Besides just changing a bad seal, hopefully you can determine what went bad and why. A outer wiper damaged can allow crud up there to eventually cause a seal to fail, i had that happen to one of my bikes, not that brand though, but that could happen with anyone. Being able to see what /why would help prevent it in the future.
electric adventures , my previous post was more for jojotide asking why do you think you need maintenance, i should have been more specific in my reply.
