I did this road a month back. It is spectacular. The hills drop into the sea cut by valleys. People mostly live in the valleys. So you are constantly climbing out of the valleys up, up into the hills looking down on the Black and then diving down into the next valley. Quite hard work, but worth it. Stunning scenery, nice people along the way - just watch out for blind bends. Even though there is hardly any traffic the road is quite narrow and any traffic coming around those bends is generally in the middle of the road. Only saw one motorcyclist in two days.
very low traffic... mostly you are alone with nature... mountainous and coastal road... you can see fantastic gideros bay, inceburun, hamsilos bay on this route... every motorcyclist should do this route...
