If you just want to ride curves over and over again, try this Snake Sportbike Route. When we stay in Johnson City, TN over the Summer and Fall, we ride this almost every Sunday to practice riding curves. A lot of sport bikers use this route as their race track to practice getting their knee down and going fast around the curves. You most likely will see some of them especially on weekend afternoons when the weather is good. If they come up behind you when riding, just move to the right side of the road, signal them to pass, and slow down a touch, and they happily will ride on by. The US-421 Track Boys have a fun poster in the Shady Valley General Store and use the store as their hang out when riding this road.
When we ride this route, we like to stay to the right side of the road (like riding a bicycle) when going around the curves just in case a biker or car driver driving in the opposite direction goes over the yellow center line. It is a good practice, staying to the right side of the road, because it is pretty common for a car or motorcycle to ride over the center line on this road. In addition, staying to the right side of the road will increase the degree of difficulty when riding the curves, making for much better practicing. Plus if you misjudge a curve and take it too fast or too early, you will be way over on the right side so if your screw-up causes you to swing out to the left, you have less chance of going over the center line yourself! Forget about perfecting hitting the apex if you stay to the right side though; that is for track days on a track.
US-421 from Shady Valley to Mountain City has been resurfaced (as of July 2017) and widened slightly (16 more inches) and riding it is now heaven! The road surface from Shady Valley to South Holston Lake is starting to get pretty beat up especially just north of Shady Valley. We have heard that that part of the road will be re-patched Summer 2017 and then repaved some time in Summer 2018. We are hoping that the work crew doing the patch job for Summer 2017 are motorcycle riders so they will take care to smooth it out.
In the detailed ride route shown below, I have pointed out easy turn around points. That way you can ride to north of Mountain City, turn around, ride through Shady Valley, turn around after finishing up the majority of curves on the Snake and head back to Shady Valley. Then it is always nice to take a break at the Shady Valley Country Store, to get a drink and bathroom break, and to chat with and watch all the motorcyclists with motorcycles visiting the store. It can get pretty busy on the weekends.
After a rest, you can get back on the bike and head north on US-421 N, go through the fun curves again and then stay on US-421 N to TN-44 which will take you back to Johnson City if you follow the detailed route plan below.
