I rode this on a BMW F950 GS in February 2023. Best Road I´ve been on. Hardly any traffic, good surface and never ending corners. Police roadblocks every 20 km, looking for immigrants from Myanmar, but no cameras or traps. \r\n\r\nThere are many many great roads in the north of Thailand, but after riding this my mate and I stopped and just burst into laughter. A joy of a road.
One of the best rides you will have anywhere in the world. From valleys into the mountains, rice patties and tea fields. This is an amazing to trip to do over 3-5 days. Curvy, hilly, challenging with some of the best scenery around.
