The Stock Master Brake Cylinder on a CX500 is at a steep angle because of the pull back stock bars. So, when I put standard handlebars on my bike, I put on a 1985 Nighthawk master on it. I am happy with my modifications so far. Harley mufflers 30 , china mirrors 15 , Nighthawk master 30, Handlebars 22, battery 30, plastic dip 14, speedo gear 15, needs tires yet. UPDATE 10/14/2014 The Night hawk master was made for two 2 piston calipers and shoved a boat load of fluid to my one piston one caliper brake. I would use 1/3 pull and it would be full stop. So, I went back to my DR350SE Master Cylinder, yes, it takes all the room to lock it up, but that is better for me than too much brake too fast.
