MR 300i RACING 2027
HARD OFF ROAD, REAL EMOTION.
The new MR 300i RACING MY27 is an Enduro machine designed to perform at its best on the toughest terrains. It inherits RIEJU's offroad legacy with the 300cc 2-stroke engine featuring TFI electronic injection, developed to offer immediate response and total torque control.
It features three power maps that adapt to each terrain and riding style. Its chassis provides solidity and agility, while the high-end KYB suspension set ensures impeccable traction and absorption.
It is equipped with EXCEL rims, Mitas Terraforce tires, Power Racing exhaust by OXA, Neken handlebars and grips, and a lithium battery. For 2027, it incorporates a new Racing decoration, the new LED headlight from the MR range, and other improvements aimed at maintaining performance in the most demanding moments.
Compact, agile, and efficient, it is the natural choice for those who live Enduro without limits. MR Racing 300i. For those who don't look for excuses. Just real emotions.
Features
New 2027 aesthetics and LED headlight
Debut the new Racing 2027 design, along with the new LED headlight that refreshes the look of the entire MR range and enhances visibility during the most challenging hours. Additional improvements have been made to maintain performance during the most demanding moments.
New TFI injection engine
MADE IN SPAIN. Thanks to its novel and advanced TFI injection system, it is capable of perfectly emulating the feel, response, and touch of carbureted 2T engines, thanks to its innovative system of 2 Bosch Injectors differentiated for High and Low revolutions. All of this results in an extraordinary immediacy and forcefulness of response, combined with the smoothness and efficiency typical of modern Injection engines.
Three power maps
Comes standard with 3 clearly differentiated Riding Modes, to adapt the power curve to each terrain and riding style: Race Mode (maximum power to push yourself in the time trial), Forest Mode (control and power in equal parts to enjoy any terrain), and Wet Mode (smooth and progressive delivery, ideal for low-grip conditions).
Electronic exhaust valve and balance shaft
The electronic exhaust valve automatically manages its opening based on the revolutions and throttle position, to always provide instant and consistent performance. Added to this is a Counter-Rotating Balance Shaft that enhances engine stability, minimizes vibrations, and allows it to run more smoothly, taking the riding experience to another level.
Power Racing exhaust by OXA and diaphragm clutch
The Power Racing by OXA exhaust brings out all the character of the TFI engine, while the diaphragm clutch—lighter than traditional models—provides more precision, greater control, and extraordinary sensitivity, significantly reducing fatigue even in the most demanding conditions.
KYB Suspension
Surgical precision in every impact and outstanding stability on any surface. 48 mm KYB inverted fork with AOS (Air-Oil Separated) system and closed cartridge, along with a fully adjustable KYB monoshock in Preload, Rebound, and Compression (differentiated in High and Low speed), anchored to a progressive linkage system.
EXCEL rims and Mitas Terra Force tires
Durability, lightness, and maximum grip. The EXCEL aluminum radial rims with cast hubs, combined with Mitas Terra Force tires, offer excellent stability, great traction capability, and reliable performance on all types of terrain.
NISSIN brakes and GALFER discs
Power, precision, and control in any situation. The combination of NISSIN calipers and pumps, paired with 260 mm front and 220 mm rear GALFER discs, provides powerful, progressive, and perfectly modulable braking, with a precise and consistent feel even during demanding riding.
