Mirror relocation.

I seem to recall the issue on my 07 and that because of it, I didn't get the same field of view with the round mirrors. I believe that is what prompted me to replace them with Harley mirrors.
 
If your roadster is the same as mine it will have 1/2” difference between each foot peg height to road surface. I got suspicious when I was trying set the bike up as vertical by equalising the dimension.

I have the Roadster footrest assembly on my 06, now I know why I keep snapping off R/H footrests !
