Nothing against the street triple here. Buying any used bike and wanting to set off very shortly on a long-distance adventure can be rough (or painless if you're lucky). You haven't had time yet for a thorough shakedown/getting all maintenance to a known point (eg. is the clutch marginal and starts slipping when it gets really hot, how old is the brake fluid, valves in spec, chain/sprockets good enough to last the trip (without lots of km on it already trending wear is hard), etc etc). Less popular bikes make it harder to solve some of those issues on the road.
FWIW, I bought the mini, put 300 km on it driving around and then set off for huntsville (ontario not alabama). On the way home, the bottom end let go and I finished the trip 12 hours later on the back of a tow truck. Replaced the motor and haven't had major issues since.
