..as I don't like to spread rumors...but here's a rumor I heard. While at Destination Daytona today, I was talking to a salesman who told me he heard that Harley had gotten a patent for their new water cooled system. Say's it won't be fielded for a couple of years but Harley has a system planned. According to him the radiator will be on the down tubes above the regulator and it will not only cool the engine but will also have water jackets around the head pipes to keep down the heat on them. He was telling methis as we looked at brand new 2012 bikes..not a lot new that I could tell. Anyway, I haven't done any research on this so take it for what it is. thought it was interesting.
