An open-ended ring that fits into a groove on the outer diameter of the piston. Its chief function is to form a tight seal between the piston and cylinder wall.
Most motor bike engine pistons have up to four rings: two for compression sealing, two for oil sealing. The rings displayed here will fit most Chinese and Japanese engines depending on bore and stroke. Some mechanical knowledge is required to replace piston rings.
Always refer to engine manual. If its not available, contact your local licensed mechanic.
To find out what piston rings size that you need, you can always refer to the engine number. Engine number usually starts with "1" or "1P", then follows by 52FMI, 63FMM, etc. Here 52 and 63 means piston size. Now you know what size piston rings you need.
