DirtyGirl's Kawasaki ZRX 1100

Kawasaki ZRX 1100 - Manufacturers brochure image

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.

I'm not sure I actually thought any further than that. I just loved looking at it. I don't remember thinking about riding it, or thinking about it's motor. Not until later, after I'd sat on it, did I expand my speculations.

the 1999 North American International Motorcycle SUPERSHOW - my first seat on a ZRX

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.

After that it took a while to make it happen, and there were some obstacles to be considered (not the least of which was a 3" discrepancy between the seat height and my inseam). But I was convinced (devoted? sold? in love?), and it was only a matter of time...

Actually, just sitting on Rex makes me a grin!

Modifications to Verdis Rex

I get asked a fairly often about what I've done to my ZRX1100 and usually implicit in this question is the 'to make it more suitable for my size' part. Except for a custom seat, my ZRX 1100 is entirely stock.
