Fitment Note / Return Prevention Note

Before ordering, match K12121AANNB00S with the original Hero packet, existing cylinder-kit number, Hero EPC or VIN record. Confirm the motorcycle model, manufacturing month, BS6 generation, cylinder design, piston specification and gasket arrangement.

Do not order only by the words “Hero Glamour” or by engine capacity. Glamour motorcycles have used several different engines and cylinder-kit revisions.

Do not automatically use this kit for older Glamour BS4 models. Some third-party listings describe this SKU as BS4, while the stronger exact-SKU application record maps it to the 2021–2022 Glamour BS6/XTEC range. Confirm through the Hero EPC before dispatch.

• K12121AANNB02S
• K12121AANF410S

The final suffix is significant. Similar-looking kits can differ by engine generation, cylinder casting, piston specification, emission version, oil passages or gasket combination.

Installation Note

Professional engine installation is strongly recommended. Before assembly, inspect the cylinder head, valves, connecting rod, crankshaft play, oil pump, cam chain, guides, tensioner, cylinder studs, mating surfaces and lubrication system.

Confirm piston orientation, ring end gaps, cylinder lubrication, engine timing, tightening sequence, torque values and valve clearance before starting the motorcycle. Do not operate the engine until compression, timing and oil circulation have been verified.
