Introduction:
Key Specifications at a Glance:
Engineered for Quad-Displacement Fit.Every dimension of the Cylinder Head T120 is calibrated to optimize performance across 107cc, 124cc, 125cc, and 130cc engines, ensuring seamless integration with critical engine parts. Here’s a detailed breakdown of its core specs:
Model: T120 – Purpose-built for 107cc/124cc/125cc/130cc 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 four 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 and load-bearing tricycles.
Superior Material Selection for Longevity.The Cylinder Head T120 is crafted from high-grade 3000-series aluminum alloy, chosen for its exceptional strength-to-weight ratio, resistance to high temperatures (up to 300°C), and impact durability. Unlike low-quality motorcycle parts or tricycle parts that warp under the heat of high-RPM small-displacement cycles or crack under heavy loads, this alloy retains its shape and precision over time. It also undergoes a ceramic anti-corrosion coating to protect against moisture, road salt, and industrial dust—common threats to engine parts in urban, suburban, and rural environments. This material choice ensures the Cylinder Head T120 resists wear and tear, extending the lifespan of both the part and the engine it serves by up to 40% compared to generic alternatives.
Quad-Displacement Flexibility: Adapts to 107CM, 124CM, 125CM, and 130CM discharge volumes, eliminating the need to stock multiple parts and reducing inventory costs by up to 75%.
Broad Compatibility: Fits most 107cc-130cc motorcycles and tricycles, simplifying repairs, reducing guesswork, and saving time for mechanics.
Durable, High-Performance Design: High-grade aluminum alloy, advanced heat management, and anti-corrosion coating ensure it withstands daily use, lowering maintenance costs for vehicle owners.
