While the odd one will make it there, it would have to be extremely well maintained w/regular valve adjustments, oil changes, etc. Most bikes profit from a top end rebuild around 60,000 miles. The state of your bike is not unusual and should run all day long like it is
Mine needed it's first top end job at about 40,000. At 75,000, it definitely needed to be bored. I doubt very much any of these could go 100,000 without some serious work.
