Normal wear and tear is ,well, normal. A lot depends on how it is stowed when not in use. Is it kept outside in the elements? Is it kept in the garage? Is it kept in the living room in a controlled environment? Sounds like you are meticulous on maintenance. Keep on keeping on. Keep on trucking.
Yes, I agree, our bikes are rather like trucks, or maybe tanks..!
But seriously- after that many miles suspension and all fuel hoses, including the vapor rail hose would need some attention, most likely.
Any Nitrile/Buna N/NBR (the type of rubber used for fuel and oil) hoses have a 20 year service life, and will probably be as hard as a rock about now. If you've never disturbed them, they may be okay for a while longer even in their aged state, but as soon as you start moving them around, you'll see they're done.
Same thing for the o-rings on the fuel and vapor rails and carb gaskets. I'm doing mine right now, for the second time on my '97 Tourer.
Water and brake line hoses are usually EPDM rubber and last much longer, at least in theory...
