Is it a high mileage bike, or not?

90,000 miles on a 1986 Kawasaki Concours

A few days ago my Concours (aka the Connie or Miss Swail) rolled over 90,000 miles.  This is the farthest I've personally taken a motorcycle and actually higher than over half the cars and trucks I've owned.  So I'm pretty confident this will be my first 100K motorcycle and I hope to get another picture like this one in 10,000 miles. 

But on yesterday's Christmas Eve ride, I started thinking about it.  Since the bike is a 1986, it's almost 28 years old, depending on construction date and motorcycle model year release dates.  Dividing 90,000 by 28 leads to just over 3,000 miles a year (hey, this is a motorcycle riding and motorcycle maintenance blog, not Khan Academy!).  I know I haven't ridden this bike exclusively while I've owned it, and it sat for two of those years, but 3,000 miles a year is nothing.  Especially here in Southern California where we ride year 'round (hmm, OK 364 per Aerostitch!) that's really only a few months of riding.

So I'm thinking the bike is "old" and some of the issues are caused by age (gaskets/seals drying out, lines soft, seat wearing out) more than the mileage.  On the Concours forum there are both C10s and now C14s with well over 100,000 miles and I think a few C10s have gone over 200K!  I'm looking to get at least to 100K and then evaluate picking up a newer C10 with the upgraded front end but the same reliable power plant.

Merry Christmas to all!
