I had a chance to talk to Al Ludington at VRI last year for about 15 minutes. Since I have a ZX-7R I had a particular interest in finding out what the status of any forthcoming changes would be.
The impression I got from him was that Kawasaki was waiting to find out what was going to happen with the WSBK and AMA tech specs in2003/4. If the rules are indeed changed to allow 1000cc displacement regardless of cylinder numbers Kawasaki will most likely abandon the manufactur of the 7R. Instead they would focus on the 6 and 9.
