The only tire I can currently mount up is a Pirelli MT21 in the 90/90-21 size. For gnarly single track riding, will the 90 width be much of a handling difference over the stock D605 80/100?

 

I've been running the Pirelli MT21 90/90-21 since the stocker was due for replacement. If there is difference in handling it's too subtle for me to have noticed. Great tire for the front. I have the Michelin AC-10 on the back, 100/100-18.

 

Thanks, ol'klx-er.
