Specification

OEM:	LF479Q2-1004012A
Model:	Lifan X50
CYL:	4
Bore:	78.7mm
Pin:	20*57
Size:	0.00—1.00 mm

Thin-walled skirt design reduces weight by ‌15%-20%‌, minimizing reciprocating inertia for enhanced engine responsiveness.
Offset piston pin (0.5-1.5mm) significantly lowers lateral impact and NVH (Noise, Vibration, Harshness).
Combined with lightweight design, proven fuel savings reach ‌5%-8%‌.
Skirt graphite coating 30% less cold-start wear .
‌Endurance Test‌: ‌500-hour‌ full-load dyno operation, deformation <0.03mm9.
‌Precision Control‌: Diameter tolerance ±0.01mm, pin bore; roundness ≤0.002mm.
‌Material Certification‌: Hardness HB 90-120, thermal expansion coefficient ≤21×10-6/℃ (20-200°C).
