Hello,
I want to share one of the most complete guidebooks of Romania. They are all dedicated to motorcyclists. The Carpathian 2 Wheels Guide has published two printed guidebooks: Apuseni Mountains and Touring Romania. Also they have a mobile app with routes: Touring Romania (iOS and Android). All guidebooks have English and German translations.
More details, free routes, photos and articles an be found on www.carpathian2wheelsguide.com

If you like the ideea, please share it.
Have a nice day!
