Tork, that is not really true. The dealer cannot force you to have all periodic maintenance done by them to keep the warranty valid. The warranty is good as long as all the maintenance is done, even in your garage, as long as you have receipts as proof. I have been keeping a maintenance log on mine.

I have an exhaust and an EBR ecm in my bike that will void the warranty if the dealer doesn't want to honor it but it is the dealer's discretion. Fortunately, I have a good dealer.
