What You Need to Know If You Want To Choose The Best Brake Fluid For Your Motorcycle

There are a lot of different types of brake fluids out there, which one is the best brake fluid to put into your motorcycle?
Well if it’s for general commuting, i guess it doesn’t really matter that much as long as the fluid doesn’t have water in it.
But for sport and track riding, and extreme conditions [both hot and cold] it’s a different story.
This video is about what we learned when we looked to answer that question - what is the best brake fluid to put into our BMW S1000RR race bike, especially now that we had fitted the Beringer Thumb Brake on the rear and anticipated generating much more heat in the rear brake system.

brake fluids naturally grab water from the air, regardless if you're near water or not. it just degrades faster on more humid environments/places.

[@TheBikeStig]

thats true, cheers

[@Krikstar123]

Best explanation of DOT fluids I've seen so far👍

[@TheBikeStig]

cheers mate, thanks for the comment

[@ndvsss1]

Very insightful. Thanks for sharing the knowledge

[@TheBikeStig]

hey cheers mate, yeah I do wonder if my little ventures down these rabbit holes is useful to anyone else.

[@Ratty_Suzuki_GSX-R750]

Very insightful video. Seen this just in time, as I need new fluid for my bike. 🙌🏽

[@TheBikeStig]

cheers mate, I saved you going down the rabbit hole lol

[@ryanmuhtadi]

Thank you for this. Cheers from Indonesia.

cheers mate

I went thru this exercise recently when I upgraded the master cylinder on my K67 to a Brembo RCS19 Corsa Corta and came to the same conclusion. Ended up using Motul RBF700. I actually bought it from the same Italian supplier which supplied the MC and it was only A$18 per bottle so I bought a few. Costs about 3 times as much here in Oz.

[@TheBikeStig]

It is an interesting exercise thats for sure. Cleared up a few misunderstandings on my part. Yeah the 700 is expensive over here.

[@SteveMuir]

I bought some 660 a while back and it was 3 times the price of the Repco DOT $. I bought some DBA high temp DOT 4 to put in the Beringer front brakes. I might have to investigate the dry boiling point . It was a lot cheaper than the 660. @@TheBikeStig

[@SteveMuir]

310c dry and 216 c wet. $13. Thanks to Google.

[@austinpowell7417]

Mate are you still able to get this for $18 a bottle?

[@robertandrews6555]

Hmmmm, been using Dot 5.1 in my V8 cobra clutch...... Has always needed changing every spring as the pedal gets progressively more and more spongey, and the gearbox more and more notchy with the heat in traffic..... Am thinking about trying RBF 700 this spring after watching this vid..... Cheers from England 👍🏻

[@TheBikeStig]

cheers mate, sounds like you might be driving that thing the way it was meant to be driven ... awesome. I'd be keen to hear if it fixed the problem for you mate.

[@RoyRacing185]

Good to know I should change my RBF700 fluid with 5.1 when I ride my trackbike at -40 celsius (haha). But thanks, interesting to see them against each other.

[@TheBikeStig]

haha, yep, apparently we need steel spikes on the tyres at those temps too 🙂

[@Superjabbs]

Ive been down this road many times. I use to be a big Castrol SRF user. Then I tried all the Motul RBF range. Then I came across Endless RF-650. I wont use anything now.

[@TheBikeStig]

I'll be taking a look, thanks mate

[@Angel-rg9dh]

Castrol SRF "should" be better, at least in theory due to its very high WET boiling point... what did you notice to stay on the RBF? Thanks

[@Superjabbs]

​@@Angel-rg9dh much better peddle feel

[@TheBikeStig]

@@Angel-rg9dh for me they would all feel the same as I don't have the fluid in the bike long enough for the moisture to build up. For serious racing, I am still happy to run the Motul, truth is they are all good.
