My passion for the ZRX1100 began when I first spotted it in the pages of Cycle Canada. I'm still not sure I can describe exactly what I found so arresting about the appearance of the ZRX. I simply found it beautiful.
It didn't become real for me until I went to the Kawasaki booth at the 1999 SUPERSHOW and sat on a ZRX. When we met in the metal, so to speak. Look at the expression on my face.
The ZRX 1100 was well received by motorcycle journalists world wide, and Canada was no exception; Cycle Canada's coverage of the ZRX 1100 was quite positive.
The American motorcycling publication Cycle World rated the ZRX 1100 the best 'Naked Bike' of 1999.
