You can use most any sport bike type tire in the one size larger 150/60/17 size. I think the stock DRZ-SM tire is a 140. Not many choices in this 140 size.

Avon, Bridgestone, Continental, Dunlop, Metzeler, Michelin, Pirelli, etc.

Plenty of choices. Nice to have but not important to have a 'SM' specific tire like the ContiForce SM. Some people who commute on their SM use sport-touring type tires.

While I agree it's not critical, if you do any kind of 'fast' or aggressive corner riding, GET A SM RATED TIRE. A sportbike tire is, while the same size, designed for a MUCH heavier bike. They take longer to heat up with less weight, so if you go for a ride up into some twisties your tires aren't going to grip as much (with a sportbike rated tire).

Now, if you just use the bike for commuting and such, then supertireguy is right, just go for a tire that fits your bike.

Also, glad to hear the Conti rear works with a Dunlop front, I have to do the exact same thing in the next few weeks haha.
