CFMoto Piston Ring Set

OEM Part Number: 0JYA-0400B0

Specs: Groove Heights 1.2 / 1.5 / 2.5 mm | Engine Rebuild Component

Compatible with CFMoto 400cc / 450cc / 500cc / 520cc / 550cc / 600cc / 625cc / 800cc / 850cc / 1000cc models

📋 Product Overview

This product is a genuine CFMoto piston ring set, part number 0JYA-0400B0. Piston rings are critical internal engine components installed in the piston grooves. They are responsible for sealing the combustion chamber, controlling oil consumption, and transferring heat. This set includes three rings, designed to original engine specifications:

1st Ring (Top Compression Ring): Chrome-plated, groove height 1.200mm. Primarily seals against high-temperature, high-pressure combustion gases.
2nd Ring (Second Compression Ring): Taper-faced or twisted type, groove height 1.500mm. Aids in sealing and assists in oil scraping.
3rd Ring (Oil Control Ring): Multi-piece oil ring, groove height 2.500mm. Scrapes excess oil from the cylinder wall to control oil consumption.

Manufactured from high-quality alloy iron with precision processes, these rings offer excellent wear resistance, proper tension, and high-temperature durability, ensuring strong engine power, smooth operation, and low oil consumption.

🔧 Genuine Quality Assurance: Manufactured strictly to CFMoto original technical standards. The ring material, tension, profile, and dimensional tolerances are identical to the OEM part, ensuring a perfect fit with the piston and cylinder to restore engine performance.
