Radiator Coolant, any better than others?

[ol' boy]

Thanks Tiny

I actually watched a YouTube of guy that run Evens in his YZ250F
Engines temps were off the charts!!!! with the same riding

Might be good for engines in storage, but perhaps not so for high performance engines on the limits

If you can get through this guy's incessant babbling, you find a few nuggets on the water-less thing...there are 2 or 3 tortuous vids to get through, he is on the right track though. He focuses on the heat absorbing and dissipating properties of (in this case) liquids. If you have a cooling system with a big (or modified) capacity you should be fine (although in theory the flow rate should be looked at as well), but many a motorcycle race teams (most bikes have borderline systems to keep weight down) have tried and gone back to a water mix.
