FZ16 Cylinder : Unlock 160cc Sporty Power with Precision Engineered Parts
Introduction:
FZ16 Cylinder Head – The Core of 160cc Engine Performance
Cylinder bore: φ58 mm – This precision-machined bore is tailored to the FZ16’s 160cc displacement, enabling seamless piston movement and optimal air-fuel mixing within the cylinder. The 58mm diameter generates stronger combustion pressure, resulting in snappier acceleration—ideal for overtaking slower vehicles on highways or navigating busy urban intersections—while keeping fuel consumption in check. For riders who crave sporty thrills but need economical daily transport, this balance is a game-changer.
Excircle: φ72 mm – The outer diameter is engineered to fit the FZ16’s engine housing perfectly, eliminating the need for modifications or custom adjustments. This tight fit enhances structural stability, reduces vibration at high RPMs (a common issue in sporty motorcycles), and ensures compatibility with the FZ16’s original motorcycle parts. For owners who want to preserve their bike’s factory-tuned handling, this compatibility is essential.
Headspace: 73.3 mm – This carefully calculated headspace optimizes the FZ16’s compression ratio, striking a balance between power and thermal efficiency. It provides ample room for valve operation and efficient heat dissipation, preventing engine overheating during prolonged rides—such as 2-hour weekend trips or daily commutes in hot weather—and ensuring consistent performance in all conditions, from cold winter mornings to scorching summer afternoons.
Total length: 95 mm – The compact 95mm length aligns with the FZ16’s streamlined engine bay, avoiding unnecessary bulk that could hinder the bike’s agile handling. This design also makes it a versatile upgrade for 150-160cc utility tricycles with limited engine space, serving as a reliable tricycle part for small-scale cargo hauling, such as delivering packages or transporting farm tools.
Discharge volume: 153CM – This displacement closely matches the FZ16’s factory 160cc output, ensuring the Cylinder Head works in perfect harmony with the engine’s existing components. The 153CM volume delivers the FZ16’s signature low-to-mid-range torque, making it easy to climb steep hills, cruise at 80-90 km/h on highways, or navigate heavy city traffic without straining the engine.
Wide Compatibility: Fit for FZ16 and 150-160cc Vehicles
FZ16 motorcycle compatibility – It’s a direct replacement for all FZ16 variants, including the FZ16 V2 and FZ16 S. Whether you’re repairing a well-loved FZ16 that’s been on the road for years or restoring an older model to its former glory, this head fits seamlessly with the bike’s original engine parts. It preserves the FZ16’s sporty handling and responsive throttle, ensuring your ride feels like it did when it rolled off the factory floor.
150-160cc tricycle compatibility – For owners of 150-160cc utility tricycles used for small-scale commercial or rural transport, the FZ16 Cylinder Head is a robust upgrade. Its 95mm length and 153CM displacement fit most tricycle engine setups, making it a cost-effective tricycle part that brings FZ16-level reliability to workhorse vehicles. Whether you’re hauling produce to market or tools to a job site, this head ensures your tricycle’s engine runs smoothly and efficiently.
Why Choose FZ16 Cylinder Head Over Generic Engine Parts
FZ16-specific engineering – Unlike generic heads that are “one-size-fits-all,” this head is built exclusively for the FZ16’s engine. It matches the bike’s performance, fitment, and handling exactly—no compromises.
Balance of power and practicality – It delivers the FZ16’s signature sporty torque while maintaining fuel efficiency. Whether you’re riding for fun or commuting to work, it meets all your needs.
Multi-vehicle value – It works for both FZ16 motorcycles and 150-160cc tricycles, so you don’t need to buy separate motorcycle parts or tricycle parts if you own multiple vehicles.
