It looks like the tank bag ring is held by 4 screws: on the 2016 AL7 SV, the pair of tank screw holes closest to the bars are 85mm apart, the pair closest to the seat are 60mm apart and the distance between any adjacent tank screws is 52mm.
Disclaimer: Any discrepancy in measurement is caused by me being long sighted in one eye. (my excuse and I'm sticking to it).
