Maintenance Fundamentals
#
Cleaning and Lubricating
After inspecting the slack, clean the chain and
sprockets while rotating the rear wheel. Use a
dry cloth with chain cleaner designed
specifically for O-ring chains, or neutral
detergent. Use a soft brush if the chain is dirty.
After cleaning, wipe dry and lubricate with the
recommended lubricant.
Recommended lubricant:
Drive chain lubricant designed
specifically for O-ring chains
If not available, use SAE 80 or 90 gear oil.

Do not use a steam cleaner, a high pressure
cleaner, a wire brush, volatile solvent such as
petrol and benzene, abrasive cleaner, chain
cleaner or lubricant NOT designed specifically
for O-ring chains as these can damage the
rubber O-ring seals.
Avoid getting lubricant on the brakes or tyres.
Avoid applying excess chain lubricant to prevent
spray onto your clothes and the motorcycle.
Recommended Coolant
Use only genuine HONDA PRE-MIX COOLANT
without diluting with water. Genuine HONDA
PRE-MIX COOLANT is excellent at preventing
corrosion and overheating.
The coolant should be inspected and replaced
properly by following the maintenance
schedule. P. 36

NOTICE
Using coolant not specified for aluminium
engines or tap/mineral water can cause corrosion.
