Additional Notes

  • The Montesa Honda Cota 4RT hydraulic brake system specifies a fluid level maintained between the minimum and maximum reservoir marks, which is a standard service fill reference rather than a measured volume capacity.
  • For the Cota 4RT covering 2005-2013, the brake fluid service interval is a change every 6 months under normal use conditions.
  • The 2014 Cota 4RT Race Replica variants 2D and 4E introduce an additional inspection interval not present in the 2005-2013 specification, requiring a fluid check every 2 hours of riding or after every 1 race.
  • The Cota 4RT-260 variants ED and 3E from 2014 share the same brake fluid service structure as the Race Replica, with both a check at 2 hours or 1 race and a full change at 6 months.
  • The 6-month change interval applies across all three configurations in the specifications, meaning calendar time rather than mileage or engine hours governs the full fluid replacement schedule.
  • The addition of a race-based check interval in the 2014 variants reflects the competitive use context of those models, where brake fluid condition is assessed per event rather than solely on a time basis.
