Royal Enfield RLK00121/A – Centre Clutch Assembly (Inner Hub + Pressure Plate) for Himalayan 450 & Guerrilla 450 (Sherpa 450 Engine) – Genuine OEM

Royal Enfield part number RLK00121/A is the genuine Centre Assy Clutch for the new-generation Sherpa 450 engine platform, used on Himalayan 450 and Guerrilla 450 models. Official Royal Enfield partner microfiche portals list RLK00121/A as “CENTER ASSY CLUTCH / ENSEMBLE NOIX-DISQUE H450”, clearly tying this assembly to the H450 clutch system. A recognised Royal Enfield genuine parts dealer further publishes RLK00121/A as “CENTER ASSY CLUTCH – Compatible with: Himalayan 450, Guerrilla 450”, confirming model-level fitment.

This assembly includes the clutch inner hub (“noix”) and mating pressure disc (“disque”), forming the structural core that locates the clutch plates, transmits torque from crankshaft to gearbox and controls engagement feel. Cheap aftermarket hubs can introduce play, notching, vibration and inconsistent take-up – especially on a high-compression, high-revving Sherpa 450 engine. Using the correct OEM RLK00121/A assembly ensures factory-correct spline profile, hardness and machining tolerances, preserving the smooth slip-and-grip behaviour Royal Enfield engineered for off-road and touring use.

Ideal for clutch overhauls, high-mileage Himalayan 450 / Guerrilla 450s, hard off-road usage, or accident repairs, this centre assembly restores stock feel when paired with genuine friction & steel plates and correct clutch spring torque. If your bike shows clutch judder, noisy engagement, or visible grooves on the hub, replacing the centre assembly with RLK00121/A is the right long-term fix.

Only genuine Royal Enfield stock – no substitutes, no guesswork.

FAQs 

Q1. Which bikes does RLK00121/A fit?
RLK00121/A is the genuine centre clutch assembly for the Sherpa 450 platform, used on Royal Enfield Himalayan 450 and Guerrilla 450 only, as per H450 clutch listings and authorised dealer fitment notes.

Q2. Is this a complete clutch kit with plates and springs?
No. This part is the centre assembly (inner hub + pressure disc). You must purchase friction plates, steel plates, clutch basket and springs separately if required.

Q3. Can I use RLK00121/A on my old Himalayan 411 / Scram 411?
No. The LS410 engine uses a different clutch architecture and parts. RLK00121/A is not listed for Himalayan 411 or Scram 411 in any official catalogue checked.

Q4. When should I replace the centre clutch assembly?
If you see deep grooves/notches on the hub splines, experience jerky take-off, harsh engagement, or uneven plate wear, replacing the centre assembly along with new plates is recommended for a smooth, reliable clutch.

Q5. Is this part genuine Royal Enfield or aftermarket?
This listing is for 100% genuine Royal Enfield OEM stock, sourced through authorised channels and matching the part fitted at the factory when the motorcycle was new.
