I had mine replaced after about 20000 miles. Went out to start it one morning and it had a puddle under it. Wiped up the oil and went to the dealer. He tried to tell me I had overfilled the bike with oil and the oil was coming out of a tube routed by the shock. I had somebody stand the bike up and the oil was right where it should be. I told them to look an they wouldn't even bend over and look. By the next spring it wouldn't hold air for 20 miles and they finally replaced it. Very bad PR.
