Hero Genuine Chain Sprocket Kit (Chain Sprocket Set) for HF Deluxe, Splendor+ & Passion Pro – Part No. 20K1110S

Replace your worn chain-sprocket the OEM way with the Hero Genuine Chain Sprocket Kit – 20K1110S. Officially sold by Hero as a genuine kit for HF / Passion / Splendor platforms, this set restores smooth power delivery and reduces noise/jerks—ideal for commuters who want correct fitment over local “chain kit” copies.

DETAILED DESCRIPTION

The Hero Genuine 20K1110S is a complete Chain Sprocket Kit (commonly asked as chain sprocket set, chain kit, chain gear set, or chain-sprocket jodi). This kit is designed to renew the drivetrain—helping your motorcycle maintain clean pickup, reduce chain slap noise, and improve overall riding smoothness versus running a stretched chain on hooked sprockets.

Hero’s official listing describes this as a genuine kit made from CRC high carbon steel, with sprockets that are heat treated and hand finished to support strong power transfer and durability—important for daily Indian road use where dust and water accelerate wear.
For the market, this is one of the highest-intent maintenance replacements because most riders search by part number (“20K1110S chain sprocket”) once a mechanic recommends replacement.

Verified fitment signals: Hero’s official store positions 20K1110S for the HF / Passion / Splendor series, and multiple established spares sellers list applications including HF Deluxe / HF Dawn, Splendor+ / Splendor iSmart, and Passion Pro (variant-wise).
Because chain-sprocket ratios can vary by variant/year, confirm compatibility on the Hero portal/ASC using your exact model/variant before ordering.

At underthehood.co.in, we ship properly packed genuine parts to help you avoid counterfeit “chain kits” and transit damage.
