I to was wondering why they would not have this as a factory option...but I know there are a few guys on here that have some aftermarket set ups and these work well from what I'm hearing. I will differ to them to answer this a little more in detail. I know its not factory but in my opinion there is so much about this bike that is great that the few things that it doesn't include I can overcome really easily. I hope that you give it a proper shot and test ride it and then go from there....I think you will be really impressed.
