Additional Notes

  • The PGO Big-Max brake fluid specification applies to a hydraulic brake system, meaning the braking mechanism relies on pressurized fluid rather than a mechanical cable to actuate the brake components.
  • Both the 110/PS-110 and 50/PS-50 variants share the same fill guidance, with the correct fluid level sitting between the minimum and maximum marks on the reservoir.
  • The fill range defined by the min and max marks represents a service-level check rather than a fixed measured volume, so no discrete capacity figure in milliliters or ounces is specified for either variant.
  • The normal use condition applies to both the 50cc and 110cc configurations, indicating the stated fill range is referenced under standard operating conditions.
