The BSA B50 MX is a four stroke 500cc single-cylinder motorcycle, which was produced between 1971 and 1973. Only a handful were sold in the United States. We bought this motorcycle in rough condition and Ziggy restored it to its former glory. As we combed through the parts and paperwork, we found a receipt from when the bike was originally sold by Ted Evans shop in Los Angeles in 1972. The new buyer was his son Eddy, who wanted a memento from the shop’s heyday.
