BSA ? Triumph
Orange of course
Original 1969 BSA returned from USA and restored to full X75 Spec, too too pretty to ride all the time but lovely to look at. they were all designed around the BSA and when they went burst the remainder got badged Triumph ! look closely and even the big rear sprocket has BSA stamping on it.
