If you have an FJR with a Givi rack and box, you may want to be very careful about how much you load it and what sort of valuables you put in it. I used the rack to mount my auxiliary fuel tank. The tank held almost ten liters which, at about 1.5 pounds / liter, totals about 15 pounds.

I believe the rack capacity is 11 pounds. I think engineers generally consider the working load to be 50% of breaking load. So, while I was overloaded, I would not think that 4 pounds is that much for the size of steel tubing used for the rack. The rack finally failed at some point riding through a construction zone. Not terribly bad and typical of what most riders expect to experience a few times each year.

In looking at the breaks, I noted the following:

• Rust has formed on both sides. That tells me that they both cracked some time ago.
• You can also see that the tubing appears to have snapped. I would have expected something more like the sort of bending normally required to break a piece of normal tubing.
• Both breaks occurred right behind the welded on cross brace. I'm no metallurgist but my guess is that the welding tempered the tubing and it became quite brittle.
