Just the titanium clutch nut and countershaft/front sprocket nut, not the bolts, and the slipper is still active in this clutch, as it's not drag raced/launched hard from a stop.
I put them in the '18 Gsxr1k when I put in ceramic transmission bearings, and 520mm chain/sprocket conversion, as a 'why not' when trying to loose weight/rotating mass from the drivetrain.
