Yes, it is. I'm 49, and currently ride modern stuff (R1100RS, Bandit 1200, KLR) but over the years have met several long-time Indian riders, not all on Chiefs, some on Scouts, who have had the same bike for like 40 years! Sure, they've rebuilt the clutch and top end so many times they can't remember how many times. There is something to be said for familiarity with your motorcycle, especially if you're planning to keep it for a while, a long while. Also pass time sometimes with H-D riders who have had the same Panhead since 65 or whenever. I admire that in a person.
