Introduction:
JY110 Cylinder Head – The Heart of 110cc Daily-Ride Engines
For owners of the JY110—an iconic 110cc lightweight motorcycle designed for daily commutes, short-distance trips, and urban mobility—investing in durable, well-matched engine parts is key to maintaining consistent performance. The JY110 Cylinder Head stands out as a purpose-built solution, crafted to complement the JY110’s compact design while delivering the reliability and fuel efficiency that daily riders depend on. As the core component of the cylinder assembly, it seals the combustion chamber, houses essential valves and spark plugs, and directly influences critical factors like fuel economy, low-end torque, and the engine’s ability to handle stop-and-go city traffic or rural backroads. Whether you’re restoring a JY110 with authentic motorcycle parts or upgrading a 110cc utility tricycle (common for small-scale cargo or personal use) with dependable tricycle parts, the JY110 Cylinder Head offers the perfect blend of fit, efficiency, and longevity for 110cc lightweight vehicles.
Cylinder bore: φ49 mm – This precision-machined small bore is tailor-made for the JY110’s 110cc displacement, enabling smooth piston movement and efficient air-fuel mixing within the cylinder. The 49mm diameter generates just the right amount of combustion pressure for steady, low-end torque—ideal for navigating crowded streets, climbing gentle slopes, or carrying light loads—while keeping fuel consumption ultra-low. For riders who prioritize cost-effective daily travel, this balance between power and efficiency is a defining advantage.
Excircle: φ57 mm – The compact outer diameter is engineered to fit the JY110’s narrow engine housing perfectly, eliminating the need for modifications or custom adjustments. This snug fit enhances structural stability, reduces unwanted vibration (a common concern in lightweight vehicles), and ensures seamless compatibility with the JY110’s original motorcycle parts. For owners looking to preserve their bike’s factory-level handling and compact profile, this compatibility is non-negotiable.
Headspace: 64.8 mm – This carefully calculated headspace optimizes the JY110’s compression ratio for both efficiency and thermal management. It provides ample room for valve operation while facilitating effective heat dissipation—critical for preventing overheating during prolonged slow-speed rides (such as rush-hour commutes) and ensuring consistent performance in varying weather, from humid summers to cool winters.
Total length: 92 mm – The 92mm length complements the JY110’s streamlined engine bay, avoiding unnecessary bulk that could add weight or hinder maneuverability. This compact design also makes it a versatile upgrade for 110cc utility tricycles (often used for grocery runs, small deliveries, or rural transportation), where space is limited. As a tricycle part, it fits easily into tight engine layouts without sacrificing functionality.
Discharge volume: 102CM – This displacement closely matches the JY110’s factory 110cc output, ensuring the Cylinder Head works in perfect harmony with the engine’s existing components. The 102CM volume delivers the JY110’s signature reliable low-end torque, making it easy to start from a stop, cruise at 40-50 km/h (ideal for urban speeds), or carry a small passenger without straining the engine.
These specifications aren’t just technical details—they reflect the JY110’s “practical, everyday” identity, ensuring the JY110 Cylinder Head lives up to the bike’s reputation for hassle-free mobility.
JY110 Motorcycle Compatibility – It’s a direct replacement for all JY110 variants, including base models and upgraded editions. Whether you’re repairing a well-used JY110 that’s been on the road for years or restoring an older model to its original condition, this head fits seamlessly with the bike’s original engine parts. It preserves the JY110’s lightweight handling and fuel efficiency, ensuring your daily rides remain as smooth and cost-effective as when you first bought the bike.
110cc Tricycle Compatibility – For owners of 110cc utility tricycles (popular for personal use, small deliveries, or rural transportation), the JY110 Cylinder Head is a reliable upgrade. Its 92mm length and 102CM displacement fit most 110cc tricycle engine setups, making it a cost-effective tricycle part that brings JY110-level reliability to these workhorse vehicles. Whether you’re hauling a few bags of groceries or tools to a backyard project, this head ensures your tricycle’s engine runs consistently.
This compatibility means the JY110 Cylinder Head isn’t just a replacement for the JY110—it’s a flexible solution for anyone with a 110cc lightweight vehicle.
JY110-Specific Engineering – Unlike generic heads that “fit most” 110cc engines, this head is built exclusively for the JY110’s design. It matches the bike’s compression ratio, valve alignment, and engine dimensions exactly—no compromises on performance or fit.
Lightweight Efficiency Focus – It’s optimized for the JY110’s core purpose: daily, fuel-efficient travel. Generic heads often prioritize power over efficiency, but the JY110 Cylinder Head keeps the bike’s lightweight, cost-effective strengths intact.
Multi-Vehicle Value – It works for both JY110 motorcycles and 110cc tricycles, so you don’t need to buy separate motorcycle parts or tricycle parts if you own multiple small vehicles.
