I found on my SPS that I had to have longer bars because they fouled the clocks which is an mot failure.

The brackets are . . .
 

bought - off the shelf - they are Motrax mirror bar-end mirror mounts that fit on the ends of the handlebars (I have long bars) I only used the bracket and the tapered internal bar mount - I then butchered the actual mirror mount - added a carbon rod - a titanium bolt etc and hey presto!

Radial master cylinder
 

Just ordered some after market brembo master cylinders myself. Can you use the original brackets with the new cylinders ?
