Bikes can handle more than the reviewers would lead you to believe. You don't need a 990 Adventurer just because the roads are less than ideal. A sport bike with springs that aren't too stiff would be fine on any thing that could be called a paved road. I've actually ridden my RS250 on a 5 mile fire road and it was just fine. (I know your not looking for that type of bike but just as an example)
Secondly your only too old if you think you are. My father is in his 70's he's racing motorcycles and goes on 8 hour rides on a bike most old people would say they couldn't even ride a mile (RS250)
