I heard a clunk and the speedo/odometer quit working. I took it to the dealer and was told the output shaft is broken. Damage is extensive, I was quoted a price of at least $4000. I have done some digging, and found at least 3 other cases with the same bike. Needless to say, not happy. I am in contact with Yamaha to try and sort this out, as it is not under warranty. 其他人有同样的问题,或有什么建议吗?
