Yeah some of them are pretty hot looking bikes....I was told the air cooled HD's were HOT.
Sorry, thought it was a good answer.
Yes some are hot blooded, but a few modifications like oil cooler and tuner helps. However on the open road and the air flowing past that big motor, running at the unmentionable speed, you really do not feel the heat, it's mostly in town and stop and go traffic.
But there is a Harley that is water cooled: the VRod, before marketing was ran through the mills and pushed hard during tests in the desert and passed with flying colors. my :tc1:
I own both and love both, the rides are different but they are different bikes.
