Motul 101667 RBF 660 Dot-4 100 Percent Synthetic Racing Brake Fluid - 500 ml

This is some of the best brake fluid you can get. High heat resistance that translates to a more positive pedal feel for longer.

I use this for my 2017 Civic Hatchback to pair it with my Goodridge SS brake lines and the Wunderladen Racing brass rear caliper bushings. This has also contributed to my brake pedal to be firm. Other thing that I felt was less fading from the brakes. You’ll never go wrong with Motul.

I use Motul exclusively in my track motorcycles. Zero issues and great performance in a demanding environment.

All good

I bought this for my track bike. My GSXR 600 felt a little odd braking into turn one at Summit Point Main. You have to brake hard after the long straight and this fluid makes a difference you can really feel. The brakes feel the same lap after lap. The lever feels much more consistent each session all day long. The next day I used it at Shenandoah which has some 22 turns I did not bleed the brakes and they felt great. My super moto was a night a day difference as well. I also used in my CBR 954 for the street and the brakes felt close to new. I have used other high end DOT 4 fluids and this brake fluid is the best I remember. The rest of my street and dirt bikes are being converted to this fluid as well. Highly recommend.

Amazing performance. Increased my braking distance overlaps by nearly 37% over the 600 version. New pads as well to make it as fair as possible. My lap times were amazing, lowering 1.5 to 2.3 seconds average.I wanted to also point out some information about the production date stamped in the back. As I see some reviews and it might mislead new users if they don’t know about the new format. Motul used to have the ” . “with format day.month.year before and now they use in many countries the “ / “ with the format of year/month/day as production date and 2 years from production date is the best performance of the fluid. 3-4 might be ok for street driving but is best to be under the 2 year production mark so you can get the best value for your money.As you can see in the pictures attached the production date is not 2030 and I am not from the future lol 😂.It is year 2020/ month January/ day 30.Just wanted to point this out. I hope is helpful.

No problems after a year of use in harsh conditions. Hard to tell any difference in actual pedal feel but has not faded or failed.

By far the best brake fluid for motorcycles, the bike breaks much better, for real!
