Maintenance Fundamentals
Brake Fluid
Do not add or replace brake fluid, except in an
emergency. Use only fresh brake fluid from a
sealed container. If you do add fluid, have the
brake system serviced by your dealer as soon as
possible.
NOTICE
Brake fluid can damage plastic and painted surfaces.
Wipe up spills immediately and wash thoroughly.
Recommended brake fluid:
Honda DOT 4 Brake Fluid or equivalent
54
Recommended Coolant
Pro Honda HP is a pre-mixed solution of
antifreeze and distilled water.
Concentration:
50% antifreeze and 50% distilled water
A concentration of antifreeze below 40% will
not provide proper corrosion and cold
temperature protection.
A concentration of up to 60% will provide
better protection in colder climates.
NOTICE
Using coolant not specified for aluminium engines or
ordinary tap water can cause corrosion.
Crankcase Breather
Service more frequently when riding in rain, at
full throttle, or after the scooter is washed or
overturned. Service if the deposit level can be
seen in the transparent section of the drain
tube.
