Damn it I'm on the record as not liking these things as at high speed (let's say above 120mph) if the nose came up unexpectedly from a dip in the road or a wind gust or just twitchy response right when you are wrapping it open, they could suddenly catch air in a way that would be unexpected. Which is why I call most winglets bike flippers. I also agree that above a certain speed (let's call it 40 mph) they do have a lot of potential to damage the frame.
But at lower speed, abs can't help you if you hit invisible oil on the road right when you hit your brakes. I worry about that because let's say you are in dense traffic on a freeway following a car whose brake lights suddenly slam on when you happen to be directly behind him and you hit invisible oil on the road just when you slam on yours. (I dumped my FJ 1100 doing that). These things might indeed save you some expensive plastic. And I want to hate them but they are lower and wider than conventional winglets which gives them kind of a cool look.
And as the angle is adjustable, I'm kind of curious how much fun it would be to take them out on an empty stretch of road and do some high-speed runs playing with different angles and seeing whether you can feel the downforce or not. I find wings on cars really counterintuitive. Most of them are fixed so they can either reduce drag going straight (which does make sense to me) or produce downforce on fast curves, which I have a hard time seeing. *They also can have vertical components on the ends of the wing which these things do, and that can provide additional stability at speed. I'm not sure the Hayabusa needs that but maybe mine could use it. I may be the only guy on the Forum with raising links...
