The rear rim on my GPz750 is marked J18xMT3.00
I think the standard fitment was a 130/80 (although it's got a 120/90 on at the mo).
Can I fit a 140/70 here ? - I don't see any clearance issues, so it's only if it's safe on the rim...

Don't quote me on it but I seem to remember Avon producing wider section tyres for small rims. Might be worth a quick google.
