MR PRO 300i 2026
Spanish engineering to conquer the world
The new RIEJU MR PRO 300i MY26 takes Hard Enduro to another dimension. Light, agile and brutally reactive, it is the ideal companion for riders looking to push every challenge to the limit. Underneath its sharp looks beats a 300cc 2-stroke engine with TFI electronic injection, designed and built in Spain, offering precise, punchy and controlled power delivery without sacrificing the essence of the two-stroke.
The new MR PRO doesn't just roar with power: it thinks and adapts. Thanks to its three selectable power maps - Race, Forest and Wet - it responds with precision in any environment. The new diaphragm clutch, electronic exhaust valve and counter-rotating balance shaft ensure smoothness, control and superior stability on even the most technical trails.
Equipped with KYB forks with DLC anti-friction treatment, Renthal Fatbar handlebars, X-Trig Rocs seatpost, Excel tyres with Michelin Enduro Medium, Polisport handguards and a host of premium details, this PRO is pure elite. Light, sophisticated and fierce, it represents the essence of modern Enduro: GO HARD, OR GO HOME.
Features
New TFI injection engine
MADE IN SPAIN. Thanks to its new and advanced TFI injection system, it is able to perfectly emulate the sensations, response and feel of the 2-stroke carburettor engines, thanks to its innovative system of 2 Bosch Injectors differentiated for High and Low revolutions. All this results in an extraordinary instant and forceful response, combined with the smoothness and efficiency of modern fuel injection engines.
Three power maps
3 clearly differentiated Riding Modes as standard, to adapt the power curve to each terrain and riding style, optimising performance to the maximum: Race Mode (maximum power to feel like a real racer in the chrono), Forest Mode (control and power in equal parts to enjoy any terrain) Wet Mode (smooth and progressive delivery, ideal for low grip conditions).
Electronic exhaust valve
A modern electronic exhaust valve automatically manages its opening according to revs and throttle position, for instant and consistent performance at all times and in all conditions.
Balance shaft
Equipped with a counter-rotating Balance Shaft, it improves engine stability, minimises vibration and allows the engine to turn smoothly, taking the riding experience to another level.
Diaphragm clutch
More precision, greater control and extraordinary sensitivity. Lighter than traditional models, this clutch provides greater sensitivity and significantly reduces fatigue even in the most demanding conditions.
KYB Suspension
Surgical precision at every impact and outstanding stability on any surface, adaptable to any rider and riding style.
It features a 48 mm KYB Inverted Fork, equipped with AOS (Air-Oil Separated) System and Closed Cartridge with black anodised DLC antifriction treatment, and a KYB Monoshock fully adjustable in Preload, Rebound and Compression (differentiated in High and Low speed), anchored to a progressive linkage system.
EXCEL wheels
Durability, lightness and maximum grip. Measuring 90/90‘ on the front wheel and 140/80’ on the rear, these aluminium radial rims, equipped with Michelin Enduro tyres, guarantee impeccable stability and unrivalled traction.
Renthal FATBAR handlebar
Absolute control in every manoeuvre. Thanks to its design and variable diameter, this sturdy and stylish handlebar guarantees light-as-air steering and impeccable elasticity in every turn. You'll always be ready to take on any extreme challenge you set yourself.
