Kz1000 tyre size

#1 PostAuthor: pegleg » Thu Dec 18, 2025 10:26 pm

Having the wheels rebuilt and wondering about increasing the width of rear. Has anyone done this to fit into a Metmachex swingarm. I realise that this means a new rim but best choice please allowing for chain run as well. Thanks.

The widest rim you can fit to a stock 900/1000 frame without scalloping around the swingarm pivot for chain clearance is 5.5 inch with 180 tyre and you will need a 5/8ths offset front sprocket if going that wide..
I tend to use modern swingarms such as XJR1300 or GSXR etc in my builds so don't know the max width a Metmachex will accept..

A 4.5 inch rim with a 160 looks plenty big on a Zed without going over the top. it also helps to have a 530 chain areas of a stock 630. Still need a sprocket offset.
