Well, the AMCA says over 35 years is antique. I think that’s BS. Honda’s aren’t antiques.
And now that I think if it there isn’t any year parameters for classic. Classic should be something that has some special deal to it. Say a classic Brit bike . 60’s triumphs etc.
a classic bobber in traditional sense .
Harley softails could be classic despite the year.
Perhaps recent RE’s could be considered classic.
Classic UJMs etc.
but just because a bike is old doesn’t make it a classic.
Vintage. ? Pretty much anything that’s not an antique. The 1927 cut off mentioned works for me.
100 yo is antique furniture and stuff like that.
Not sure it applies to bikes but given a couple of more years it will .
Inflation belongs in your tires.
Not in your grocery bill.
