Description

Kawasaki Jet Ski SX-R 160 Complete Top End Rebuild Kit +.50mm

When measurements show additional piston clearance is needed, matching the correct top-end parts early can help simplify assembly. This complete top end rebuild kit fits 2024 Kawasaki SX-R 160 models and combines upper-engine service components with +.50mm piston kits for rebuilds that require oversize piston selection.

This package works well for repair shops, PWC owners, and engine builders who already confirmed piston sizing and want a focused upper-engine refresh without expanding into valve replacement.

If your rebuild remains standard bore, compare the SX-R 160 complete top end rebuild kit (STD).

• Top End Gasket Set

Fitment

Select the Correct Piston Size

This listing includes +.50mm piston kits only while keeping the same upper-engine rebuild scope. However, if your measurements support a smaller oversize option, compare the SX-R 160 complete top end rebuild kit +.25mm.

Additionally, if your rebuild includes intake and exhaust valve replacement, review the SX-R 160 master top end rebuild kit +.50mm.
