Hero Genuine Chain Sprocket Kit for Splendor+ (Y2K) – Part No. 20K211S

Buy the Hero Genuine Chain Sprocket Kit – 20K211S, officially positioned for Splendor+. This OEM chain kit / chain sprocket set restores smooth pickup, reduces chain noise, and ensures correct tooth ratio fitment with genuine components—ideal when your chain is stretched or sprockets are hooked. 

The Hero Genuine 20K211S Chain Sprocket Kit is a complete drivetrain replacement kit for Hero Splendor+, commonly searched as chain kit, chain sprocket set, chain gear set, or chain-sprocket jodi. When a bike starts feeling jerky in low gears, makes rattling noise from the left side, or the chain needs frequent tightening, the usual root cause is a worn chain and sprockets. Replacing the full set together is the correct fix because mixing old and new parts reduces life and can create noise and uneven wear.

Hero’s official description confirms the kit contains Final Driven Sprocket (43T), Drive Sprocket (14T), and Chain Drive—so your mechanic can verify the tooth count before installation.
Hero also states the kit is made from CRC high carbon steel, with sprockets that are heat treated and hand finished to meet OEM performance expectations.

Fitment accuracy (important): Hero’s official product title positions 20K211S for Splendor Plus, and established parts sellers also list it specifically for Splendor+ variants (with model-month references).
If your bike is HF Deluxe, do not order this by assumption—HF Deluxe commonly maps to a different kit such as 20K1110S (Hero positions that kit for HF/Passion/Splendor families, subject to catalogue check).

We ship genuine parts with careful packaging to reduce transit damage and help you avoid local/counterfeit “chain sets”.
