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.
