## DOT4 MOTUL RBF 660 Racing Brake Fluid FL 500ml This high-performance DOT4 MOTUL RBF 660 Racing Brake Fluid is the ideal choice for demanding motorcycle and scooter riders who expect the highest braking system performance. Specifically designed to withstand the extreme temperatures generated by racing brakes, both carbon and ceramic, while minimizing air access to brake cooling. This fluid is also suitable for conventional steel disc brakes and hydraulic clutch systems. ### Exceptional Performance in Extreme Conditions MOTUL RBF 660 stands out with its exceptional resistance and thermal stability. Its very high dry boiling point (325°C / 617°F) exceeds the requirements of DOT 5.1 (260°C / 500°F) and DOT 4 (230°C / 446°F) standards, ensuring effective braking even in the most demanding conditions. This fluid contributes to better aerodynamics by reducing the need for brake cooling air intakes. ### Effective in All Weather Conditions The high wet boiling point (205°C / 401°F) exceeds the requirements of DOT 5.1 (180°C / 356°F) and DOT 4 (155°C / 311°F) standards, guaranteeing effective braking even on wet surfaces. DOT 3, DOT 4, and DOT 5.1 brake fluids absorb moisture from the air, which lowers their boiling point and increases the risk of "vapor lock." MOTUL RBF 660 minimizes this risk, ensuring safety and braking confidence. ### Quality and Reliability of the Motul Brand The Motul brand is synonymous with quality and innovation in the field of lubricants and operating fluids. By choosing MOTUL RBF 660 brake fluid, you are investing in the safety and reliability of your motorcycle or scooter. Remember to change the fluid regularly according to the manufacturer's recommendations. The package contains 500 ml of fluid. ### Specifications: * DOT Classification: DOT4 (polyglycol based with borate esters) * Volume: 500 ml * Compatibility: Can be mixed with DOT3 and DOT5.1
