BATTERY
This component requires constant care and diligent servicing. Make sure that the liquid is completely covering the plates;
if not, top up to the right level using distilled water (never use natural water even if it is drinkable). If the vehicle is not used
for a certain period of time (1 month or longer), it is necessary to recharge the battery from time to time. The battery tends
to run down completely in about three months. When placing the battery on the motorcycle, mind not to invert the con-
nections: connect the black earth cable to the negative terminal and the red cable to the terminal .
