Fitment Guide
Best suited to 1P52FMH-pattern Lifan and Lifan-style 110cc horizontal engines.
- Lifan 1P52FMH 110cc – High. Direct engine-code match for the 52.4 mm head family.
- Lifan-style 110cc pit bikes – Medium. Suitable only where the engine code, stud pattern and dimensions match 1P52FMH.
Fitment is based on the engine pattern, not just the badge on the bike or ATV. Chinese manufacturers often used different engines under the same model name.
Before Ordering – Required Checks
- Check the engine code stamped on the crankcase. A matching 1P52FMH code is the strongest indicator.
- Confirm the approximately 52.4 mm cylinder/head family.
- Compare the four main stud holes, cam-chain opening, oil passages, intake flange and exhaust port with the photos.
- If possible, confirm approximately 23 mm intake / 20 mm exhaust valve sizes.
- Do not assume every 110cc Chinese pit bike or ATV uses this head.

Installation Note
Correct cam timing, valve clearances, gasket orientation and cylinder-head torque are essential. Rotate the engine carefully by hand after timing and before starting to confirm the valves do not contact the piston.
