Please add profiles for Motorcycles (similar to what you have done for bicycles or cars). With the Motorcycle profile somewhere between Car and Bicycles, it needs to include the slight unpaved roads as well. I’m living in Thailand (and work in Singapore) and doing a lot of Enduro (and dirt bike) style on-/offroad trips (Gelände/Strasse, unbefestigt/befestigt). When I choose the car profile at ORS, it stops routing if some unpaved segments are between, when I choose Mountain bike (sub-) profile it will calculated the shortest route, what then goes straight through jungle tracks, not always fun with a bigger motorcycle. The closest, what come to a (normal adventure) motorcycle profile is the Bicycle Street-bike profile, but this will then choose sometime some small paths and foot bridges, which are in urban areas not allowed for Motorcycles.
If there is a chance for sub profiles under Motorcycle, it would be:
Street-bike (paved only, similar to cars), Enduro/Adventure (mix of all paved and some light unpaved gravel roads (OSM uses the words: unpaved, gravel, compacted, (but not Mud/dirt/Sand, etc) ) and Dirt bike (all roads, streets, paths, except for foot-paths only for people, similar to mountain bikes),
It would help if there is a slider to choose from ‘fastest’ (mainly the fast paved main roads) to ‘shortest/direct’ connection (mainly smaller / curvier side roads and dirt roads). Ideally it should come with a tick box for unpaved/dirt roads allowed or not. Many motorcycle drivers do not want to drive unpaved at all, when many other are looking out for dirt roads.
Most motorcycle drivers also prefer curvy (often the smaller) roads, which means, if there is an option for such ‘preferences’ this would be the icing on the cake.
Looking forward to your reply and happy to help with further details when required.
