And, just as important, don't forget to change out your blinker fluid at the same time!
Your reference to blinker fluid would indicate that you think changing fork oil is just as meaningless.
I suppose it's really about what you consider proper maintenance.
I have a friend who's dad hasn't changed the engine oil in his suburban in 50K miles or more and maintains nothing else on it unless it wears out or fails.
On the oil, he simply adds a quart if it gets low and keeps on driving it. He takes 1000 mile trips in it all the time and he always gets there. (although he does seem to visit an auto repair shop at least once on every long trip to fix something that has failed during the trip) I mention because it's simply amazing the amount of neglect a modern vehicle will tolerate before it actually strands you.
To that point, I bet you could buy a stock goldwing and only do oil changes every 15K miles and replace brake pads and tires when they wear but never touch brake fluid, radiator, rear drive, clutch fluid, spark plugs or valves and the bike would go well over 100K miles before it failed. It wouldn't be as good as new as it would slowly deteriorate in performance and safety, but it would still be able to ride cross country after 100K miles of neglect.
Now...ask me if I'd want to actually ride a bike that had been maintained like that and the answer would be a definite no. I over maintain my bike so that when I take off on a 6000 mile trip, I'm not worried about having a problem and I'm not spending part of my vacation at a repair shop or riding a bike that is messed up and making do until I get home.
