Pirelli used to make a dual sport tire called a MT60 Corsa RS in a 120/70 17. I used them on a supermoto. Last about 4k miles. The rear DOT knob you could consider installing on your front rim would be 120/90/17. It is the same width as your front but taller. Maybe too tall.
The Buell Ulysses used Dunlop D616 tires and it had your same wheel sizes. They really aren't true dirt tires but if mostly dry they should work well enough on the Dempster. Another street tire with bigger grooves is the Pirelli Scorpion Sync, which comes on the Ducati MultiStrada.
You really need a 19 or 21 inch front wheel to get proper dual sport tires where you need it most.
