Fitment Note / Return Prevention Note

Before ordering, match K12121ABWC201S with the original packet, existing cylinder kit, Hero EPC or VIN record. Confirm the motorcycle model, manufacturing year, 4-valve engine generation, BS6/OBD version, cylinder number, piston specification and gasket layout.

Do not confuse this SKU with:

• K12121ABWC200S – listed as a cylinder-head kit, not this cylinder kit
• Xpulse 200 2V cylinder kits
• Other K12121-series Hero cylinder kits
• Aftermarket big-bore or performance kits

This is a standard genuine replacement kit. It is not a performance big-bore conversion and should not be used to increase engine capacity.

Technical Details

Installation Note

Professional engine installation is strongly recommended. Before assembly, inspect the cylinder head, valves, camshaft and rocker mechanism, 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, timing marks, tightening sequence, torque values and valve clearance before starting the engine. Do not operate the motorcycle until compression, oil circulation and engine timing have been verified.

Buyer-Focused FAQs

Q1. What is Hero part number K12121ABWC201S?
It is a Hero Genuine standard cylinder kit for selected Xpulse 200 4V, Xpulse 200T 4V and Xtreme 200S BS6 OBD-II applications.

Yes, it is confirmed for listed Xpulse 200 4V applications including October 2021, July 2022, April 2023 OBD-II and November 2023 EU4 references.

Q3. Does it fit the older Xpulse 200 2V?
No 2-valve compatibility is being claimed. The 2V engine uses different cylinder and piston components.

Q4. Does it fit Xpulse 200T?
It is confirmed for selected Xpulse 200T 4V FI and OBD-II applications. It should not be assumed for older 2V versions.

Q5. What parts are included?
The catalogue lists the cylinder, cylinder gasket, cylinder-head gasket, head-cover gasket, standard piston-ring set, piston, piston pin and two piston-pin clips.

Q6. Is this a big-bore performance kit?
No. This is a genuine standard replacement cylinder kit, not an engine-capacity upgrade.

Q7. Is K12121ABWC200S the same part?
No. K12121ABWC200S is a different kit description and must not be treated as interchangeable with K12121ABWC201S.

Q8. Should a mechanic install it?
Yes. Cylinder-kit replacement requires accurate measurements, engine timing, torque control, lubrication and post-assembly checks.
