DOT 5.0 is the silicone-based stuff and can't be mixed with the others without proper flushing of the system first.

Yup, you get the ceegar! Says right here that you can put dot 5 in a 3/4 system with proper flushing of the system.
There are advantages to dot 5. For those intrested in conversion, read up on the term 'proper flushing' before trying this at home. It also appears KTM has changed the brake fluid spec. sometime after 2000. Thanks guys.
