SYM Mask E4/E5

Brake fluid capacity & service interval

SYM Mask E4/E5 uses brake fluid with a capacity between min and max. Service intervals occur every 30000 km or 24 months. The data covers 3 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

TypeSpecifications
Mask 50 E5 (2021- )
  • Use: Normal
  • Between min and max.
  • Change 30000 km/ 24 months
Mask 125 (2019- )
  • Use: Normal
  • Between min and max.
Mask 50 E4 (2019-2021)
  • Use: Normal
  • Between min and max.

Additional Notes

  • The SYM Mask E4/E5 brake fluid specifications cover the hydraulic brake system across all listed configurations, with the fluid level maintained between the minimum and maximum marks on the reservoir.
  • The Mask 50 E5, with a starting year of 2021, is the only configuration in the specifications that carries an explicit change interval, set at 30,000 km or 24 months under normal use conditions.
  • The Mask 125 and Mask 50 E4 share the same specification format, referencing only the min-to-max fill range without an associated change interval in the provided data.
  • A min-to-max fill specification in a hydraulic brake system context indicates a level check and top-up procedure rather than a measured volumetric capacity, meaning no fixed fluid quantity is assigned to the service operation.
  • The 24-month interval on the Mask 50 E5 reflects a time-based replacement criterion, which in brake fluid servicing accounts for moisture absorption over time regardless of distance traveled.
