Outrageously High 617° F Dry Boiling Point!
Super, Super High 400°F Wet Boiling Point!
100% Synthetic Racing Fluid - DOT 4 for extreme temperature & racing applications. All types of hydraulic brake and clutch actuators requiring non-silicone synthetic fluid.
Widely exceeds the DOT 3, DOT4 and DOT 5.1 standards (except for DOT 5.1 viscosity at - 40°C).
Extreme thermal resistance and stability :
Very high boiling point (325°C / 617°F), superior to conventional DOT 5.1 non silicone base, DOT 5
silicone base fluids, and DOT4. Motul RBF 660
enables effective braking even under extreme conditions.
Efficient when rainy :
Very high wet boiling point (204°C / 400°F) far exceeds the requirements of DOT 3 & 4 & DOT 5.1 enabling brake efficiency while rainy.
Reduces the risk of the “vapour lock” phenomena. Amber in colour.
Do not mix with silicone (DOT 5 silicone base) or mineral base fluids (LHM).
