Checking oil level
Check oil level regularly each
time you stop to refuel.
Only check the engine oil when
the engine is at normal operat-
ing temperature as the oil level
can vary by up to 0.39 in
(10 mm) in a hot engine or a
cold engine at extreme outside
temperatures (14 °F / -10 °C).
Wait at least five minutes after
switching off the hot engine for
the oil to collect in the sump.
Checking the oil level after the
engine has only been used for a
short time or is only just warm
could lead to wrong interpretati-
ons and thereby to an incorrect
oil fill because the cold, more
viscous oil takes longer to flow
back into the sump. This can
take up to 12 hours at extreme
temperatures (14 °F / -10 °C).
To avoid damage to the engine:
– Never exceed the maximum
oil level.
Always keep the oil level above
the minimum mark.
Always check the oil level with
the motorcycle standing up-
right.
• Check the oil when the engine
is at normal operating tem-
perature
• Read the oil level at least five
minutes after switching off the
engine
• Make sure that the motorcy-
cle is upright
– ensure that the surface is
level and firm.
