Even for the casual rider, changing your brake fluid and giving the system a good bleed to remove any trapped air is recommended every year or so. If you're on the track or racing, choosing a quality brake fluid with a high boiling point will keep your brakes from overheating. We recommend bleeding your brakes on a track machine once every 3-5 track days to retain precious brake feel and performance. Choose from top sellers like Motul 5.1, the track ready Motul RBF600 and the top selling Castrol. If your brakes are feeling sluggish, it could be time to bleed them and run new fluid through the system.
