Coolant Recommendation
Coolant
Servicing Your Honda
Using coolant with silicate inhibitors may
cause premature wear of water pump
seals or blockage of radiator passages.
Using tap water may cause engine
damage.
Your motorcycle’s liquid cooling system
dissipates engine heat through the coolant
jacket that surrounds the cylinder and
cylinder head.
Use Pro Honda HP coolant or an
equivalent high quality ethylene glycol
antifreeze containing corrosion protection
inhibitors specifically recommended for
use in aluminum engines. Check the
antifreeze container label.
Maintaining the coolant will allow the
cooling system to work properly and
prevent freezing, overheating, and
corrosion.
Use only distilled water as a part of the
coolant solution. Water that is high in
mineral content or salt may be harmful to
the aluminum engine.
The factory provides a 50/50 solution of
antifreeze and water in this motorcycle.
This coolant solution is recommended for
most operating temperatures and provides
good corrosion protection.
