Dot 5 will eat through rubber parts pretty quickly unless you find freindly replacement parts to use in the master cyl and wheel cylinders, etc. Thats why they say dot 3 only. Ive heard of people using it for a few years before all the rubbers gone and the brake parts all fail.
In my experience most motorcycles are meant to run on dot 5. If you can find a source for dot 5 rubber parts, please let us know where.
