Introduction:
In the competitive landscape of engine parts, the cylinder head serves as the "combustion control center"—and the Cylinder Head W063 stands out as a flexible solution for 140cc and 150cc systems. Engineered to excel as both motorcycle parts and tricycle parts, this component seals the combustion chamber, regulates airflow, and manages heat to deliver consistent power across two key displacement ranges. Unlike generic Cylinder Head options that restrict users to a single engine size, the W063 adapts seamlessly to 140CM and 150CM discharge volumes, making it a top choice for mechanics servicing mixed fleets and vehicle owners upgrading 150cc-class motorcycles or utility tricycles. Whether you’re repairing a fuel-efficient commuter bike, a heavy-duty cargo tricycle, or a mid-performance motorcycle, the Cylinder Head W063 balances precision, durability, and broad compatibility—essential for meeting the diverse demands of 140cc/150cc engines.
Key Specifications at a Glance:
Engineered for Dual-Displacement Fit.Every dimension of the Cylinder Head W063 is calibrated to optimize performance for 140cc and 150cc engines, ensuring seamless integration with critical engine parts. Here’s a detailed breakdown of its core specs:
Model: W063 – Purpose-built for 140cc/150cc engines, eliminating the need for separate Cylinder Head options for each displacement and simplifying parts inventory management.
Cylinder Bore: φ56 – A precisely machined 56mm bore that creates the ideal compression space for both 140CM and 150CM discharge volumes. This uniform diameter maximizes air-fuel mixture efficiency, avoiding power loss common with ill-sized cylinder bores in engines of varying displacements.
Excircle: φ60 – A 60mm outer diameter that forms a tight, leak-proof seal with cylinder blocks and gaskets. This tolerance prevents compression drops and oil leaks—critical for maintaining engine health in vibration-prone motorcycles (e.g., off-road models) and load-bearing tricycles (e.g., cargo haulers).
Headspace: 78.35 – A 78.35mm clearance between the Cylinder Head and piston, engineered to prevent mechanical interference while accommodating thermal expansion. This gap protects internal parts from damage, even during prolonged use in stop-and-go urban traffic or rough rural terrain.
Total Length: 98.8 – A 98.8mm total length that fits seamlessly into 150cc-class engine bays, avoiding interference with surrounding motorcycle parts or tricycle parts. Its robust structure ensures easy installation without drilling, welding, or custom modifications—saving time for mechanics and DIY users alike.
Discharge Volume: 140/150CM – Unique dual-displacement compatibility that adapts to 140cc (light-duty tricycles, entry-level motorcycles) and 150cc (mainstream commuters, heavy-duty tricycles) engine requirements. This flexibility reduces inventory costs for parts suppliers and eliminates the risk of purchasing the wrong Cylinder Head for vehicle owners.
Dual-Displacement Flexibility: Adapts to 140CM and 150CM discharge volumes, eliminating the need to stock multiple parts and reducing inventory costs.
Broad Compatibility: Fits most 140cc/150cc motorcycles and tricycles, simplifying repairs and upgrades for mechanics and vehicle owners.
Durable, High-Performance Design: High-grade aluminum alloy, advanced heat management, and rigorous testing ensure it withstands daily use and harsh conditions—lowering maintenance costs over time.
