Model: GY6-150 – Purpose-built for 150cc GY6-series engines, ensuring seamless integration with the platform’s design.
Cylinder Bore: φ57.4 – A 57.4mm bore, precisely machined to enhance air-fuel mixture compression, boosting combustion efficiency and power output.
Excircle: φ60.5 – A 60.5mm outer diameter that forms a tight, leak-proof seal with adjacent engine parts, maintaining critical compression levels.
Headspace: 68.8 – A 68.8mm clearance between the cylinder head and piston, engineered to prevent mechanical interference while accommodating thermal expansion during operation.
Total Length: 90 – A compact 90mm total length that fits perfectly within 150cc engine bays, avoiding interference with surrounding components.
Discharge Volume: 149CM³ – A 149cm³ displacement, perfectly aligned with 150cc engine requirements to balance airflow, fuel intake, and power delivery.
The Cylinder Head GY6-150 is a versatile solution for 150cc systems, compatible with most GY6-series motorcycles, scooters, and tricycles. Whether you’re servicing a fleet of commercial tricycles or upgrading a personal motorcycle, this cylinder head replaces OEM parts without modifications, ensuring a hassle-free fit. Its broad compatibility makes it a staple for mechanics stocking reliable engine parts, reducing the need for multiple specialized components.
Seamless compatibility with GY6-150 motorcycles and tricycles
Enhanced power output and fuel efficiency
Long-lasting durability against heat, corrosion, and wear
Easy installation with standard engine parts
