SATO RACING Shift Spindle Holder for the 2020+ Kawasaki Ninja ZX-25R/RR and 2023+ ZX-4R/RR reinforces the shift linkage by reducing lateral play in the spindle shaft during shifts, for more consistent and precise shifting and extra durability in heavy-duty use. Gold anodized billet aluminum with a Teflon inner bushing.

NOTE: Shift Spindle Holder includes hardware for installation together with the stock sprocket cover. For installation without this cover in place, an additional collar approx. 17mm in length is required.
