NTV 650, 600 Revere. Good overlander?
Not in it's standard trim, granted, but would this bike have potential?
Thing is, twins are more versatile than singles, the Honda lump is solid, (proven in the Transalp and Deauville series) and it is shaft drive: a nice option in the 650 class that is otherwise the reserve of the 1000+ cc engines.
Finally, it also a comfy, economic bike.
A slightly longer rear shock, a 19/21 inch front and slightly longer forks, panniers and a screen and off you go...
Adventure: it's an experience, not a style!
(so ride what you like, but ride it somewhere new!)
