Technical Specifications & Details
Component: Piston Kit (Piston & Rings).
Material: High-grade aluminum alloy and specialized steel rings.
Compatibility: Shineray XY250STXE, Bashan BS200/250, and other 200-250cc Chinese ATVs.
Benefit: Precision manufactured for reduced friction and improved engine response.
Visual Compatibility: Before installation, perform a visual check. Measure the piston diameter and pin position carefully to match your original parts.
Ring Orientation: Ensure the "TOP" mark on the rings faces the piston crown. Stagger the ring gaps (approx. 120° apart) to prevent blow-by.
Direction: Check the mark on the piston crown (Arrow or "IN"). Usually, the arrow points to the exhaust, while "IN" points to the intake.
Break-in Period: A new piston requires a break-in period of 200–500 km. Avoid high RPMs and full throttle during this stage
