Nice. i use double h pads with hel braided hose lines may look into the bremb conversion all the same. i think the nissin are great brakes though.
then you probably never used anything better? It's a sliding caliper with 11mm master and 27/30 slave pistons. Weak from start then add near 20 years of wear... The brembo is 13mm and 30/34 on a fixed 4 pot so the numbers are better plus there is the bling factor! You will easily stoppy the bike if you want to :-)
You would have to do a small amount of rewiring to fit the switch up (easy) and I had to melt a recess into the rhs switch gear for the lever to fit, easy with a plumber's soldering iron.
