make sure you use decent thickness AL for the dash bracket. Having your dash fall into the wires behind your headlight at speed... not a nice feeling. The AL had vibrated and oscillated with the wind til it failed. stepped up to thicker diamond plate this stuff.
here's the LSL brackets on SBK forks. You can flip it over so the turnsignal mount is on top as well.
I have the 51/53. I had to mount them on the lower part due to the clipons taking the upper 53 space.
But I like the light lower.
