Motul RBF 600 is a high-performance DOT 4 racing brake fluid widely considered the industry standard for kart racing brake systems that use DOT 4 fluid. Designed for motorsports environments, RBF 600 delivers reliable braking performance, excellent fade resistance, and consistent pedal feel under demanding racing conditions.
With a dry boiling point of 312°C (594°F) and a wet boiling point of approximately 204°C (399°F), Motul RBF 600 significantly exceeds the requirements of standard DOT 4 brake fluid and provides stable performance during repeated high-temperature braking cycles.
RBF 600 has become one of the most widely used brake fluids in karting due to its combination of high temperature capability, consistent brake feel, and reliability across a wide range of racing conditions.
Ideal for:
• All kart racing brake systems that use DOT 4 brake fluid
• Shifter kart brake systems
• Sprint kart braking systems
• Solid non-ventilated kart brake rotors
• Motorcycle and high-performance hydraulic brake systemsMotul RBF 600 is formulated for racing environments where braking systems experience repeated heavy braking zones and sustained heat buildup. The high boiling points help prevent vapor lock and brake fade while maintaining consistent braking performance throughout a race session.
