So I go down a lot of dirt roads and I was looking for a bit more traction. Problem is, very few dual sport tires come in the right sizes to fit my little Duke 390.

I went up from the stock 150/60 rear to a 160/60 rear. I went up from the 110/70 front to the 120/70 front.

They fit with no rub. The rear has plenty of room but the front has just enough.

It does not seem that going to a 160 rear has changed the ride feeling much. I know many forums said a 160 on a 4inch rim is to big but I found several manufacturers sites said the 160 is ok.
