I would think there would be a decent amount of used ones out there with the change of style. I know I have one but I think one of my buddies is buying it (it's the older one with the metal back plate and the original hardware). Check around, see if you can find a cheap used one. If not, personally it was the last of many shields that I put on my bike and I was happy with it. Having said that, I'm not sure that I could convince myself to put one on the 2017. I have zero issues with the '17 anyway in regards to buffeting etc
