I ordered this silencer for what I thought was a 2008 KTM 300 XC. When the silencer arrived it would not fit. After a closer look at my bike, it was found that the top end was 2013. I had bought the bike used and the previous owner had told me this, but in my stupidity, I purchased the silencer for a 2008. I had neglected that my bike is a Frankenstein. Needless to say MotoSport was very helpful and promptly shipped the correct part. This all transpired within a week. I have purchased form MotoSport in the past with great results and will continue... Thanks MotoSport!
