Motul RBF 660 Racing Brake Fluid (500ml) | Ultra-High Temp DOT 4 Fluid | By Motul


When you’re pushing your e-moto to the edge — whether it’s a Sur Ron, E-Ride Pro SS 3.0, Talaria, or RFN Rally Pro — every drop of braking performance matters. Motul RBF 660 Factory Line is engineered for the toughest race environments, with one of the highest boiling points available in DOT 4 fluid to resist fade, vapor lock, and inconsistency under extreme load.


Perfect for hydraulic disc brakes on high-performance e-motos, this 100% synthetic fluid is nitrogen-sealed to preserve shelf life and purity — ensuring you’re getting race-day performance every ride.

⚠️ Important Compatibility Note:

 

  • Do not mix DOT 4 with DOT 5.1 brake fluid — despite their similar labels, they have different chemical properties. Mixing them can cause the fluid to gel, resulting in brake failure and loss of control.

  • Never mix mineral oil with DOT fluids (DOT 3, 4, or 5.1). These are incompatible systems — combining them can cause seal degradation, internal corrosion, and total brake system failure.

Always check your manufacturer’s brake fluid specification before servicing your system.
