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.
