For owners of 150cc vehicles that demand more than basic performance—whether workhorse motorcycles for long-haul commutes, rugged light-duty haulers, or utility tricycles for daily cargo transport—finding engine parts that blend strength, efficiency, and long-lasting durability is essential. The TITAN150 Cylinder Head lives up to its name, standing out as a robust solution engineered to meet the tough demands of 150cc engines in high-use scenarios. As a core component of the cylinder assembly, it seals the cylinder’s top, houses critical parts like valves and spark plugs, and directly influences combustion efficiency, torque output, and the engine’s ability to withstand repeated stress. Whether you’re maintaining a TITAN150 motorcycle (or comparable 150cc models) and need heavy-duty motorcycle parts, or upgrading a 150cc utility tricycle with reliable tricycle parts, the TITAN150 Cylinder Head delivers consistent, rugged performance that aligns with the “workhorse” role of many 150cc vehicles.
Cylinder bore: φ57.3 mm – This perfectly sized bore matches 150cc engine displacement, enabling smooth piston movement and optimal fuel-air mixing within the cylinder. The 57.3mm diameter strikes a critical balance: it provides ample combustion space for robust low-end torque (ideal for hauling small loads or climbing steep rural roads) while maintaining fuel efficiency for daily long-distance use.
Excircle: φ72 mm – The outer diameter is designed for a rock-solid fit with standard 150cc engine housings, adding structural rigidity to handle the vibrations and stress of frequent use. This compatibility eliminates the need for custom modifications, making it easy to integrate with existing motorcycle parts or tricycle parts setups—saving time on installation.
Headspace: 62.3 mm – This streamlined headspace is engineered to optimize compression ratio for 150cc engines in high-stress scenarios. It provides just enough room for valve operation while boosting combustion pressure, ensuring consistent power delivery whether you’re idling in traffic, cruising at 65km/h, or navigating unpaved paths with a light load.
Total length: 90 mm – Its compact 90mm length is tailored to 150cc engine bays, balancing space efficiency with structural strength. The design fits seamlessly into both sleek work motorcycles and sturdier utility tricycles, without adding unnecessary bulk that could impact handling or load capacity.
Discharge volume: 149CM – This displacement aligns nearly perfectly with 150cc engine output, ensuring the Cylinder Head works in harmony with the engine’s overall design. The 149CM volume delivers reliable, steady power—strong enough to carry moderate cargo (on tricycles) or tackle 50km+ daily commutes (on motorcycles) without compromising fuel economy.
Motorcycle Compatibility: It’s designed as a direct replacement for TITAN150 motorcycles and fits most 150cc work-focused bikes (e.g., Honda CG150, Yamaha XT150). Whether you’re repairing a motorcycle used for daily inter-city commutes or upgrading an older model to handle heavier use, the TITAN150 Cylinder Head integrates seamlessly with existing motorcycle parts.
Tricycle Compatibility: For 150cc utility tricycles used for small-scale commercial transport (e.g., delivering produce, carrying construction materials) or rural tasks (e.g., hauling farm tools), the TITAN150 Cylinder Head is a reliable upgrade. It works with standard 150cc tricycle engine setups, providing the extra durability needed for daily hauling—making it a cost-effective choice for tricycle parts users.
This compatibility ensures that no matter your 150cc work vehicle type, the TITAN150 Cylinder Head is a plug-and-play solution that works in harmony with your existing engine parts.
Toughness-by-Design: Unlike generic heads calibrated for casual use, it’s engineered for the stress of daily hauling, long commutes, and rough terrain—living up to the “TITAN” name.
Work-Focused Versatility: It performs equally well in motorcycles and tricycles, making it a one-stop solution for users who own multiple work vehicles (no need to stock separate motorcycle parts or tricycle parts).
Long-Term Cost Savings: While cheap engine parts need frequent replacement, the TITAN150’s reinforced materials mean it lasts 2–3 times longer—saving you money on replacements and downtime over time.
