Do you have a pre-1982 "Sporty" bike?
Could you afford, or already own, a modern motorbike anyways?
Find little appreciation from the modern bike crowd around you?
Looking for someone to talk tech with?
Read (and understood) "Zen and the Art of Motorcycle Maintenance"?
If you said yes to most of the above, you're like me, and we should get a Classics sub-group going.
Mine is a KZ650, let's have a coffee and tell them youngsters to slow down!
