Billy: That "stupid exhaust" is actually the original factory exhaust system on the BSA B50MX. It's admittedly, a stupid system, an extra 25 pounds of chromed steel on a lightweight racing machine, and I have no idea what the "geniuses" at BSA were thinking while their whole empire was sinking in 1973. Maybe it had to comply with some noise regulations in the USA? Anyway, probably nobody raced their BSA B50MX with that double-megaphone system, and took them off. Then they got lost, discarded, etc. So the few with the original "stupid" exhaust are extremely rare and the exhaust system itself is worth $1000!
beautiful machine,thanks for sharing
