Every dimension of the CG180-A Piston is calibrated to maximize strength, load capacity, and compatibility, making it a standout in the engine parts market for 180cc heavy-duty vehicles:
  • CYL DIA (Cylinder Diameter): 59.6 mm – This precision-machined large diameter is tailor-made for 180cc engines, ensuring a tight, leak-free fit within the cylinder bore to preserve peak compression under high load. The 59.6mm size optimizes combustion pressure, delivering exceptional low-end torque (ideal for hauling 200+ kg cargo on tricycles or navigating rough terrain on motorcycles) while balancing fuel efficiency for cost-conscious commercial operators.

  • TOTAL HIGH (Total Height): 49.4 mm – The substantial total height is a defining strength, engineered to withstand the extreme combustion forces of 180cc engines under heavy load. It provides unmatched structural integrity, preventing warping or deformation even during prolonged high-torque operation, while fitting seamlessly into the CG180-A’s engine bay and most 180cc heavy-duty engine setups without modifications—ensuring compatibility with existing motorcycle parts or tricycle parts.

  • COMP DIST (Compression Distance): 26.9 mm – This carefully calculated distance optimizes the engine’s compression ratio for heavy-duty performance. It ensures efficient combustion in 180cc setups, generating enough power to climb steep hills with full cargo, traverse unpaved roads, or operate continuously for hours without straining the engine—essential for commercial tricycle fleets and professional riders.

  • Piston Ring Dimensions: 1.21.22.5 mm – The  (included) Piston ring set features ultra-thick 1.2mm primary/secondary compression rings and a 2.5mm oil control ring. This rugged design enhances sealing performance, prevents oil contamination of the combustion chamber, and resists wear from heavy load and prolonged use—critical for 180cc engines that operate under extreme conditions, such as commercial cargo transport or off-road work.

  • PIN DIA (Piston Pin Diameter): 15 mm – The 15mm piston pin is engineered for maximum strength, capable of handling the cyclic stresses of 180cc combustion under heavy load. Its robust diameter ensures a secure, low-friction connection to the connecting rod, supporting the piston’s ability to withstand the rigors of commercial use.

  • PIN LENGTH: 46 mm – This extended length provides stable, even support for the connecting rod, distributing pressure across the piston’s wrist pin boss to prevent lateral movement and premature wear. It ensures alignment even under extreme torque, safeguarding both the piston and rod from damage during heavy-load operation.

In the competitive landscape of 180cc engine parts, the CG180-A Piston excels through industrial-grade materials and heavy-duty engineering:
  • High-Strength Forged Steel-Reinforced Aluminum Alloy – Constructed from forged 6061-T6 aluminum alloy with steel reinforcement at critical stress points, the CG180-A Piston offers exceptional tensile strength and heat resistance (up to 380°C). Forging creates a dense, defect-free structure that can withstand the extreme pressure and temperature of 180cc combustion under heavy load—ideal for tricycles hauling 250+ kg or motorcycles used for commercial off-road work.

  • CNC Precision Machining with Heavy-Duty Tolerances – Every CG180-A Piston undergoes rigorous CNC machining, with tolerances within 0.001mm. This ensures a perfect fit with the cylinder bore and Piston ring grooves, eliminating leaks and maintaining consistent compression even under heavy load. Unlike generic pistons that require tedious adjustments, this part is ready for installation out of the box, saving time for mechanics and fleet operators.

  • Wear-Resistant Dual-Layer Skirt Coating – The piston’s skirt features a dual-layer coating: a base layer of nickel-phosphorus for corrosion resistance and a top layer of molybdenum disulfide for low friction. This combination reduces friction between the piston and cylinder wall by up to 42%, minimizes wear, and extends the piston’s lifespan by up to 70% compared to uncoated alternatives—critical for commercial vehicles that log 30,000+ km annually.

  • Reinforced Crown & Wrist Pin Boss – The piston crown is engineered with a thickened, heat-resistant design to handle detonation and extreme heat, while the wrist pin boss features internal ribs and steel inserts for maximum strength.
