how wide of a tire can i put on a 1989 yamaha fzr 600 motorcycle?
Why? A bigger tire will add mass that most be overcome by the torque, which will increase chain wear and bend over the tangs between the links. Your rear will tend to low side easier on gravely turns. Your two tires will not have the same contact in turns as the front is the guide that determines the turn line. The rear will have less pressure against the ground for grip. Your choice.
Nice to know someobody's still running around on an FZR600. Great bike, and standing the test of time better than the CBR of the same era. Cheapest easiest way to get yourself a lower bike is to back the preload right off on the back shock. This will lower the back end. It's achieved by unscrewing the nut at the bottom of the back shock absorber. The bike may feel a bit softer to ride, a little less responsive to bumps in the road, but it shouldn't handle badly. If the steering feels a bit slow, or you want a little more leg room, you can drop the forks through the yokes a centimetre or two. This is easy to do, no special equipment needed but not a one-person job. Try these before spending money on shorter shocks and thinner seats - you may be surprised by the results. Good luck.

Some of the web FZR forums show that alot of folks go to a one-size-narrower width rear tire to gain lean angle. This makes the bike turn in a bit quicker. A wider tire will have the opposite effect . you will turn in much slower, but your straight line stability may be a bit better. Liekly not worth it. Also, you should measure the clearance you currently have .there may be no room for more width without rubbing the swingarm.
