Me too!....check my avatar photo. I ride a 2015 BMW GS1200. It weighs about 550. Plus me on top and all the junk I usually carry, say a total of 750 pounds. Man! I'd hate to put a kink in that ramp. Cool as it is, if that thing got bent, heck, it'll never retract again. Yeah. I'm a bit worried. With the quad, it seems the weight would be spread out. Any other thoughts from bikers out there?I'm looking forward to the easy load tailgate to get m motorcycle in and out of the bed.
