Hi guys.i have a thundercat and am thinking of replacing my tires.i am thinking of getting michelin pilot power. And how will a 180 tire fit instead of a 160.thanks

it won't. largest on the Cat rear is a 170.

All you will do is cost yourself more money!

Stick to the original sizes, the bikes suspension and chassis settings wre all calculated to work best with what Mr. yam fitted as standard.

A wider rear tyre will slow your turn in and do nasty things to your steering in general. If you are looking to improve your bikes handling, spend the extra on something stickier rather than bigger.
