BatteryThis motorcycle is equipped with a
sealed-type battery. Therefore it is not
necessary to check the electrolyte or fill
the battery with distilled water.l
If the battery seems to have dis-
charged, consult a Yamaha deal-
er.
l
If the motorcycle is equipped with
optional electrical accessories, the
battery tends to discharge more
quickly, so be sure to recharge it
periodically.
