Confirm the engine and cylinder specification
Check the model, year and engine type, including two-stroke or four-stroke details where stated. If the engine or cylinder has been changed, identify the specification now fitted. Have the cylinder's measurements and condition confirmed by your engine builder before selecting a size.
Read the kit's contents and requirements
Check the exact reference for included rings, pin, circlips and any gaskets; do not infer contents from the word “kit”. Where compression or other build requirements are stated, compare them with the intended engine specification. Browse gaskets and seals for separately required components.
Can I select the size from the markings on the old piston?
Use those markings to help identify the old part, then confirm the size needed for the cylinder now. They do not establish its present measurements or condition. If a grade or oversize must be selected, agree it with your engine builder before ordering.
Are two kits for the same model always interchangeable?
Compare the complete specifications, including engine type, piston size and any stated compression or build requirements. A shared model application does not mean every option is suitable for the same build. Ask for clarification if the difference between references is unclear.
Does one piston kit cover the whole engine?
Check the quantity of pistons and components supplied by the exact listing. Do not assume a kit covers every cylinder. Compare its contents with the parts list for the work being planned.
Can I buy the rings, pin or circlips separately?
Browse piston rings and wrist pins and circlips for separate listings. Match each replacement to the exact piston reference and size; the vehicle model alone may not identify the piston fitted.
Compare the complete model, year and part number before choosing a part.
