The water is entering on the ex side of the cylinder. This is a very interesting new cylinder design. Thank You ESR for your continued investments and hard work into the 250r.

Very cool.  It is also available for up to +6 stroke.  81 x 78 sounds like an awesome set up.

I read about the reversed coolant flow just the other day. Really cool stuff.

If I could just get rid of about 9 other hobbies I would have one of these jugs already lol.

Carlen Gardner got 2nd overall at the world 2 stroke championships on a ESR CEO PV yz250.
He went 3-1 winning moto 2 for 2nd overall.
The hills and ruff track of Glen Helen along with this field of riders and equipment were a good test of the ESR CEO.
I read or heard somewhere that he lost his rear brakes while in 2nd in moto 1 so this was a close shot at an overall run but 2nd is still a great result at this event.

I don't personally own one, nor have I piloted an R with one. I did however ride with Eddie Sanders himself at the 2019 Winchester dunes meet.  Eddie had a 391 coe that flat out ripped.  It seemed like it had more power all around then my regular esr 391 cylinder.
