Re: how comfortable is your bike?
Build your own seat and then add padding, padding and a little more padding. Standard bicycle seats were never meant for the kind of riding we typically do on our motorized bikes. We sit more than stand on the pedals so we need something more like motorcycles have.
I've built a couple and I use what the upholstery guys call "motorcycle foam". It is high density foam rubber, much firmer than what is used for pillows and sofa cushions.
Leave those skinny, hard saddles for Lance Armstrong and the rest of the the roadies. Build yourself something that won't bury itself in your backside after ten miles.
