Have been wanting one of these ever since I saw one. Only made for 1 year... it's a 1988 Radio Flyer MB52. Yes the same company that made the wagons and the sleds. Still in business today. I actually called the company and a sales rep gave me info on the mini-bike. They made them originally from 1938 to 1942 then remade for 1 year as a 50th anniversary. Pics are taken with a spray paint can just to give you an idea of how freakin' tiny this thing is.
