I don't think that affects the difference in width or clearance between an MT/130 and MU/140 tyres!
I have just fitted a 140 wide Avon Venom on my 1990 bike. Had to remove the rubber 'curtain' from the inside of the belt guard to get it on. There is about 1/8 to 3/16 inch clearance between tyre edge and belt. May be a little more room on later models?
I wrote to Avon for some info on using their tyres on my bike and they recommended fitting a 140, especially for touring fully laden two up. They reckon the factory 130 is marginal for that use, which is why I took their advice. I have no idea if Venoms are bias tyres or not!
