The Shop
Are there still such a thing as moto dads?
Then yes, I'd say all the bikes in the 250 A Mod and 250 B Mod classes have one. You need it to win, right?
Several top teams were using them in SX and with the temps at LL it wouldn’t surprise me if lots were using it.
EDIT: I was also going to say that it's a logical extension to your product line, Lumpy.
Best way to get more cooling with factory reliability is to use a larger impeller mechanically driven as per standard to circulate the coolant faster. This is what factory teams use.
If your 250 has much higher compression and is being operated higher in the rpm band then running hot is a reliability issue so a better cooling maintains the power gains.
If it was just about cooling they would be adding oil coolers and/or radiator fans.
Pit Row
For the group: electrical water pumps also help cooling because they spin at peak RPM at all times, thus flowing more water volume through the radiator. Don't forget that even pros are only wide open some of the time.
Have been looking in to put it on a 125, but would be interesting to see if it’s worth it first.

I do know that the 2017-2020 CRF450R Supercooler may bolt on a 2021-2022 CRF450R but Boyesen does not offer one for the newer designed CRF. Doing that requires a much longer hose than what the 2021-2022 actually use.
