Hero Genuine Piston O/S 0.25 for Glamour & Super Splendor | Oversize Piston / Engine Piston 0.25 | 13102KTC305S

Product Description

Restore compression, piston-to-cylinder fit, and engine efficiency during rebuild work with the genuine Hero PISTON O/S (.25), part number 13102KTC305S. Hero’s official store lists this exact SKU for Glamour and Super Splendor and describes it as a precision-built oversize piston designed to maintain tight tolerances, reduce wear, and improve combustion performance.

This is the right replacement when the cylinder has been rebored for a 0.25 mm oversize piston and the old piston is worn, scored, noisy, or no longer holding proper compression. A genuine oversize piston matters because skirt profile, crown dimensions, material quality, and machining tolerances directly affect oil control, combustion consistency, and engine life.

This listing is intentionally customer-focused and conservative for return prevention. The strongest official fitment is Hero Glamour and Hero Super Splendor.
