Kawasaki OEM 0.5 Oversize Piston Ring Set 13025-7009
The Kawasaki 13025-7009 Piston Ring Set is a genuine OEM 0.5 oversize service ring set used during engine rebuilding on select Kawasaki FR, FS, FT and FX V-Twin engines.
Kawasaki's official parts description is RING-SET-PISTON L,0.5. This is an oversize service part and should not be confused with the standard-size piston ring set used in the same engines.
Important: 13025-7009 is an oversize piston ring set.
Do not order 13025-7009 as a replacement for standard rings unless the engine has been machined/rebuilt for the corresponding oversize piston configuration.
Verify the complete Kawasaki engine model and specification before ordering. Kawasaki uses both standard and oversize piston components within these engine families.

13025-7009 Is Not the Standard Piston Ring Set
Kawasaki parts diagrams commonly list two different ring-set options in the same piston/crankshaft section:
- 13008-series ring set – standard-size piston rings
- 13025-7009 – RING-SET-PISTON L,0.5, oversize service rings
This distinction is critical during an engine rebuild. A standard piston should use the ring set specified for the standard piston, while 13025-7009 is intended for the corresponding oversize service configuration.
Matching Kawasaki Oversize Piston 13029-7010
Kawasaki piston/crankshaft diagrams list 13029-7010 PISTON-ENGINE L,0.5 alongside the 13025-7009 RING-SET-PISTON L,0.5.
This pairing is important when rebuilding an engine that has been prepared for the oversize service piston.
13029-7010 piston is sold separately. Do not assume that piston 13029-7010, piston pin, retaining clips or connecting rod are included with 13025-7009.
What Engines Use Kawasaki 13025-7009?
Kawasaki parts diagrams document 13025-7009 across numerous commercial and residential V-Twin engine specifications.
Documented engine families include select:
- Kawasaki FR651V
- Kawasaki FR691V
- Kawasaki FR730V
- Kawasaki FS651V
- Kawasaki FS691V
- Kawasaki FS730V
- Kawasaki FT651V
- Kawasaki FT691V
- Kawasaki FT730V
- Kawasaki FX651V
- Kawasaki FX691V
- Kawasaki FX730V
Exact documented examples include FR651V-AS43, FR691V-CS51, FR730V-AS25, FS651V-BS24, FS651V-CS20, FT651V-AS00, FX651V-AS13 and numerous related specifications.
This list does not mean every specification or production version within those engine families requires the oversize rings.
When Is an Oversize Piston Ring Set Used?
Oversize piston components are service parts used during certain engine-rebuilding procedures when the cylinder has been machined and the matching oversize piston is required.
Whether an engine requires standard or oversize piston components should be determined by proper engine inspection and measurement according to Kawasaki service information.
Do not install oversize rings simply because an engine has low compression, oil consumption or worn standard piston rings.
Standard vs. Oversize Kawasaki Piston Rings
On many applicable engines, Kawasaki lists a standard 13008-series piston ring set together with standard piston 13001-7027.
For the oversize service configuration, Kawasaki instead lists:
- 13025-7009 – Oversize Piston Ring Set
- 13029-7010 – Oversize Engine Piston
Use the parts specified for the actual cylinder and piston size being serviced.
