Exhaust Gasket for 50cc GY6 and Minarelli Scooters
This exhaust gasket creates a tight seal where the exhaust meets your scooter, so exhaust gas stays inside the system. It is a dependable replacement for several models, among them the Bella Classic 50, Nitro Sport 50, and Pug 50. As one of the GY6 50cc scooter parts, it helps the exhaust system stay secure and working as intended.
Replacing a Worn Gasket
Heat and pressure gradually wear down exhaust gaskets, leaving them cracked or damaged. This gasket works as a direct replacement and brings the exhaust connection back to a sound condition. A snug seal keeps gases where they belong and supports smoother engine running.
Construction and Measurements
The gasket is a ring type, with a 25.25mm inner diameter, a 32.25mm outer diameter, and a thickness of 4mm. Its small round profile is made to sit correctly in the matching exhaust seat. If your components have been altered in any way, check these measurements against your current gasket before you buy.
