Ha Giang Loop - Driving motorbike

Hi,

Me and my gf plan on checking out the loop; I'm looking for some insight in the drivability of the loop, or some experiences.

We both have full motorcycle licenses, used to busy european cities. experience on highway, backroads etc. Not much mountain riding but we both learned and drive manuals back home (4cyl naked bikes)
Are cautious drivers and have common sense.

Seems like some people advise against self riding but looking for some more detail.

Please let me know if you have some thought!
