I ride a 2006 Sportster and a 2010 Road King. I made a bucket that clamps to the left side passenger footpeg, I have an old In Stroke 3x7 that slides into the bucket, and is then bungie corded to the saddlebag. The case stands up behind my left shoulder. The bucket is about 24 inches deep, and the case fits snug, Its mounted to the foot peg with 2 hose clamps. It works for around town, haven't tried it on along trip yet, but the plan is to take the bike on one of the Mezz WestState Tour events, but to do that I need to get the Road King off the left and back on the road.
