I have more often than not found that the quantity of oil in owners manuals for motorcycles is excessive. Sometimes it probably makes no difference but on others this excess oil ends up in the airbox. This is the case for all brands and models I've owned from BMW, Kawasaki, HD, Honda, Yamaha, Guzzi, and on.
When changing oil on my 2014 CB1100 I warmed it up first then let the oil drain on its center stand while I removed the filter. After it completely stopped dripping around 10 minutes later I installed the new filter and put the plug back in finger tight, parked it on the side stand, removed the plug and over 1/2 a cup more came out. Plug back in, tip the bike to the right and hold it there for 10 seconds, back up on the center stand, removed the plug and almost another 1/2 cup drained out over night.
Next day I added 3.5 qts, started the bike letting it idle for a minute, then checked again a few minutes later and had to add some (but not all) of the remaining 1/2 qt to get it to just below the top of the sight glass. So I'm saying probably around 3.75 qts puts mine near max.
