In my entire 65 years of life, outa all my toys, bikes, cars, etc., my motorized bikes have given me the most satisfaction.
Why? Because it gets me to where I wanna go on a regular basis. I built it and made my own improvements. It keeps up with city traffic. If it cost $100/gallon(not $3.89), I'd STILL ride my MB.
And then there's "that look".
