I will put this out there. Applying for a title, when the DMV wants to know what year bike I have, I always tend to put the mfr date on the tag. Mine is 10/70 so I said it's a 1970 even though I had my doubts that it probably didn't hit the dealer floor till 1971.
What would you guys do?
If it didn't hit the dealer floor until 1975, it would still be a K0. If they didn't sell it, or title it until 1979, it would still be a K0. If you bought it in 1979, and titled it, would you call it a 1979 CT70?
Lol...I don't know why I always want to fight this battle.
I guess if you prefer to call that 1969 K1 Z50 a 1970 Z50 that is cool with me.
But if you tell ME that you have a 1970 Z50, I will ALWAYS ask, "Is it a K1 or a K2."
I prefer my 1970 Z50's to have a foot brake, and a oval badge on the tank.
And I prefer my 1971 CT70s to have the good front shocks.
