Since Evans is waterless it can't cool as well as stock coolant, but it also doesn't boil for the same reason.

The stock cooling system is overbuilt and reliable, so Evans won't cool your bike better but you probably won't notice the difference since the cooling system is always overbuilt. The only advantage is it won't boil over ( until like 350° or something), so there's that if suits your needs.

Yeah, it has a higher boiling point than 50/50 antifreeze, but that's marketing fluff wrt production streetbikes, as 50/50 in a pressurized cooling system boils at like 260-270, with the coolant temp warning light coming on before that, indicating a malfunction. So that 80-90 degrees of 'boilover' protection is pretty much useless, as you were supposed to shut the engine off well before you got to that point.

Edit: Just checked their Web site, years ago they used to basically sell like one product which was essentially like 95% propylene glycol packaged different ways, but now they have several chemically different coolants. There's still their original PG-based product, but they also have an EG-based product, as well as their 'TrackWater' which looks just to be water + surfactants + corrosion inhibitors and in terms of cooling performance should be the best, as long as you don't care about freeze protection. Red Line also sells something similar.

 

Pure water has the most heat carrying capacity, but promotes corrosion and tends to break shit when it freezes.
50/50 antifreeze works just fine on these bikes in 90F weather. It will get hot in traffic, but that's unavoidable.

For a streetbike with a pressurized cooling system designed for 50/50 antifreeze, Evan's is marketing BS and a ripoff. Like selling you a 300mph rated tire for $1000.

 

For street bikes, I agree it's a waste of money and there's no cooling performance to gain. There is one niche use where it can come in handy, and that's racing dirt bikes in the woods. Since the boiling point is so high, if you get a pinhole in a hose or radiator, it'll leak out slowly vs blasting out under steam pressure. You can finish a 2hr hate scramble rather than stopping instantly for repairs. I've seen that done before.

Even then, you don't expensive coolant to do that. Just get the normal $15/gallon stuff and run it straight without cutting it with water.

 

It also seems to be popular among the vintage car crowd too. I guess they like the 'waterless' part of it because their cars only get driven 20 miles a year to car shows and then mothballed. No water, no corrosion! Never mind that regular 50/50 you can get at Pep Boys has corrosion inhibitors.

If you market it, they will come.

Damn, that's just shameless 😂
