properly torqued nothing should fall off. Mirror topside cosmetic cap, I used double sided sticky 3m VHB tape (tiny piece) to hold those in. Check everything before every ride. Or better yet, go over everything and torque everything slightly more for carefree assurance while riding. I found my reservoir caps barely finger tight when I received mine. I was surprised they didn't leak. Some bolts can't get to under fairings, I am praying those are all ok.
