Probably Pirellis, though I'm sure Jack will chime in about the Avons.

Sport demons if you want to stick with the stock 110/130 sizes. Our Breva has them on and they are pretty nice.


But the best DOT street tire available that will fit a GS's stock rims are
"Diablo" SS tires in 110/70 & 150/60.

They just require modifying (beating a dint in to clear the edge of the tire) or replacing the rear brake stay arm.

ok what is beating a dint?

The OEM rear brake stay is that piece of square tubing connecting the rear brake caliper to the swingarm. The way its mounted, it cuts into the plane that a wider rear tire would occupy.  The quickest way to gain the clearance for a wider tire is to mark on the arm where the widest part of the tire is, remove the arm, and then beat that part of it flat(er) with a hammer while trying to keep it fairly straight.

A more elegant solution is to replace the stay arm with another one fabricated from either thinner stock (1/2"x1/4" etc.) or by building one with a "kink" in it.
