Important Fitment Notes
- Honda used KPH-family cylinders such as 12100-KPH-700 / 12100-KPH-900 on many Wave 125 variants in this period.
- Do not apply this listing automatically to 2012-on Wave 125 models: Honda changed many variants to the KYZ cylinder family from 2012.
- Check the cylinder reference, oil-temperature-sensor arrangement and gasket profiles before ordering.
Before Ordering
- Confirm the original cylinder is the KPH-pattern type
- Confirm a 52.4 mm standard bore and 13 mm piston pin
- Compare cylinder height, lower spigot, stud spacing and cam-chain tunnel with the photographs
- Compare the head and base gasket profiles with the original parts
- Check the oil-temperature-sensor / sensor-guard arrangement on later fuel-injected models
Installation
Top-end engine work requires correct piston-ring orientation and end gaps, secure piston-pin clips, correct cam timing, clean gasket faces and the proper Honda torque procedure. Professional installation is recommended if you are not experienced with four-stroke engine rebuilding.
