[Ascalon]

I spend a lot of my time commutting trough the city and was getting concerned about sustained high temps, as in staying between 90 and 108c on my ST4s. The fan kicks in and out but sitting in heavy traffic, directly in the exhaust draft of a buss doesn't do anyone any good!

I looked into Water Wetter and decided against it. Instead, I went with Motul MoCool, which is formulated to do the same thing, but by a company that is more motorcycle focused. It is put in in a 5% solution to an existing system and I can report that same effects as the others here. It takes longer to get hot and when it does get hot, it cools quicker. That said, I still see occasional peaks that are pretty high. 118C flashed up for a second the other morning.

But I have the up rated Desmotimes fan on the way too, so that should help take care of the peaks.

So, I'd say, if you have any doubts on the Water Wetter solution go with the Motul stuff, it's recommended for bikes.
