Motul RBF 660 Race Brems-und Kupplungsflüssigkeit (universal)

Motul RBF 660. All types of hydraulic actuated-brake and clutch systems requiring a non-silicone synthetic fluid.
Specially designed to resist to high temperature of racing actuated-brake (steel or carbon) and clutch systems.

Extreme thermal resistance and stability :

The very high boiling point (325^0C), superior to conventional DOT 5.1 non silicone base / DOT 5 silicone
base fluids (260^0C / 500^0F mini) and DOT 4 (230^0C / 446^0F mini) enables an effective brake even under extreme
conditions.

Efficient when rainy :

The very high wet boiling point (205^0C ) superior to conventional DOT 5.1 non-silicone base fluid (180^0C /
356^0F mini) and DOT 4 (155^0C / 311^0F mini) enables to keep an efficient brake system when rainy. Indeed, DOT
3, DOT 4 and DOT 5.1 brake fluids have the property to absorb humidity in the air, which reduces their boiling
points and increases the risk to get the phenomena called " vapour lock ".
The wet boiling point is measured by humidifying the product with about 3.5 % of water.

All types of hydraulic actuated-brake and clutch systems requiring a non-silicone synthetic fluid.
Specially designed to resist to high temperature of racing actuated-brake (steel or carbon) and clutch systems.
