I have an update on the sting-ray bikes , both were from 1964 they were like one month apart on production date , these bikes had a very cool license metal plate ( Detroit ) registration with one digit apart when they were registered , i would like to thank everyone who helped me with the I.D. of these and a somewhat worth of were to start taking offers , I ended up putting them in my own silent auction at a recent bike show were basically highest bid takes both & the results were stunning . I mean unbelievable the winner was a collertor of early sting ray's from model years 63-64-65's he said they will go into his collection for years to come .
