Well the manual says 15000k miles is time to replace the brake fluid. Me, I am not 100% certain I really need to do this. Maybe I do! I mean I have owned cars and put tens of thousands of miles on them without doing this. I realize a bike is not a car but I kind of think brake fluid is...., well I wonder how others feel about this. I mean, after reading that magnificent sticky about stators, this is the place for answers.
