Hi all, sharing my experience with Givi tanklock systems for CB's 2017 models
BF25, originally designed to work on Honda AT fit almost perfectly - "horseshoe" have different orientation on HAT ( 90 degree CCW ) so if you want to install it , 3 small plastic triangle pitch need to be removed from tanklock module, simply task with sharp knife.

Interesting is that tanklock added to the set BF25 is higher than standard tanklock delivered with tankbag - so you have a choice, I give a try with lower one. Bolts and bushes in set fit perfectly.
not bad look even on red tank, right ?
Model of tankbag i choose is XS307, before it will fit, the tanklock base have to be shift fully forward - another easy task with philips , what more is "fully legal" :-) as system is designed that way.
So...finally on the bike
as you may find out, tankbag fits perfectly and "hoovering" above the tank - low/standard tanklock ring do the job for me
But..check this out, BF20 may do the job as well
