Description
Description
This genuine OEM KTM O-ring (47.00x1.50mm) is a critical sealing component for the cylinder head assembly. It is designed to provide a leak-proof seal for the cylinder head cover or plug, ensuring that engine oil remains contained and internal pressure is maintained. Manufactured from high-quality NBR 70 nitrile rubber, it offers superior resistance to heat and engine fluids.
This part is compatible with a vast range of KTM LC4-engine motorcycles produced between 1994 and 2007. It fits models including the KTM 400 LC4, 620 LC4, 625 SMC/SXC, 640 Adventure, 640 Duke II, 640 LC4 Enduro/Supermoto, and the 660 Rally Factory Replica. It also fits specialized variants like the 450 Rally and 540 SXC models from the late 90s and early 2000s.
Using an authentic spare part ensures a precise fit and reliable performance that aftermarket seals often cannot match. Replacing this O-ring during routine top-end maintenance or whenever the cylinder head is serviced is highly recommended to prevent oil seepage and maintain engine cleanliness. The durable NBR 70 material is specifically chosen for its longevity in high-temperature environments.
