2026 RIEJU MR300 PRO

Rieju first to launch 2026 enduro models – fuel-injected two-strokes finally land, beating every other manufacturer to the punch by releasing their long-awaited fuel-injected two-strokes, the MR300i Pro and Racing versions.

It feels like we’ve been talking about this updated bike for some time now, with Enduro21 stories going back over a year. That’s mainly because the Spanish manufacturer has been developing the bike very much in public – and at the races.

It’s a risky strategy when things don’t quite go to plan, but it also builds anticipation. For a manufacturer with a presence in just about every major race championship, you could argue that all publicity is good publicity.

The result is a machine with some significant updates. Most notably, the in-house developed, throttle body fuel-injected 300cc two-stroke engine. But there’s more to note: a diaphragm clutch, three engine maps, counter-balancer shaft, 48mm KYB AOS forks and KYB rear shock. The 2026 Rieju MR300i – in both Racing and Pro editions – is not short on spec and should grab your attention if you’re in the market for a new enduro bike.

irst class R&D

Developed over several years now with Alfredo Gomez notably taking the fuel injected bike to selected Hard Enduro World Championship races as part of the programme, Rieju’s new bike has showcased itself handsomely in the hands of Dominik Olszowy.

The Polish rider, who bases himself near the Rieju HQ in Figueres, near Girona in Northern Spain, has been a factory rider for a couple of seasons and has also been part of the R&D team developing this bike in that time. It’s a bike which he clearly gels with and ticked off SuperEnduro World Championship race wins and an EnduroGP Super Test fastest time just last weekend in Portugal.

The new Hard Enduro range (not just for hard enduro you understand, although it could be, but hard as in tough, we assume) consists of two models at present: Racing and Pro editions. So, no 250 model at present and only 2T bikes for enduro but who’s complaining?
