When I went to Kawasaki's ticket to ride event here locally last year, I participated in two of the group rides. I rode the Ninja 1000 and the ZG-14 Concours.
It was amusing to hear all the bikes go 'clunk' and lurch forward very slightly almost in unison, when we were given the cue and all shifted into first gear from neutral, regardless of the exact model. It's a Kawi thing, apparently.
I have that nagging worry about breaking a tooth off a gear or something when the clunk happens, but as I haven't read of anyone here shearing off teeth on a regular basis, with 150,000 miles plus on some of these bikes, apparently the transmission is built to take this. I've read about a few final drive hutch gears being sheared off/stripped every now and then, though, but that seems to happen while riding, not while parked...
