Recommended Engine Oil
Type:

Be careful not to allow any dirt or foreign
materials to enter the engine.

API SG, SH, SJ, SL or SM with
JASO MA, MA1 or MA2
Viscosity: SAE 10W-40
Capacity: 0.8 L (0.8 US qt)

the engine oil level by the dipstick on the cap.

NOTE

A. Oil Filler Cap/Dipstick

NOTICE

The oil level should be between upper and
lower level lines on the dipstick.

○Do not add any chemical additive to the oil.
Oils fulfilling the above requirements are fully
formulated and provide adequate lubrication
for both the engine and the clutch.

Although 10W-40 engine oil is the recommended oil for most conditions, the oil viscosity
may need to be changed to accommodate
atmospheric conditions in your riding area.
