Unbelievable price for that AMF. I have this one that runs like new with original tires (they use a raised rib on center for friction drive to run on) and can't reach 20mph on level ground, let alone climb a hill with a 170lb rider. The engine is kind of a novel design but way underpowered. I wouldn't take 5 of them for any of my Kinetic TFRs, Tomos, or Trac mopeds, let alone Honda Cubs or Ct's!!! Goes to prove fools and their money can be parted. (Especially in a Auction setting)
