I know this has been covered before, but thought I would add my results. I recently bought this C14 used, 2008. It came with 2' risers. I've been fooling with trying to get the seating comfortable, and thought to try the ergonomics without the risers. I was able to purchase the correct length 8mm allen bolts at the local ACE hardware. I am very satisfied with the results. The entire feel of the motorcycle has improved. It feels 50lb lighter, handles more to my liking, is more comfortable, and actually makes the seat I am now using feel more acceptable. I admit to not taking a 500 mile trip with this set up, but will soon do so. For the record, I am a bit tall, a few inches over six feet. I am also coming off of a VFR800. The position I now have on my Concours is a bit less extreme than the VFR, but very comfortable. I also pondered taking the 2" risers and cutting a couple of custom lengths on the band saw, say .5" and 1", to try if I get the urge. I know it won't suit everyone, but if you have not tried your C14 without risers it is an easy experiment to try .
