I've checked out the site "VisorDown.com" for some time now. They seem to get info on new releases for several models I've followed. I was looking at this article today, and if you look at the 5th picture down, you'll see the front wheel has and ABS sensor, and there's an "ABS" decal on the fender. Maybe the 2016 US model will have this?
