That's what I thought. I've ridden a few sports bikes and I just don't like them. So ill probably have to go with a drz or xrr and just take it easy on any long ridesDRZ or older TE610 maybe. Older KTMs are paint shakers, newer ones are too expensive... Maybe if you can find a KLX650 converted to a motard, might fit the budget too, and probably better for distance than the smaller displacement bikes.
Honestly, supermoto and long distance aren't usually spoken in the same sentence unless you mean the twin cylinder big supermotos. My 690 is about the minimum level of comfort I'd consider taking a REAL long ride on.
