Shrug.. plenty of Suzuki Bandits 1200 and 600 can be found cheap, plenty reliable and likely to last forever. Classic UJM with reasonably modern suspension, brakes etc. Lots of parts around, maintenance is entirely conventional, upgrades are well understood and specified these days and make a big difference. I probably have $1k in upgrades on it now, some new, some salvage & craigslist.
I take my 1200 anywhere the bike has a reasonable chance of having traction... heck I took my old Volusia cruiser down logging roads until I ran out of ground clearance.
