This came up on the ST forum not so long ago and I will repeat it here because I was looking at the fluid in both the window on the handlebar and the resevoir under the seat as a matter of course. Have never seen the brake fluid any color than a light yellow. So I ask again what color should it be? I remember that my ST had different color fluids in the brake and clutch windows from day one and no one could ever explain that since they were supposed to be the same.
