All I know is that my daughter went around my truck and tried coming up on the pavement at to shallow of an angle and she went down at low speed and this is what I found out the next day... these bars don't have a brace that keeps them from bending back. She wasn't hurt and they did their job as her leg was fine and the bike was protected. That's why I bought them. Leg protection on a spill over. She only has the GIVI 22's.
Another thing you NEED to know. They are stainless steel u-bolts and a stainless cap nut. You need to lube these or else they will gall when you try to take them off and the nut won't come off and it will snap. Trust me I know! You will need to take the right side U-bolt off when you do your valve checks. Otherwise the plastic threaded plug on the engine block can't unscrew enough to remove. I now have steel u-bolts and they are lubed with anti-seize. Bought at Fastenal and the bolt length cut to correct length with a hacksaw and the nut at the right length so the threads don't get messed up. The other bike has stainless and I lubed that with anti-seize and no problems. Learned on the first bike.
