When it comes to riding in Germany
- don't speed in towns and villages - cameras everywhere (and it's dangerous)
- stay off the Autobahns - normal roads are great
- carry a first aid kit - the law - unopened - may be requested from the emergency services if needed - checks made when stopped - fine if not carried or opened
- carry a reflective vest - the law - fine if not carried
- plan a rough route - the B500 through Black Forest is worth a detour
Otherwise, just have fun.
