I had an SL70 when I was a young teenager. Eventually got my motorcycle license. Never enjoyed riding big bikes though. Recently I purchased a nice reconditioned 1971 SL70 KO. Not sure what the KO stands for but it has 117 cc engine.´ Anyway the registry doesn´t want to register it without the registration from the previous owner of which there is not one because the bike was really built from scratch. And they want the bill o f sale from the person from whom I purchased it from. He doesn´t have one. He bought the frame at a swap meet and built it from that. It´s beautiful but unregistered. Anyone have the same problem or a solution?
