Additional Notes

  • For the Cota 4RT (2005-2013), the coolant level specification is expressed as a range rather than a fixed volume, with the fill target sitting between the minimum and maximum marks on the reservoir or sight glass.
  • The 2005-2013 configuration carries a 12-month coolant change interval under normal use conditions, meaning calendar time rather than mileage or hours drives the service schedule.
  • Starting with the 2014 model year, both the Race Replica (2D/4E) and the 260 (ED/3E) variants introduce an additional check interval of once per race or every two hours of operation, which was absent from the earlier 2005-2013 specification.
  • The Montesa Honda Cota 4RT Race Replica 2D/4E and the Cota 4RT-260 ED/3E share identical coolant service specifications for 2014 onward, including the same level target, check frequency, and annual change interval.
  • The per-race or two-hour check interval on the 2014 variants reflects a competition-oriented maintenance cadence, tying coolant inspection directly to event-based usage rather than elapsed calendar time alone.
  • Across all three configurations spanning 2005-2014, the annual 12-month coolant change interval remains consistent, indicating a shared baseline service requirement regardless of variant or model year within the covered range.
