ORAEVY Piston Rings Gasket Set 52.4mm for 110cc/125cc ATV Pit Bike

Description

Product Overview

The ORAEVY Piston Rings Gasket Set is a precision‑engineered component designed for small‑displacement engines with a 52.4mm bore. Each set includes a full complement of high‑strength steel piston rings, a 13mm wrist pin, and durable g‑rings that together form a complete sealing solution for 110cc and 125cc power units. The rings are heat‑treated to provide a balance of hardness and flexibility, allowing them to maintain a tight seal under the high‑temperature and high‑pressure conditions typical of off‑road and racing applications. The gasket material is formulated to resist oil degradation and to retain its shape over thousands of operating cycles, ensuring consistent performance and longevity.

Manufactured by ORAEVY, a brand known for supplying reliable aftermarket parts to the powersports community, this set adheres to the exact specifications required by popular Chinese‑made engines found in models such as Kazuma, Taotao, Sunl, Coolster, Roketa, BMS and SSR. The package dimensions of 5.12 x 3.94 x 3.15 inches and a lightweight 6.74‑ounce build make storage and handling straightforward for both professional mechanics and hobbyist riders.

Usage

Designed for a wide range of applications, the ORAEVY gasket set is ideal for ATV, pit bike, go‑kart, pocket bike and other small‑engine platforms that rely on a 52.4mm cylinder bore. Whether you are rebuilding a high‑performance pit bike for competition, restoring a vintage ATV for trail riding, or upgrading a go‑kart for track days, this set provides the essential sealing components needed to achieve reliable power delivery. The rings fit snugly around the piston, while the wrist pin aligns the piston to the connecting rod, and the g‑rings seal the crankcase to prevent oil leakage.

Installation is straightforward for anyone familiar with basic engine assembly. After removing the old piston assembly, clean the cylinder bore thoroughly to remove any carbon deposits. Install the new rings following the manufacturer’s orientation marks, insert the wrist pin, and secure the g‑rings in their designated grooves. Re‑assemble the engine, torque the head bolts to the recommended specifications, and perform a break‑in procedure to allow the rings to seat properly. The set is also compatible with other ORAEVY accessories such as electric‑start oil seals and clutch components, enabling a comprehensive engine overhaul with a single supplier.

FAQ

What engines are compatible with this gasket set?

The set is designed for any engine with a 52.4mm bore, which includes most 110cc and 125cc Chinese‑made power units found in brands such as Kazuma, Taotao, Sunl, Coolster, Roketa, BMS and SSR.

Do I need additional tools to install the rings?

Standard engine rebuilding tools are sufficient. You will need a ring expander, a piston ring plier, and a torque wrench to correctly install and tighten the head bolts to the manufacturer’s specifications.

How do I break in the new rings after installation?

After assembly, run the engine at moderate RPM (around 5,000 rpm) for the first 10‑15 minutes, allowing the rings to seat gradually. Avoid full‑throttle operation during this period to prevent uneven wear.

Can I use this set on a four‑stroke engine that has been previously modified?

Yes, as long as the cylinder bore remains 52.4mm and the wrist pin diameter is 13mm. Verify that any previous modifications have not altered these critical dimensions before installation.

What warranty does ORAEVY provide for this product?
