Here we have a Genuine Kawasaki part that fits loads of models Z1000/Z650/Z1R/Z1300
Regards fitment.. please ask if you're unsure.
Part number: 43054 004 (rear brake caliper/piston dust seal)
This part is new old stock and has never been fitted....

Perfect to add that finishing touch to that mint restoration or to keep in stock as a spare!!
Either way you don't know when you'll see another!!
