I think the C and my Sport 1100i have the same "upside down" forks. I had a seal leak a couple of years ago (75K miles) and bought a pair of seals. I changed the one that leaked, and it was a major PITA. the other new seal is still on the neck of the fork oil bottle, on the shelf, to be dealt with only if and when necessary. I don't have special tools, and it was hard for me to get that new seal in without damaging it. Your mileage may vary.
