Start in Greenville, Ohio, take State Route 121 south. Pass through Fort Jefferson (6 miles), then New Madison (11) miles to New Paris (21 miles). Take SR 320 for access to US 40 and I-70.
This is the best motorcycle road in Darke county!! SR 121 generally runs parallel with some small stream valleys, with plenty curves and some hills the farther south you drive, especially once you pass through New Madison. Between New Madison and New Paris contains the best scenery and most hills and curves as the countryside gets more rugged and wooded.
Road condition is average to above-average. Lots of fun curves and a few nice hills with good scenery (considering this is generally flat farmland)
Jim's Drive-In on the south edge of Greenville, great spanish hot-dogs (Apr-Aug). The Snack Shop just as you enter New Madison offers lots snadwiches, pizza and ice cream. Good food at a fair price. Gas up on the south edge of New Madison, or in New Paris. Visit a couple of the antique shops in New Paris.
