While looking for a first dual sport, I continue to come across late 70's/early 80's bikes, oftentimes appearing in decent shape. Would anything such as a 1979 Honda xl 500 be a decent first dual sport? I'm guessing no, since I don't really see many on here, but was wondering how viable an option an older bike would be if it was in good shape, or does a bike from the 90's just run all over something older in every way. The kind of riding I plan on doing is fire roads and trails. Nothing too crazy.
