Oil ?

Can castrol full syn. edge be used in this bike(klx 450r)?

Do not put automotive oil in your motorcycle. The additives in the oil are harmful to your clutch. Most automotive oil is also not designed for high-rpm use.

For a cheap reliable oil change, grab a gallon of Honda GN-4 10w40 or Yamalube 10w40. If you want to go full syn I recommend Maxima Extra.

Hope that helps


The heavy duty diesel oils can be a good choice. Rotella T6 synthetic 5/40 is even MA rated and its cheap.


Torco 10-40 full synthetic here. I run car oil in my car and motorcycle oil in my KLX. I would rather spend 15.00 dollars a quart for piece of mind rather than 1500.00 to rebuild the motor.:ride:
