Valve Stem Seal (Seal-Valve Stem) for Royal Enfield Himalayan 410 Euro 4 / Himalayan 411 | 574147/A | Genuine OEM

Royal Enfield 574147/A is the genuine Valve Stem Seal (listed in OEM catalogues as SEAL-VALVE STEM). It sits on the valve guide and helps control engine oil at the top end—preventing oil from getting pulled into the combustion chamber while still allowing proper valve stem lubrication. 

If you are seeing blue smoke on start-up, oil consumption, fouled spark plug, or oily deposits around the intake/exhaust ports during a cylinder-head job, worn valve stem seals are one of the first high-value replacements (especially when the head is already open). This OEM seal is the correct spec used by Royal Enfield at the factory and is priced as a low-cost preventive part compared to repeat teardown.

Official parts assignment shows this seal mapped to the Himalayan 410 Euro 4 / Himalayan 411 cylinder head application. 
For reference in India trade pricing lists, 574147/A = Valve Stem Seal is also shown with MRP ₹55 (HSN 40169330, GST 18%)—helpful for valuation and procurement checks.
