90-91 FZ 750 rear tyre

[Hangtight]

Hi all,

This year I'm resolved to get my poor neglected FZ750 back on the road. A new pair of tyres would seem to be a good idea as it's been sitting on the existing ones for 4 years. I want to use a more modern tyre, but the only 18" rear fitment I can find is 160/60 18. Currently it's sitting on a 150/70. Is the 160 too big, or will it handle poorly?
Looking forward to responses, but in the meantime I'll be trawling through endless fitment lists!

What size is the rim? 3.5x18, 4.0x18, 4.5x18, 5.0x18?

A 3.5 maxes out with a 150
A 4.0 maxes out with a 160
A 4.5 & 5.0 should be very comfortable taking a 160 - 170

But the question of "too big" and therefore creating "poor handling" is arbitrary and should be left up to you and you alone. The FZR600 was designed for a 130 / 140 tire. I have a 180 on mine and love it. But some people would disagree.

From memory the rear rim is 4.5". 160 it will be with a little hackage applied to the chainguard!
