I’m not going to pretend I know which model BSA this is (though Tom says it could be a BSA M20), but it’s clearly old and the owner hasn’t bothered restoring it. Maybe because it gets ridden regularly? If so, I admire this owner’s resolve. Some might call it beat up, others would kill for the kind of patina this BSA has. The front suspension likely isn’t cut out for L.A.’s shoddy roads, and how much give do those tired springs under the seat provide over a pothole? And did you notice it also has a passenger seat and pegs? Brave soul, whoever rides back there…
