So what I've found out talking to several suppliers is most of them just use a bunch of terms associated with their products in each ad. I asked specifically about the water cooled version because it had a few photos of it and the air cooled version. He said they sell both and that when I order and tell them what options you want and they'll adjust the quote. So the bike was about 150 more for the water cooling. But It looked like a more stout engine and most Chinese resellers I've seen Around my area and on
Amazon only sold the air cooled ones.
