If you're only looking to get ~100K from a Honda, you've got your head up your arse.
A Honda 2.0 / 2.2 Liter Accord should, like the 3.0 Vulcan, easily surpass 250,000 miles / 400,000 km w/o TBO. The car around the engine, in either case, or both, for that matter, will fatigue & rust out in the time that it takes an ordinary owner to reach that benchmark.
The problem with the Honda is that it's an interference engine and proper attention to the timing belt(s) is imperative(also, opt for the stick shift to avoid trans problems). I've never seen a timing chain on a Vulcan fail.
