I have a 2016, and it has handguards and a slip-on from the Crappy witch.
I never even mounted the passenger grabrails from new.
I do not like how the extra tank in the airfilter cavity forces you to fit a small little filter.
Loctite makes a really great retaining compound that I have used to 'fill" gaps between bearing outers and casings.
It does not fill the cavity, but if the gap is not too big, it literally "glues" the bearing into the hub/casing.
Iwould not mount it as is, withoit at least the retaining...
