"DUH" seriously, probably shouldnt make assumptions. First off, I had to order the tires, also how is adding a 1/4" of contact patch going to make a difference for the worse. These are mid 70's 360's not liter superbikes. Maybe we should keep people from putting modern suspension (forks and swingarms=wider wheels=wider tires) on these cafes. If what your saying is true its not going to handle very well. Unless I am misunderstanding what you are saying.
Yeah, I probably shouldn't make assumptions, but with limited information it's easy to fill in the gaps. ;D
Does anyone in your local shop actually have any experience of CB360's? (run them at 90+mph or even ridden one?)
The stock rims are marginal width for stock tyres.
When you fit wider tyre to stock rim, you REDUCE contact patch.
The tyre does get taller but it doesn't 'spread' to give a 'wider' tyre
If you fit wider rims, fitting wider tyres isn't a problem, modern sportbikes use a 6" wide rim for a 180~190mm tyre ( roughly 7.4" wide)
Front rim on stock 360 is 1.60" rear, 1.85".
All the measurements are taken on the inside, where the bead sits, the outside measurements are about 3/4" or more wider so sportbike would have a ~7" rim with 7.4" tyre, less than quarter inch 'overhang' (about 0.2" each side)
CB360 with a 2.4" 'outside width', a 3.50" tyre doesn't get 0.55 'overhang' each side, it gets a bit less as tyre beads are squeezed, taller tyre is less stable.
If you had any idea what you were taking about you wouldn't have asked here in the first place.
Handling is worse with oversize tyres on stock rims, bike is unstable, you didn't misunderstand anything.
I was jut relating a recent experience as I have a pair of wheels with oversize tyres fitted
