Choose your quantity
Select Single 1 Bottle for 500 mL, or Case of 20 Bottles for 10 L. With the single-bottle option selected, quantity 2 provides 1 L and quantity 3 provides 1.5 L. These are package volumes, not a guarantee that a particular quantity will flush your car. Confirm the service quantity before ordering.
Compatibility and handling
Check the vehicle and brake-system manufacturer’s fluid specification, including any ABS and cold-temperature requirements. Do not mix with petroleum-based or silicone-based brake fluid. The bottle label instructs users to keep the cap tightly closed and use promptly after opening. A high boiling point does not replace correct brake maintenance or cooling.
RF650 questions
Is this a universal-fit fluid?
It is not matched by vehicle shape or mounting points, but chemical compatibility still matters. Confirm the required fluid specification before use; “universal” does not mean suitable for every brake system.
Why do some RF650 pages list a different boiling point?
Our newer bottle photo and Endless Japan show 320°C dry. Endless Japan explains that its displayed rating changed to account for manufacturing variation without a change to the ingredients.
How much do I need for a track day?
Use your vehicle’s service procedure or your race shop’s advice to establish the flush volume and event spares. Start with our RF650 track-day preparation guide for a practical ordering checklist.
