ZX600A vs ZX600C
There is not a dramatic difference between the two in terms of performance. Here's some info. and stats, which I am giving entirely by memory. Might be a bit off, but if so, not by much at all.
Rear Wheel horsepower: Best I've seen dynoed on an A model was 63. The C models typically put down anywhere between 70-72.
Top Speeds: "A" model tops out at about 130, C model is good for 135-137.
Quarter mile times: Low 12's for the A, High 11's for the C. About a 3/10th of a second difference.
Wet Weight: A model is 482 lbs. C is 457.
In terms of handling, not much difference between them as they both rode on 16-inch wheels, similar suspension components, and the same size tires. Interestingly enough, the frame of the earlier A model was actually more sophisticated, being a box section perimeter style design as opposed to the C model's traditional round tube double cradle. C model feels (and is) a much narrower bike. I would expect that the narrowness combined with 25 less pounds of weight would make the C model a bit more flickable than the A.
