Boost Your Vehicle's Performance with CBF125 Cylinder
Cylinder bore: φ52.4 mm – This precisely sized bore is perfectly matched to 125cc engine displacement, enabling smooth piston movement and optimal fuel-air mixing within the cylinder. The 52.4mm diameter strikes a balance between power and efficiency: it provides enough combustion space for responsive acceleration (ideal for merging into traffic) while keeping fuel consumption in check for daily commutes.
Excircle: φ66 mm – The outer diameter is designed for a secure fit with standard 125cc engine housings, ensuring structural stability while accommodating the slightly larger components of 125cc engines (compared to smaller 110cc models). This compatibility eliminates the need for modifications, making it easy to integrate with existing motorcycle parts or tricycle parts setups.
Headspace: 62.3 mm – This streamlined headspace is engineered to optimize compression ratio for 125cc engines. It provides just enough room for valve operation while enhancing combustion pressure—critical for delivering consistent low-end torque (for city driving) and mid-range power (for occasional highway stretches or light off-roading).
Total length: 90 mm – Its compact 90mm length is tailored to 125cc engine bays, which often need to balance space for performance components with overall vehicle weight. The design fits seamlessly into both sleek commuter motorcycles and sturdier utility tricycles, without sacrificing structural strength or adding unnecessary bulk.
Discharge volume: 124CM – This displacement is nearly identical to the 125cc engine’s target output, ensuring the Cylinder Head works in perfect harmony with the engine’s overall design. The 124CM volume delivers reliable power: it’s strong enough for carrying small loads (on tricycles) or navigating hilly roads (on motorcycles) while maintaining excellent fuel efficiency.
Motorcycle Compatibility: It’s designed as a direct replacement for CBF125 motorcycles and fits most 125cc commuter and light off-road bikes (e.g., Honda CB125F, Yamaha YBR125). Whether you’re repairing a trusted daily rider or upgrading an older model to restore performance, the CBF125 Cylinder Head integrates seamlessly with existing motorcycle parts.
Tricycle Compatibility: For 125cc utility tricycles used for small-scale cargo transport (e.g., delivering packages, carrying garden supplies), the CBF125 Cylinder Head is a compatible upgrade. It works with standard 125cc tricycle engine setups, providing the extra durability needed for hauling light loads—making it a cost-effective choice for tricycle parts users.
Balanced Power and Fuel Efficiency: The φ52.4 mm cylinder bore and 124CM discharge volume optimize combustion, delivering up to 10% better fuel efficiency compared to worn or low-quality cylinder heads—critical for daily commuters who want to save on gas. At the same time, it provides a noticeable boost in mid-range power, making it easier to overtake slower vehicles or climb gentle hills.
Smooth Performance Across Conditions: Small-displacement engines often struggle with inconsistent performance in varying conditions, but the CBF125 Cylinder Head’s optimized headspace ensures smooth operation—whether you’re idling in traffic, cruising on a highway, or navigating unpaved paths. This versatility makes it ideal for 125cc vehicles that are used for more than just commuting.
Reduced Maintenance Costs: The precision seal and durable materials minimize wear on other engine parts (like piston rings, gaskets, and valves), reducing the frequency of repairs. For busy users who don’t have time for frequent maintenance, this means more time on the road and less money spent on replacement parts.
125cc-Specific Engineering: Its specifications (φ52.4 mm bore, 62.3mm headspace) are tailored to 125cc engines—unlike generic heads that may be calibrated for smaller or larger displacements, leading to poor performance or premature wear.
Versatility for Diverse Use Cases: It’s designed to perform well in both city commutes and light off-road/utility tasks, making it a one-stop solution for 125cc vehicle owners who use their vehicles for more than just one purpose.
Long-Term Value: While cheap engine parts may seem affordable upfront, they often fail quickly—costing you more in replacements and downtime. The CBF125 Cylinder Head’s premium materials and precision machining mean it lasts for years, delivering better value over time.
