Well I have now done around 1000 miles on these tyres (E-08). The 140 rear section has not made any difference to either the speedo or the handling.
There is pleanty of room for it to fit. the bike turns in well ans is stable in corners. It has been quite wet and cold since fitteing them so I have not pushed them yet.

The rear gets plenty of heat into it however the front does not. The front after nearly 1000 miles still has all of its moldings on it includeing the centre line that goes round the circumfrance of the tyre. It is for this reason that I have not pushed my luck or the bike in the wet and cold conditions that we have been suffering. Having said that I have not had any moments either.

I have dropped the front by a few PSI from the 33 I normally run down to 30 to try to get some more heat into it. I think it is just sycological as like i said there have been no slides or scary moments.

Over all I am happy. I think they will last for a while especially the front!!
