For what its worth.......
I had the misfortune of laying the bike down 2 weekends ago, on the first 60 degree day we had. My wife and I escaped injury, FJR......not so much
Its sitting at the dealer right now after the insurance agreed to repair it, waiting for parts.
The canyon cages and the sliders I attached did their part quite well on the original Low Side, when we hit some leftover oil/debris on a turn, however after the original Low Side, the tires caught traction again, and the bike stood back up and High Sided.
That threw me and my wife through the air, and this time the FJR landed hard enough to go past the tipping point that the canyon Cages and sliders provide, destroying the side mirror and right side of the upper fairing.
The left side (the original "first contact" side) looks perfect, other than a worn slider. Were it not for the tires catching traction again, a continuing slide would have just resulted in a worn slider. So.....the Cages and sliders did their job......up to a point.
The M12 bolts held, but the one on the left side (the High Side side) did bend.
