Them's the brakes

I find that about every 2nd rides, on my H6R; my front brake pads need adjusting; With the bike clamped on my stand, wheels off the ground, I give the front wheel a spin, then turn it to the right, to it's max ( till it stops at the stop) The spinning wheel stops; I find that the pads are off center.

I'll adjust it (center the pads and it's good to go) then 2 or 3 rides later, I got to do it again.

but the M6R I don't have this issue. Is this a common thing or is there something wrong with it?

I fuss with these bike's a lot, and don't mind minor maintenance; Just that one bike does and the other doesn't; It's got me wondering. I welcome in put on this matter.
