I found one on craiglist a couple years ago for $100. It gets ridden everytime we go up.
Beats buying a 6K ATV to ride up and down our 2 mile road like my neighbors do.
Needs gas about once a year thing must get 200 mpg.
I had a 69 Honda 50 when I was a kid. boy did we ride that thing hard!! Had a hardtail rearend and about a whopping 3/4" front suspension. The thing was indestructible and rode it all the way up to about 16 as just a little playbike then. Minibikes were and are awesome for kids!
