EPA regs have pretty much forced HD to go water cooled. Personally, I prefer water/air cooling to just air. Traded in a Street Glide for a Goldwing because I was spending lots of time in traffic. 100°+ on a HD in Texas sitting in traffic is no fun. Liquid cooling will make the engines last longer from what I understand.
I hear they’re starting to build Harleys in China. Probably better quality...
