Hi Guys , i have a 2012 , 48 and wondering if anyone knows what is the widest rear  tire i can go on the stock rims (if possible) without  changing the handling too much  Currently runing the stock tires below

(Michelin® Scorcher® “31” front and rear):

- Rear – Scorcher® “31” 150/80B16 77H
 Cheers

Biggest rim/tyre Metz 880 marathons 160 60 18, 4.25 inch rim assuming all sporty frames are the same.

Std rim would should be a 160 width with no swingarm mods.
