TITANIUM KTM Super Duke 1290R Sprocket carrier nuts
Part number: 54310086200
These aren't the sprocket nuts but the sprocket carrier nuts. Just ask if you need the sprocket nuts because I have Titanium all metal locking nuts as well as the sprocket bolts.
I design all parts in house in CAD so you'll get a lot of unique products unlike the other sellers.
Half the weight of the steel part but also corrosion proof, making it easier to remove when doing maintenance.
