Motul RBF 600 Factory Line Racing Bromsvätska DOT 4 – 500ml

Extreme braking performance under the most demanding conditions

• Very high dry boiling point of 312°C - maximum braking confidence on the track and road
• Excellent wet boiling point of 205°C - maintains performance even when absorbing moisture
• 100% synthetic DOT 4 racing Brake Fluid - developed for extreme heat
• Suitable for all hydraulic braking and clutch systems (non-silicone)
• Meets and exceeds the DOT 3, DOT 4 and DOT 5.1 standards

The Motul RBF 600 Factory Line is the ultimate choice for riders who demand absolute braking performance. Developed in the world of motorsport, it is equally suitable for sporty road bikes, Supersport motorcycles and trackday machines. This 100% synthetic DOT 4 Brake Fluid is designed to withstand the extreme temperatures that occur during intensive use of steel or carbon braking systems.

With an exceptionally high dry boiling point of 312°C, the RBF 600 offers unrivalled resistance to “vapor lock” - the dangerous phenomenon in which Brake Fluid forms gas bubbles when overheated. Even when the fluid absorbs moisture over time, its wet boiling point remains at 205°C, well above the required standards, ensuring that your brakes continue to perform reliably under all conditions.

Application and compatibility

Suitable for all hydraulically operated braking and clutch systems that require a non-silicone synthetic fluid. Ideal for:

• Racing motorcycles with steel or carbon brake discs
• Supersport motorcycles and performance road bikes
• Hydraulic clutch systems subject to high thermal loads

The RBF 600 can also be used in conventional braking systems, but it delivers its full potential in competitive or heavily loaded situations where heat management is crucial.

Use and maintenance

Always replace the fluid according to the manufacturer's recommendation, taking your usage into account. Avoid mixing it with lower-quality Brake Fluids or fluids of another type, such as silicone- or mineral-based fluids. Store the fluid in a tightly sealed container to prevent moisture absorption.

Q&A - Frequently asked questions

Can I also use the RBF 600 on road bikes?

Yes, absolutely. Although this fluid was developed for racing, it is also suitable for road use. Its high boiling points provide maximum safety during sporty riding or in mountainous terrain.

What is the difference between RBF 600 and standard DOT 4?

The RBF 600 has a much higher dry and wet boiling point than standard DOT 4 fluids. This means it is more resistant to overheating, allowing the brake pressure to remain constant for longer - even during intensive use.

Is Motul RBF 600 compatible with my braking system?

Yes, as long as your system specifies a DOT 3, DOT 4 or DOT 5.1 fluid. Do not use it in systems that require DOT 5 (silicone-based) or LHM mineral fluids.

How do I know when it is time to replace the fluid?

Brake Fluid absorbs moisture from the air, causing its boiling point to decrease. Regular replacement (annually or after heavy use) guarantees the best performance and prevents vapor lock.
