Get the Hero Genuine Chain Sprocket Kit (Chain Kit / Sprocket Set) for Hero Karizma ZMR – Part No. 20K600S. This OEM kit restores correct final-drive meshing for smoother pickup, reduced chain noise, and longer service life versus local duplicates. Supplied as a genuine packed unit for safe, accurate fitment.

DETAILED DESCRIPTION 

The Hero Genuine Chain Sprocket Kit – 20K600S is the complete final-drive replacement set for the Hero Karizma ZMR series. In the market and at workshops, it’s commonly asked as “chain kit / chain sprocket set / chain gear set / chain-chakkar set”—and it should be replaced when you notice chain stretch, hooked sprocket teeth, frequent slack changes, vibration, or a jerky feel under throttle.

Choosing an OEM Hero kit is important because final drive parts are tolerance-sensitive: sprocket tooth profile, pitch matching, and material treatment directly impact power transfer and wear. The official Hero listing highlights a high-carbon steel/heat-treated build intent for reliable transmission and durability, while also emphasising noise/vibration control.

For 20K600S, reliable genuine-parts sources map this part number to Karizma ZMR (including specific model-year entries like Sep 2009 / Mar 2011 / Jul 2012). Another established seller lists it under the Karizma family and provides kit specifications (3-part kit; sprocket dimensions).

At underthehood.co.in, we focus on genuine packaging and correct part-number dispatch, which is critical for chain kits where fake/local kits are common and failures can be costly.

Trusted fitment listings map it to Karizma ZMR (e.g., Sep 2009 / Mar 2011 / Jul 2012 entries).
