Bigger rear tire.

[Pro-4X_8975]

I've searched and searched, but cant seem to find what i'm looking for. What is the easiest swing arm swap to fit a 180 tire on the back?

You can fit some years of R6 swinger, but it requires major surgery to the frame and arm. There is no 'easiest' swap for this.

Why do you want to do this? The FZR is as agile as it is because of the tire selection; all you'll do is slow the steering.

Go buy a new bike. There is absolutely ZERO reason to put a 180 on the fzr. Any swap to fit a 180 is going ruin everything good about the fzr. Don't tell me it's because you want a better selection of rubber. You didn't even make mention to the fact you need a 17" wheel swap. A 160 can be done with minimal work and is more than enough to handle anything you can do to the FZR. If you want the look of a wider tire you really should pick up a different bike. If you want a bike that corners extremely well, stick a 150 on there and be done with it.
