Hi - I have a 21 Street Glide with the Touring Pack. I almost always ride with a passenger.  My girl and I are average height and weight.  The H-D shocks ride hard... WAY harder than my previous 18 Road King.  We hit bumps hard. I don't want to waste money changing the suspension if what I really need is a different bike. Is it worth a try? Also, I like the current seat height.   Advice?
