Check this out. MOTUL uses NITROGEN [not air] when they fill these bottles so you can be assured that the fluid inside is pure and not already degraded - it is fresh. The RBF600 far exceeds the standards for DOT 4 and the extremely high dry boiling point of 594 deg F and wet boiling point of 421 deg F provides fade free operation.
This is the good stuff people.
The BIGGEST reason to buy THIS STUFF HERE is it's resistance to sucking up water. Our brake systems are open meaning they are vented. So condensation is a real thing. RBF600 is extremely hydrophobic which is a VERY good thing.
