Critical Fitment and Return-Prevention Note

Before ordering, match K12121AANNB02S with the old packet, existing kit or Hero EPC/VIN record. Also confirm the motorcycle model, manufacturing year, BS6/OBD generation, engine family, cylinder design, piston specification and gasket arrangement.

This SKU must not be merged with similar-looking Hero cylinder kits such as:

• K12121AANNB00S
• K12121AANNB01S
• K12121AANF410S
• Other Hero Glamour or Super Splendor cylinder-kit revisions

The suffix difference is significant. Similar cylinder kits may differ by piston/cylinder specification, coating, engine revision, emission generation or included components.
