SYM X-Pro

Brake fluid capacity & service interval

SYM X-Pro uses brake fluid with a capacity range of 0.15 to 0.25 liters. Service intervals occur every 30000 km or 24 months. The data covers 5 configurations.

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

Additional Notes

  • All five SYM X-Pro configurations listed specify a hydraulic brake system, meaning brake fluid is contained within a closed hydraulic circuit rather than a mechanical cable arrangement.
  • The X-Pro 100 (2010-2015) and X-Pro 125 (2010-2016) share the same fill specification: fluid level maintained between the reservoir minimum and maximum marks, with no change interval defined in the specifications.
  • The X-Pro 125i (2017- ) carries the same between-min-and-max reservoir specification as the earlier 100cc and 125cc variants, maintaining consistency across the displacement range on that point.
  • The X-Pro 50 E4 (2017-2020) follows the same level-based specification as the other configurations, with fluid kept between the marked reservoir limits under normal use conditions.
  • The X-pro 50 E5, XE05W4-EU (2020- ) is the only configuration in the specifications to include a defined change interval, set at 30,000 km or 24 months, whichever comes first under normal use conditions.
  • A 24-month brake fluid change interval, as specified for the X-pro 50 E5, reflects the hygroscopic nature of brake fluid, which absorbs moisture over time and lowers its boiling point regardless of distance traveled.
  • The dual-condition interval of 30,000 km or 24 months on the X-pro 50 E5 means the time-based threshold can trigger a fluid change before the distance threshold is reached, particularly relevant for low-mileage use.
