We have added the Kurviger routing option to motorcycle trips. It's the one kurviger.de calls 'Curvy route. Prefer curves and slopes, while avoiding cities and highways'. We have also received permission from Kurviger to use one more option: 'Fast and curvy route. Low amount of curves and detours, big parts may be on the motorway.' as well as the preference to avoid unpaved roads. We'll add both options to Furkot soon. Meanwhile, give it a try. The feature requires Furkot Pass - if you need more time to test beyond one day of the 'try it out' option, please contact me at firstname.lastname@example.org . Make sure to set trip or route to Motorcycle travel mode to enable curvy routes either per trip or for a selected route segment (see the screenshot). Thank you for suggesting this feature.
