YOSOPP’s gasket caters to GY6 engines commonly found in scooters, ATVs, and go-karts, with a robust copper composition and a double-sided, extra-thick design to reduce exhaust leaks. It targets a wide fit across motors from 50cc to 150cc and emphasizes improved noise control and sealing stability under piston and exhaust system vibrations. The set includes components that align with bolt spacing and mounting hole dimensions typical of GY6 applications.
1PZ MG2-EG5 Exhaust Bolt and Gasket for GY6
The 1PZ MG2-EG5 kit combines an exhaust bolt and gasket, designed for GY6-powered machines ranging from 50cc to 150cc.

This all-in-one option is convenient for riders seeking a single-package solution for gasket and mounting hardware alignment on compatible platforms.
Buying Guide: Key Purchase Considerations and Comparisons
- Engine compatibility: Confirm the gasket’s dimensional fit (32×24.5mm is common for many 50–150cc bikes) and whether your bike’s exhaust port spacing and bolt pattern align with the product specifications.
- Material quality: Copper is a popular choice due to its resilience against vibration and corrosion. Look for multi-layer or extra-thick gaskets if you ride aggressively or face high-heat conditions.
- Pack size and convenience: Larger packs can reduce replacement frequency for riders with multiple bikes or frequent maintenance cycles. Smaller packs are suitable for singles or occasional replacements.
- Brand reliability: Established brands with positive durability claims tend to offer more consistent performance, but verify that the gasket dimensions and copper composition meet your bike’s needs.
- Installation notes: Ensure you have compatible bolts and hardware, and follow proper torque specs to avoid leaks or gasket distortion during reassembly.
- Maintenance frequency: Copper gaskets may require regular inspection in high-vibration environments; consider keeping spare gaskets on hand to minimize downtime after rides or in the field.
- Pricing and value: While price isn’t listed here, compare packs by grams of copper, coating, and batch quality to determine long-term value rather than unit cost alone.
For riders managing retrofits, race-ready builds, or routine replacements, selecting a gasket set that matches both the engine type and the exhaust mounting geometry helps ensure a reliable seal. Copper gaskets deliver solid seal performance under vibration, but always verify exact measurements and compatibility with your model before purchasing.
