1975 Rupp RST100

In America, Small Displacement by AbhiLeave a Comment

Founded in 1959, Rupp Manufacturing started out as a kart manufacturer in Mansfeld, Ohio. Within 10 years, they had grown to a 400-employee shop pumping out mini-bikes, go-karts, snowmobiles, and what some people consider to be the first “4 wheeler” – the Rupp Go Joe. Here’s one of their rare mini bikes – the RST 100.

This example isn’t perfect but these bikes are very hard to find nowadays. Expect to replace the carb needle and the seat, then adjust the clutch and buy an intake. Find this RST 100 (VIN: 5605003) for sale in Rockford, Michigan with bidding up to $405 and the reserve not yet met
