I know Honda, Kawasaki, Suzuki & Yamaha has been using it as far back the 80's but many bikes from 70/80/90/00's etc was label as DOT-3 or 4 on master cylinder reservoir lid

Keep in mind DannoXYZ it has to be readily available in are local auto parts store this is generally where 95% of the people go instead of a reg motorcycle shop and shop here in Oklahoma don't carry Super DOT 4+

I have seen DOT-5 system that been more then 15 year old and never ever had their brake fluid changes unlike DOT-3/4 especially in bikes, cars and trucks from the 70s, 80s and 90s even few case from 2000 it looked like coarse sand inside the reservoir after sitting for more 10 years what really surprise me it that both of my 05 and 07 Ninja 250 req DOT-4 and don't like they have ever been open up.
