Cylinder bore: φ56.5 mm – This precisely calibrated bore size enables smooth piston movement, minimizing friction and maximizing fuel combustion efficiency within the cylinder, directly enhancing the engine’s responsiveness for daily use.
Excircle: φ62.5 mm – The outer diameter is designed to fit seamlessly with standard 150cc engine housings, allowing for hassle-free integration with existing motorcycle parts or tricycle parts setups—no complex modifications required.
Headspace: 77 mm – This well-sized dimension provides ample room for valve operation and effective heat dissipation, preventing engine overheating even during extended city rides or short-haul cargo trips, ensuring stable performance.
Total length: 105 mm – Its compact yet robust structure ensures compatibility with a wide range of 150cc engine configurations without sacrificing structural strength, adapting to the design needs of both motorcycles and tricycles.
Discharge volume: 149CM – This optimized displacement capacity is tailor-made for 150cc engines, delivering balanced torque and power—ideal for daily commuting, light off-roading, and small-scale tricycle cargo transport.
Whether you own a 150cc commuter motorcycle for daily urban travel, a lightweight off-road bike for weekend getaways, or a 150cc tricycle for small-scale cargo transport (such as delivering groceries or packages), the SB150 Cylinder Head integrates seamlessly with your engine. This compatibility not only simplifies the installation process but also ensures your vehicle operates at peak performance, as the Cylinder Head works in perfect harmony with other engine parts to deliver optimal results.
