I love my zx14 logged almost 4,000 miles this season and not one complaint. The power is awesome the ride is smooth. It is a big bike and does not handle as good as the smaller bikes in the twisties but every time I take it out I find I can push it a little further than I thought and even though it is heavy it isn't awkward or unstable at slow speeds. I have rode 7-8hrs with no issues. My wife was not impressed with the passenger comfort so I picked up a concourse seat and she loves it now.
