Dual Sport Tires for Skorpion?

[Bluejay]

I bought my Tour back in July and have since logged a few thousand miles. Now it's time to change the back tire, and I'd really like to put something on that can comfortably navigate the dirt roads surrounding my house. I'm guessing something in an 80/20 tread should be fine. The problem is, I have yet to find anything in a 110 width for the front (I'm running stock rims). I hate to put the effort into a d/s on the back if I can't find one for the front. Will I be asking for trouble if I run a 120/70-17 up front? The rear doesn't seem to be a problem, although many of them I'm finding tend to be a higher aspect ratio. I suppose if that's a problem, I can always delete the hugger fender. I'm also open to any other suggestions, aside from "Get a proper dual sport bike for that."
