So I just wanted to share my experience, since parts availability is always a concern. I cracked the rear (underseat) plastics in a garage mishap, sending me into a panic about finding a replacement part. Prior experience with Victory dealer pretty much ruled them out. On a hunch, I googled for Victory Empulse TT parts fiche, and what do you know, you can order directly from the Polaris website! I've never seen that before from an OEM (usually you either have to go through dealer, or third parties like BikeBandit):

Ordered on the 26th, had some questions so called up and was able to talk to a human pretty easily, shipped on the 29th and arrived yesterday. All in all, a pretty pleasant experience!
I know some people are down on Polaris, for a host of good reasons, but at least our bike is not a full fledged orphan when it comes to parts....which is nice!
