Ha Giang Loop

Hey guys I really wanna go on the Ha Giang Loop tour in September in a small group, but I've never been on a motorbike before and I'm lowkey quite scared for my safety. I also heard about the partying stuff and drunk easy riders. Based on my research so far, Road Kings seems to be one of the most reputable companies to go with. Can anyone share any advice on how to be safe, and if Road Kings will really make my experience good? Thank you!
