Shinko 244 on the back and Dunlop 606 on front of my DR650 have served me very well over the years.Looking great so far @Kevin Werner. Did you source tires yet? My TX650A had Bridgestone Trailwings on it when I bought it, as did my new DR650, but I think those Shinko 244s are better. They are well regarded by the DR650 community.
Had a Dunlop 606 on the back initially but the noise and accelerated wear of that rear tire was too much, thus the switch to the Shinko 244, I'll never use anything else now.
