i lived in germeny for 20 years and i have to tell you, a more motorcycle friendly country you could not find. just about everyone respects the motorcyclist rights on the road.
speaking of scenery and good riding, darwin, a run along the Mosel river is a must with a stop in cochem. on a nice day there could be as many 5000 bikes in town. it is also close to the Nuerburgring. also a must ride.
have fun in germany.
autobahns: when you absolutely have to get there.
