Hi All, what size welly can I get on back of my Z1R I might sound stupid but I can't bloody remember what mates did back back in 88, on theirs, can't ask, only in touch with a few of them these days so I know 120 goes in standard and im limited on the front coz of mudguard, can you get a 130 in? I did it on the shaftie and its bloody close but ok

One thing to remember is that different tyres, even on the same size - do differ in actual width.

It is very possible to find one model tyre with a badged 120 width, being as wide as someone else's 130 ...and vice versa

That is down to tyre sizing being nominal rather than definitive. They are allowed (IIRC) a 6% size differential from the sidewall listed measurement.
That can be up or down.

Pirelli sometimes have slightly fatter tyres within the listed parameters. I have a 150/70-17 Pirelli Phantom and it is much fatter than two other 150/70 tyres I compared it with (Maxxis and Michelin).

It is visibly as well as factually fatter. Pick a tyre size but look at it in person to judge which one you feel looks beefiest, if beef is your goal

So a 120/90x18 it is then, Rufforth on Saturday And see the Tyremen weather permitting of course, I don't like to miss it

Anyfin bigger than 120 wears the crap out of the chain guard just sayin

And F**ks up the handling ( even worse than it already is )

ohlins going on the back progressives in the front, iv'e not forgotten

Keith's spot on right about the chain guard, I tried a 130 on mine and it tried to eat the guard---be careful
