In the realm of engine parts, the piston serves as the "driving force" of combustion—converting fuel energy into mechanical motion that powers motorcycles and tricycles. The Piston WH100 stands as a premium choice for 100cc systems, engineered to excel as both motorcycle parts and tricycle parts. Unlike generic pistons that compromise on fit and performance, the WH100 is calibrated to meet the exact demands of 100cc engines, ensuring seamless integration with critical components like piston rings and cylinder walls. Whether you’re repairing a daily commuter motorcycle, a utility tricycle, or maintaining a fleet of 100cc vehicles, the Piston WH100 delivers durability, efficiency, and consistent power—making it a trusted solution for mechanics and vehicle owners alike.
Model: WH100 – Purpose-built for 100cc engines, designed to replace OEM parts in a wide range of motorcycles and tricycles.
CYL DIA (Cylinder Diameter): 50 – A 50mm diameter that creates a tight, uniform seal with the cylinder bore, maximizing compression and minimizing energy loss.
TOTAL HIGH (Total Height): 37 – A 37mm total height that aligns with 100cc engine block dimensions, ensuring proper piston-to-head clearance and avoiding mechanical interference.
COMP DIST (Compression Distance): 19 – An 19mm compression distance that optimizes the engine’s compression ratio, enhancing combustion efficiency and power output.
Dimensional Inspection: Laser scanning verifies all key specs (cylinder diameter, total height, compression distance, etc.) to ensure precision and consistency.
Pressure Testing: Pistons are subjected to high-pressure simulations to confirm resistance to combustion forces and prevent deformation.
Wear & Heat Testing: Units undergo 500+ hours of simulated engine operation to validate durability under extreme temperatures and load conditions.
Piston Ring Compatibility Testing: Each piston is paired with the specified 1.01.02.0 piston rings to ensure a perfect seal and optimal performance.
RING (Piston Ring Sizes): 1.01.02.0 – Precision-sized piston rings (1.0mm top, 1.0mm second, 2.0mm oil control) that seal combustion gases, reduce oil consumption, and protect cylinder walls from wear.
PIN DIA (Piston Pin Diameter): 13 – A 13mm piston pin diameter that balances strength and weight, ensuring smooth movement within the connecting rod.
PIN LENGTH (Piston Pin Length): 38 – A 38mm piston pin length that provides stable support for the piston, distributing load evenly to prevent premature damage.
Precision Fit: Calibrated to 100cc engine requirements with exact dimensions (50mm CYL DIA, 37mm TOTAL HIGH, etc.) for seamless integration.
Durable Design: High-grade aluminum alloy and anti-corrosion treatment ensure longevity, even in demanding use cases.
Performance Boost: Optimized compression distance and piston ring compatibility enhance power, fuel efficiency, and engine lifespan.
