Stock brakes suck. There, I've said it ...

Big improvement after replacing the stock pads with EBC green sintered shoes, but ...

Any other calipers fit?

PS - I cooked the stock brakes on my Yamaha Royal Star first time thru the Tail of the Dragon. Replaced those with R6 calipers and a Honda VTX master cylinder capable of juicing them bad boys up. Night and day difference - bulletproof no matter how hard I was on em. So ... hopefully some closet mechanic has come up with something. I'm assUming something built to deal with a lot more weight.
