I feel like I've typed this in a ton of threads already... but the ZX14 is a great tourer. I never did any 2up touring, but I've done many 4 hour straight highway runs(with only gas stops), and a bunch of back road days. It's amazing. When mine got stolen I went with the triumph Sprint GT, similar handling/chassis, less power, but awesome factory luggage, better stock seat/position, and better MPGs. But it was a close decision, if the ZX wasn't stolen, I'd have it set up with better hard luggage and bar risers.
