Additional Notes

  • The Kymco Top-Boy 100 hydraulic brake system does not specify a fixed fluid volume. Instead, the level is maintained between the reservoir's minimum and maximum marks, which is the standard fill method for closed hydraulic brake circuits.
  • For the Top-Boy 100 (2007-2010) under normal use conditions, brake fluid is checked at every 2000 km interval and replaced on a 24-month cycle regardless of mileage accumulated.
  • The Top-Boy 100 (2007-2010) also carries an initial service check interval of 1000 km, which applies separately from the recurring 2000 km normal-use check schedule.
  • The Top-Boy 50 (1999-2006) hydraulic brake system shares the same min-to-max fill specification but is serviced on a 1000 km check interval under normal use, half the distance of the later 100 cc variant's recurring interval.
  • No fluid change interval appears in the Top-Boy 50 (1999-2006) normal-use specifications, whereas the Top-Boy 100 (2007-2010) carries an explicit 24-month replacement requirement, representing a notable difference between the two variants.
