during intense braking and maintaining a more consistent feel even at high temperatures, and a 220 mm GALFER disc at the rear for a progressive and perfectly controllable response.
