I've ridden 8000 miles with a Pelican 1520 case bolted to my stock rear plastic rack and no signs of breakage. However, it's a b-i-t floppy and since I added BR Moto side racks I fabricated an extra support to beef things up. I initially tried some 1/2 aluminium l bracket, but decided to go with 1/2" square tubing. First trick was cutting some reliefs to make some 45 degree bends. Last time I checked 22 1/2 x 2 = 45. Angle grinder action (yeah, I staged this for the picture....I couldn't operate the camera and make sparks at the same time). A little gentle tweaking and I had some nice 90 degree bend joints read to be welded. A little help from a work colleague with a MIG welder. A few bore holes for bolts and time to dry fit. At this point I tried pushing down on the rack and can tell it's exactly what the doctor ordered! A side view shows how it ties in with the BR Moto rack. A little rattle can action later. And mounted up with the Pelican reinstalled....it's the right amount of extra beef with just a little added weight. No way I'm going to have this happen now.
Nice job. I had thought about getting the BR Moto rear rack but I quite like this and could make it myself! How did you bolt on the Pelican?
8000 miles is nice to know. I've been a little reluctant in mounting my top case. I've only seen one post with a broken rack. Has this happened to anyone else?
