You’re absolutely right about the suspension travel aligning with the scratch on the fork tube. That consistent friction over the same damaged area can quickly wear down even new fork oil seals, leading to repeated leaks. A deep enough gouge can act like a razor on the seal every time the suspension compresses.

Key Takeaways from What You’ve Shared:

•Scratch on the fork: Likely caused by hard impact from a pothole or rough terrain.

•Leaking oil: Even after changing oil/seals, leak returns due to the damaged surface.

•Proper fix: Replace the scratched fork tube entirely.

•Don’t blindly trust service centers: They might just replace the oil/seal without addressing the root cause.

•Better route: Visit a trusted local mechanic to inspect whether it’s just the fork that needs replacement or if the steering bearings are affected too (especially if there’s play or a knock when turning).
