Introduction:
In the dynamic landscape of engine parts, the cylinder head is the "combustion controller" that defines performance—and the Cylinder Head F120 redefines flexibility for 107cc, 120cc, and 125cc 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 three key displacement ranges. Unlike generic Cylinder Head options that force users to choose a single engine size, the F120 adapts seamlessly to 107CM, 120CM, and 125CM discharge volumes, making it a game-changer for mechanics servicing mixed fleets and vehicle owners upgrading 120cc-class motorcycles or utility tricycles. Whether you’re repairing a fuel-efficient commuter bike, a light-duty cargo tricycle, or a mid-performance motorcycle, the Cylinder Head F120 balances precision, durability, and broad compatibility—essential for meeting the diverse demands of 107cc-125cc engines.
Key Specifications at a Glance:
Engineered for Triple-Displacement Fit.Every dimension of the Cylinder Head F120 is calibrated to optimize performance across 107cc, 120cc, and 125cc engines, ensuring seamless integration with critical engine parts. Here’s a detailed breakdown of its core specs:
Model: F120 – Purpose-built for 107cc/120cc/125cc engines, eliminating the need for separate Cylinder Head options for each displacement and simplifying parts inventory.
Cylinder Bore: φ52.4 – A precisely machined 52.4mm bore that creates the ideal compression space for all three 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: φ56.3 – A 56.3mm 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., food delivery vehicles).
Headspace: 78.2 – A 78.2mm 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: 96.5 – A 96.5mm total length that fits seamlessly into 120cc-class engine bays, avoiding interference with surrounding motorcycle parts or tricycle parts. Its compact yet robust structure ensures easy installation without drilling, welding, or custom modifications—saving time for mechanics and DIY users.
Discharge Volume: 107/120/125CM – Unique triple-displacement compatibility that adapts to 107cc (compact tricycles), 120cc (mainstream commuters), and 125cc (mid-performance motorcycles) engine requirements. This flexibility reduces inventory costs for parts suppliers and eliminates the risk of purchasing the wrong Cylinder Head for vehicle owners.
Triple-Displacement Flexibility: Adapts to 107CM, 120CM, and 125CM discharge volumes, eliminating the need to stock multiple parts and reducing inventory costs.
Broad Compatibility: Fits most 107cc-125cc 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.
