DOT 5 is not exactly compatible with the stock rubber components of motorcycle braking systems. The seals and o-rings will not break down or deteriorate, but they will drag in the bores of the calipers and cylinders. This in turn leads to the pucks dragging on the discs because the pistons don't retract. If you use DOT 5 the rubber items need to be replaced with a rubber that is designed to work with DOT 5. DOT 5 was touted in all the magazines for its resistance to heat but in practice it caused me nothing but trouble. The big issue with DOT 3 is that it is hygroscopic. Change it out once a year and you're good. Braking a KR will never stress brake fluid nearly as much as road racing a motorcycle and I used DOT 3 in all my endurance race bikes. It was good for an entire season.
