I wouldn't on a bike. Wet clutch so you don't really want your oil any more slippy.

Old thread I know and a contentious subject......

I’ve got an old XJR400 with a bit of clutch rattle. Recently changed the oil and today I thought I’d add some of this stuff I had kicking around to see if it made a difference.

Fired it up from cold and removed the oil filler cap. Added a small amount of ZX1 while running and almost instantly could hear a difference in the engine sound. Might be snake oil and yet to be proved long term but certainly a discernible difference in engine smoothness.
