May 22, 20215 yr Hi I have just bought an ossa 250 mar . I have a frame number beginning B 223 and wondered if any one can date the bike for me . Many thanks
May 24, 20215 yr Using the number is not that easy. If you post a photo showing the head and cylinder finning and the type of connection for the carby you will probably get an ID on the cylinder and head. The ID number for the bottom end of the motor is usually on one of the front engine mounting lugs.
May 24, 20215 yr Hi PH1, I have just bought one also and found this website useful when checking my serials, OSSA MODELS REFERENCE LIST (2y.net) http://ossa.2y.net/ossa/reference/ossaref.html Hopefully the links work, if not copy and paste the second one into your browser, Regards
