More power than the ZZR, rode well (it was pissing down raining the day I rode it though). The lack of fairing might start to become a problem with the extended freeway runs to the city too.
Compared the the spewzi GS-500 that it competes against it is a superior machine in every way; water cooled, better suspension, more modern engine, much better frame.
