The 2026 Rieju MR Pro 300i is Spanish hard-enduro engineering at the edge of what a 2-stroke can do — light, agile, and brutally reactive, built for riders who push every challenge to the limit. The 298cc TFI fuel-injected 2-stroke uses two Bosch injectors (one tuned for high revs, one for low) to deliver carburetor-feel snap with EFI smoothness. Three selectable power maps (Race, Forest, Wet) adapt the bike to terrain, and a new electronic exhaust valve plus counter-rotating balance shaft mean it stays composed when the trail goes vertical. Premium-everything spec list: KYB 48mm inverted closed-cartridge forks with DLC anti-friction treatment, KYB monoshock with progressive linkage, Renthal Fatbar handlebars, Excel rims wrapped in Michelin Enduro Medium tires, and Nissin brakes. Go hard or go home.

The 2026 Rieju MR Racing 300i is the no-excuses, no-frills Spanish hard-enduro 2-stroke for riders who want to set the pace, not chase it. Same 298cc TFI fuel-injected engine as the MR Pro 300i — with two Bosch injectors (high/low rev) feeding instant carbureted-feel response — tuned in Racing spec for riders who care about results, not badges. Three power maps (Race, Forest, Wet) adapt to terrain, the electronic exhaust valve and counter-rotating balance shaft keep the engine composed, and the KYB suspension package delivers surgical precision through whatever the trail throws at it. Black anodized Excel wheels, Mitas Terraforce tires, Neken handlebars, lithium battery, and Power Racing by Oxa exhaust round out a package that’s ready to roar from the first second. Compact, agile, brutally efficient.
