OK I checked out the link and realized I was barking up the wrong tree. These are not new, larger floorboards. These are kits that allow you to reposition your existing boards. Is that what all these kits we're talking about do?
Yes, they extend the boards outwards from the bike by 3/4". There's also 1' kits available too.
Does anyone have floor board extensions on their tourer? I always find the placement of my feet is half on the board and half off because of how close the boards are to the frame. Obviously with extensions you'll scrap more but if anyone has them I wanted to get some opinions on whether you'd buy them again or not. They are cheap about $40 bucks (8 beers) so either way can't be too bad of an investment.
