Efficient Cooling for Enhanced Engine Performance
Maintaining proper engine temperature is essential for reliable performance. We have been manufacturing aluminum casting components since 2011 and have supplied similar structural parts to Sany Heavy Industry, where thermal management is critical.
This Motorcycle Cylinder Head is designed for engine air intake and combustion processes while providing efficient heat dissipation.
It is manufactured from ADC12 or A380 high-strength aluminum using die casting. The optimized cooling fin structure improves heat dissipation, helping maintain lower engine temperatures and stable performance.
Precision Engineering – Backed by Data
Our die casting process ensures consistent product quality and dimensional accuracy.
The sealing surface flatness is controlled within ≤0.04 mm, ensuring a tight seal with the head gasket and preventing leakage.
The valve guide hole is machined to IT7 grade, with surface roughness maintained at Ra ≤ 1.6 μm for reliable operation.
This Motorcycle Cylinder Head is suitable for engines ranging from 100 cc to 400 cc and is compatible with both air-cooled and water-cooled systems, delivering stable performance across various conditions.

Lightweight Design for High-Speed Operation
We provide more than components-we deliver reliable performance solutions.
This Motorcycle Cylinder Head features a lightweight design with efficient heat dissipation, making it suitable for high-RPM operation and vibration conditions.
It is compatible with a wide range of applications, including scooters, street motorcycles, and small utility engines.
Manufactured from ADC12 or A380 aluminum, it operates within a temperature range of -30°C to 280°C.
With over a decade of experience since 2011, we are committed to delivering high-precision engine components that support long-term performance.
