I'm cheap as fuck and really pretty dedicated to enjoying whatever. I've got an old 81 XJ550 seca that I ride all the time, and that thing's probably seen more offroad than alotta the KLRs and DRZ's out there. not that it's good at it, but it's still silly and fun to beat the shit outta whatever you got. Like, you don't need a Tonka to play trucks in a sandbox, you can still have alotta fun if you're willing to pretend a Barbie is a truck.
I dunno, I guess I can't really get outta this moped mentality where what I consider underpowered is WAYYYYY below what other people consider underpowered. Like the KLR you can totally go highway speeds, I mean you're not going 100 for 10 hours straight, but you can cross country a DR350 and probably have a really fun time doing it. I mean LGN max just rode 2000 miles on a WR250 and my wife's run over 1000mi trips on a ninja 250.
I guess it depends who you are and what you're going for. Personally I'd take about anything, which means I'd be more than glad to keep what you're already selling. I'm not much help here.
I do love the Africa twins, but holy $$$$. Vstrom seem like a sweet deal tho. I look at them sometimes. I often consider selling my seca and my dirtbike and getting one thing that'd kinda do both. or getting a maxi scooter. But then inevitably come to the realization that it's not worth it. maybe the right deal will come someday
