The oil seals in the FSK-019 kit retain fork oil under all riding conditions — from a spirited road run to sustained track use — while the paired dust caps form the first line of defence against the contamination that accelerates fork wear. Using a matched kit from a single manufacturer means both sealing layers work in harmony, which is exactly the kind of detail that separates a properly maintained suspension from one that merely functions.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThis kit fits the Yamaha YZF-R1 for model years 2003 through to 2026. The 43.00 mm inner diameter and 55.00 mm outer diameter match the fork tube specification used across this entire production run. If you are unsure whether your specific build year or fork specification is covered, confirm with an authorised K-Tech service centre before ordering.\u003c\/p\u003e\u003ch2\u003eInstallation Note\u003c\/h2\u003e\u003cp\u003eInstallation should be carried out exclusively by an authorised K-Tech service centre.
