Its worth noting that my need for this mod comes from the perpective of a 6'4" frame and a size 12 boot. The floorboards on my 2010 SEUC are simply to close to the bike and too far back to be comfortable. They had to be moved but I wanted the relo to look complimentary to all the chrome on the floorboards of an SE bike.
I looked at various options and I could only find one that moved the boards outwards 1" AND forward 1" AND would be compatible with my lower fairings AND were available in chrome to compliment the bike.
I just finished the install and I have to say I'm very pleased with the improvement, the look and the overall design. I installed Kuryakyn's chrome floorboard relocators part #4588 - $79. I can tell you these are a perfect fit for the 2010 SEUC and are designed for most other HD Touring models.
Takes an hr or so to install only because the chrome plating makes the allen wrenchs a tight fit on the chrome shoulder bolts. You'll need to work with the bolts and your allen wrench before trying to install. Start by forcing the allens into their socket past the thicker chrome plating before starting the install. After a few dry fits you'll be ready for the install and the allens will go in smoothly. The kit comes with a few chrome washers but I found I needed a couple more than they included in the kit to ensure a nice snug fit. Not critical if you don't have them but I found using a couple more SS washers made for a rattle free assembly.
The feeling of the extra floorboard space is actually a relief and makes placement of your boots for braking, toe shifting and heel shifting sooooo much better. This mod is a no brainer for anyone seeking more use of their floorboards and a more comfortable ride. Here's a few after shots of the install.
Left FB from above...note the board is now forward, outward and slightly into the lower fairing (no rubbing whatsoever on the fairing).
