Maintenance is very labor intensive. You'll learn that as soon as you change the air filter.
My dad is a 50+ year veteran motorcycle mechanic who has worked on just about every major brand to come down the pike. He once worked on a K1200LT and called it one of the biggest pains he ever worked on, right up there with Can-Am Spyders.
I'm not saying they're bad motorcycles. I'm saying they're a pain to work on if you do your own work, and expensive as hell if you pay the dealer to do it (because it's a time-intensive pain for them, too).
A 23-year old bike will need maintenance. Keep it in mind.
