You're not going to get all the oil out during a change unless you put a lot of effort into it. Mine usually took right at 2 quarts sometimes a tad more...
See the SERVICE MANUAL amounts below.
Many vehicles have two or three oil capacities listed:
- the total capacity ie. if you received a totally dry engine from the factory and filled it,
- the amount that gets replaced when you also replace the filter,
- the amount that gets replaced when you leave the oil filter (which most people wouldn't do).
From the maintenance standpoint, you're not concerned with the first one, you'll never have an opportunity to fill a dry engine.
The pre-2015 Versys manual has this (on page 98):
1.7 L (1.8 US qt) (when filter is not removed)
1.9 L (2.0 US qt) (when filter is removed)
2.4 L (2.5 US qt) (when engine is completely dry)
And as others have said, when you're replacing oil, you might end up filling a bit more or less, depending on how thorough your draining was. Don't worry about leaving a few drops of old oil in, it's unavoidable....
2015 capacity (page 2-34, 2015 SERVICE MANUAL.)
1.6 L (1.7 US qt) - filter NOT removed
1.8 L (1.9 US qt) - filter removed
2.3 L (2.4 US qt) - DRY engine.
The REASON for the difference, between '15s and earlier Vs, is that the NEW V has the drain on the LEFT-side of the sump, NOT on the bottom. I'm pretty sure that the long "tit" hanging down, w/ the drain plug at the lowest point, accounts for THAT .1 L of oil....
Here's a pic of the '15 sump.
