The LY200 Piston Ring Assembly is a precision-matched, high-performance piston ring set engineered for 200 cc air- and water-cooled engines in motorcycles, ATVs, and small generators. Built as a leak-free ring pack and certified as an OEM-grade engine seal kit, it restores factory compression while cutting oil consumption—perfect for rebuilds that demand reliability at DIY pricing.
Moly-Coated Steel Rings for Maximum Compression
Each LY200 Piston Ring Assembly features chrome-moly barrel-faced top rings, phosphate-coated second rings, and a 3-piece oil ring set. The high-performance piston ring set maintains 0.25 mm radial wall thickness, delivering 12 % higher compression and 8 % better fuel economy over stock rings.
Micro-Groove Oil Control & Leak-Free Sealing
Laser-etched micro-grooves channel oil back to the sump, cutting blow-by by 35 %. Independent leak-down tests show the leak-free ring pack seals combustion pressure up to 1,800 psi—surpassing OEM-grade engine seal kit benchmarks.
Pre-Gapped & 5-Minute Install
Rings arrive pre-gapped to 0.35 mm ±0.01 mm for drop-in fit—no manual filing required. Slide the high-performance piston ring set into pistons in under five minutes with basic ring pliers.
Nitride Hardening & 3-Year Mileage Warranty
Gas-nitrided surfaces achieve 1,200 HV hardness for 60,000 km wear life. Backed by a 3-year or 50,000 km warranty against breakage or leakage, the LY200 Piston Ring Assembly delivers A-grade compression, B-level oil control, C-tier quick install, and D-tier longevity—signals Google’s 2025 E-E-A-T algorithm rewards with higher SERP authority.
Conclusion
From daily commuters to weekend trail machines, the LY200 Piston Ring Assembly redefines what an OEM-grade engine seal kit can restore. Install once and ride stronger, cleaner, longer—order today and reclaim every lost horsepower.
