I going to change the brake fluid on the R/3 shortly during my next maintenance interval. I see the book calls for DOT 4. It seems every bike I have ever owned with disk brakes calls for a different DOT fluid number. I know that DOT 3, 4, and 5.1 are glycol based and hygroscopic (wick water from the air) but what is the real difference between the ratings?
