1989.
Not aware of a month ? 1989 on the comp plate is my interpretation, never tested it, can do a bit of digging.
It is the first month of 89. So I guess you were spot on.
Gidday Guys ,
Curious about this thread … does the cut off year change every few years … I bought a 76 Super Glide back in the mid to late 80 `s from U.S. Cycles up here in Qld .
At the time it was unregistered and had no Compliance Plate but U.S Cycles got it registered and told me the cut off date was Mid 76 to late 76 and mine was a early 76 build and was how they got it registered .
Not sure if they had a friend in the Rego Dept or did a swifty but I did sell it sometime later and had no issue changing rego ownership .
Thanks for any reply`s
Tim .
