Back in the Day "Where do you live and when won't you be home?"
When Sportsters were the thing, for every K model made a Sportster was stolen, then you would bust the cases of the K, send them into HD and get a new set of Sportster cases, swap the parts and a legal bike emerges. When they were caught or like this thing, defaced, the DMV would issue you a new number and pop rivet it onto the case and frame. If you got one of these all it needed to do was pass stolen bike records and a lien sale and it was yours. Really too bad, I'll bet that SP is full of stuff. I want an SP!........ or a Quality.
