When I moved to Georgia 12 years ago my motorcycle endorsment did not transfer to my Georgia license. Its ok, I didn't have a motorcycle. I didn't miss having a MC license except when we traveled. I like to rent motorcycles. Sometimes they let me rent without a motorcycle license, sometimes not. So, the right thing to do was to get my mototcycle endorsement in Georgia. It requires a 2 day class that can also serve as your road test. The DDS (DMV) supplies the bikes, instructor and everything else for the $250 fee. I never took a motorcycle class in my life. I was self-taught in NY and I passed the very difficult road test in Lyons NY in 1980.
I now have what I need for my GA motorcycle endoresement. I also learned some stuff. I am glad it is over. Fun and somewhat stressful. The class was a bit like a martial arts class or Tai-chi. Practicing un-natual actions until they become familiar.
The class was at my airport off runway 25. I found it to be a great distraction watching my plane with students go around the pattern during class.
