Found an awesome loop this weekend on the Supermoto.
Probably pretty close to 70/30 asphalt/dirt. The dirt is all forest roads so not technical, but you can really get the bike sliding if you wanna The asphalt is twisty too.
Probably 65-70 mi. so gas not a problem.
There is also easy beginner trail riding that parallels one of the dirt roads for 6+ mi. if you want a bit more challenge.
I am thinking next Sat 7/18, meet in Sedalia @ the Jarre Mart gas station @ 9:30am out @ 9:45.
