ZXI Speed

I purchased a 1998 Kawasaki 1100ZXI recently. I have read different arcticles on this watercraft about top speed. Could you please you please give me the performance data on this model? Its my understanding that the newer units are a little slower. One post stated that the 1998 Kawasaki 1100ZXI Jet Ski finally hit the 60mph mark on your radar gun., Then another arcticle stated 58mph. The watercraft gives me a great ride and it's fun to ride. I have been riding watercraft for over 8 yrs. Thanks for your help.

R.J. We radared the 1100ZXI at 56.1 mph. Kawasaki claimed a top speed of about 54-55 mph on the ZXI, and it is very unlikely that any stock ZXI has reached 60mph.
