Transmission Oil; Oil Recommendation - Honda CRF250R Owner's Manual

Transmission Oil

Refer to Important Safety Precautions on page 23.
Using the proper oil, and regularly checking,
adding, and changing oil will help extend the
service life of the transmission and clutch. Even
the best oil wears out. Changing oil helps get rid of
dirt and deposits. Operating the engine with old or
dirty oil can damage your engine.
Running the engine with insufficient oil can cause
serious damage to the clutch and transmission.
