To cool means remove heat energy water being over 3000% more efficient at doing that job than air. How is your experience . I've entered the efficient age of heat removal. Water is controllable and more even than any air cooled scooter IV put in tween my legs. Appears that manufacture are offering this option more as baggers get bigger . no itchy crotch coolers. Or bitching at light that my jewels are frying on a 95 degree day. Wonder if day of air cooled scooters are numbered. In defence those air cooled jugs are sexy. And Lord we all love jugs. Just a thought. !!!! Do a burn out leave your mark!!!!!!
