Hey guys - I bought the 2" Rox 'pivoting' riser. I was most interested in bringing the bars back towards me as opposed to raising them higher. I ended up with a combination of mostly back along with some up height. I got the bars where I wanted them and then I moved the brake cylinder to the left by about a half inch to relieve the throttle cable strain. It doesn't effect my ability to grab the brake. I still had some concern about the tightness of the throttle cables, so, I took the bike to my local Honda dealer and the service guy told me that I was good lock to lock, but that I should not go any further.
The related issue is, of course, the relocation of the gauge console to accommodate the riser. I solved this problem by purchasing another factory gauge console bracket ($15) and connecting the two of them with a piece of eighth inch by 1 3/4" aluminum cut to the right width. It took me a long time to get the angles right. Using the second factory bracket helped me a lot because it allowed me keep the frame attachment holes exact as well as the three cushioned connection points to the gauge console. So, I only had to worry about the angles, which were a lot of trial and error. My tools were a Sawzall, vice, hammer and bench grinder. Note that you also have to be careful about how far you can stretch the cable going to the gauge. As the cable comes down from the gauge console, it Y's left and right and the two sides are clamped to the frame. I had to remove these clamps to make the whole thing work. Without the clamps, there is the potential for abrasion where the cables could rub against the headlight cover. I zip-tied the two branches of the Y together, but not too tightly. This seems to have solved the problem. I've been watching this and so far I've seen to issues.
After you get the bracket right, there is a lot of cable ugliness visible between the gauge console and the headlight cover. Thankfully, my dark tint windshield covers this up. I also achieved a better viewing angle than the original. My bracket is not something I would proudly show off to an engineer/machinist, but it is very stable with no vibration transmitting up to the console and it's essentially invisible. I'll post some pics when I get the forum's picture posting permission.
