How long will my Honda shadow 600 last?

I just bought a 1995 Honda Shadow VLX 600. It has 24 thousand miles on it, got it for 1500$. It has no problems, no leaks, clean, no rust, been garage kept, regular oil changes, runs like a spanked monkey. Now i'm wondering if it will make 5000 more miles, or 30,000 more. What do bikes regularly make it to?

You hit on the key. If the bike has been maintained properly, they can get nearly automotive levels of miles before needing major service. My GSXR1000 was well maintained and not abused. It had nearly 40,000 miles on it when I sold it and it was still running perfectly and showed no signs that was going to change any time soon. It had for seals replaced, the clutch done a few times, and chains sprockets, brakes and tires that it consumed on a regular basis, but if you keep after those things, and make sure the rest of the routine work is done, you can count on years and years of reliable service.
