what do most of u run?
i heard the thinner the tire the better for carving ?

 

stock

 

120/70 & 180/55

 

The best tire size is OEM to your bike.

 

OEM all the way. If you want "performance" just use different tires. A lot of people here use the Michelin 2CT something or other, I have Shinkos on mine, and I'll be trying out Pirelli's come changing time.

Unless you're ONLY drag racing, or stunting, would I even RECOMMEND changing the tire size.

 

I use the 2CT front and rear with stock sizes and they seem to grip really well!

 

I run stock. I figure Honda did their research ahead of time and put the best size on stock.

 

what is stock size again?

 

look at the side of your tire....120/70 in the front, 180/55 around back.

 

google the make and model of your bike. There are factory specs listed for almost every bike.
