DOT 5 fluid isn't used in very many vehicles, with HD being one of the few. That explains why some non-HD-savvy people say not to use it. I've even been questioned by newer employees when buying it in auto parts stores. A few more seasoned employees have asked what kind of Harley I have when I buy it.
FYI, over time it changes from purple to yellow, so don't assume the fluid in the bike is something different if it's yellow. That had me a bit concerned the first time I did a flush.

DOT 5 is the most stable brake fluid you can buy because it is silicone. I finally flushed my rear brake system at 12 years old (2 years ago.)
I'll get around to the front when I replace my front brake lines. ( The plastic coating is yellowing a bit.)

I've only used American Grease Stick silicone brake fluid, which is purple. I guess there are other brands that are different colors when new.
