A good look here:

2025 MR300i

It appears to me to be the same bike we know - frame, plastics, etc. - with the new engine. That's not a bad thing as far as I am concerned, I like the existing platform.

Too bad the photographer doesn't know that the bike has a left side

Great find! It looks like the engine is made in Spain which is great! I was beginning to get scared it was a made in China engine since they are using Chinese motors in the larger bikes. BTW, Moto.it is a great resource if you want to look at cool vintage bikes. Take a look at all the used vintage bikes for sale under the "Epoca" tab on their website!

Looks like Mark updated FB and Instagram with some more info and pictures. Below I copied in the text. Notice that he says potentially larger than 300cc motor in near future and possible carb version in 2026.

“TFI”. Throttle body Fuel Injection. Premix, no oil injection.

Counterbalanced crank

Electronic Powervalve

New diaphragm clutch for better performance.

Does it have kickstart? NO, not possible, sorry but it can be bump or push started when battery isn’t effective.

Is there a carbureted version? Not currently but for 2026, it is intended to offer both options.

It will come in 300 Pro and 300 Race version with the 250 coming after.

The current Ranger 300 will remain with existing engine platform until 2026.

The 200 (other than some Six Days models coming) will be going away as this new platform is designed for 250 and bigger (potential larger displacement for 2026).

MSRP for the USA will be announced to dealers on Nov 15th.

Rieju USA will have our order period from Nov 15th to Dec 1st and each dealership will have an opportunity to order a “demo” or hire their own “sponsored rider”!

We will see the bikes in the USA in March/April.

I vote for a 500cc 2 stroke!

In the spirit of the Rieju slogan "Go hard or go home", they should "go big or go home": Make it a full 700cc to be larger than the Zabel or Maico 700 (685cc actual size)!

Wow - unique throttle body. Idle throttle plate opening / air bypass on the bottom. I like it.

Looks like the system might use both crankcase pressure and "manifold" pressure sensors for injection volume (a port on the right side between reed valves and cylinder, and port on right side by reed valves into crankcase).

I might have to travel to the dealer in a few months!
