What these guys are trying to nicely tell you is, these bikes are not a Harley or BMW. These bike are like a fine woman. They like to be ridden hard, but you better spend some time with them afterwards. Not put her up wet and sloppy, and go in the house to sleep.
I've ridden in the rain many times, with no problem, but the clean up afterwards takes hours. If your going to treat her like a two bit whore, I'm going to say these are not your type of bike. Move on.
I tear down several bikes a year, that guys have bought from guys that treated their Dogs like crap. Mechanically their in good shape, they just look like a girl that smokes 3 packs of cigarettes a day for the last 20 years.
Don't buy a Dog, if your going to treat her like that. These are the finest custom- production bikes out there, and need to be treated with respect!
