Frankly, I think liquid cooling is the way to go anyway...
I said 10 years ago after riding my first V-Rod that Harley should punch it up to 1600 or 1800ccs
and put it in a bagger but no one listened!
Now looks like Indian is listening...
NO DOUBT water cooled is better. I came from a water cooled bike to my streetglide and as soon as the weather got above 85 degrees, i noticed how damn hot my leg gets. Gota keep these things rollin or you bake. But there is no sound like that of the Harley. I got hooked.
