Best I have found for motorcycle routing

This app is great for routing if you know where you want to go. The free version only allows six waypoints, so you must purchase the full version if you want to go over that. There is a way around that. Just break your trip into sections that contain only six waypoints. A pain in the butt but it is cheap. Good luck and ride safe!
