close,
andrew i think you are thinking of another bike. the first generation 600r was based off the gpz550 motor but the zx600r(not zx6r) is liquid cooled with 4 valve head but it only put out about 76hp at the crank at 10500rpms. 38ftlbs at 9 grand which isnt bad, (i think those are the right numbers). the bike almost weighed in at 500lbs. first year for the zx6r was 95, totally different beast. but the 600r was good for its day and by no means counted out. now it suffers from 80s tech but you can still get 80s to the wheel with pipe, filter and some major tuning i bet. i dont have any accel numbers for you but id guess 0-60 in under 6seconds.
this is the bike he is talking about
this is your bike
95-97 was the zx6r. or the 600F1-F3 ninja
85-87 was the 600A1-A3
