I can’t seem to find the spec on the dot4 break fluid. Is synthetic or non synthetic recommended?

Tough crowd. I doubt it makes any difference using synthetic or non-synthetic. In my cupboard is a bottle of Heavy Duty DOT4 that I used on my last bike.

More importantly, do not store an unsealed bottle of DOT4. It is hydroscopic and will rapidly accumulate water. Throw away any leftovers you may have.

you broke your breaks.

Seriously though I had a question under a similar subject, DOT3 was phased out and DOT4 was being phased out, DOT 5 is available and supposedly compatible with the previous two. Has anyone tried Dot5 in the clutch or brakes?

Dot 3/4 combination is now available.

Hi


Motul Dot 4 is what I'm running in the K1600.


BTW if you want the very best which isn't needed on a K Bike or any machine that isn't racing it's Motul Dot 4 660

To obfuscate the topic a bit more, DOT 5.1 is compatible with DOT 3/4. But not with 5.0 which is Silicone based. Those specifiers have a sense of humor.......

I've too have been using Motul Dot 4 RBF600 for years. It's more hygroscopic than 'regular' Dot 4 and must changed annually.

I'm using ATE TYP200 DOT4, only because it's what I used in my BMW automobile, and I had half a can of it left over from that last flush and instead of letting it sit and go to waste, I flushed out the K1600 brakes with it. Feels A-OK.
