  • various characteristics such as wear resistance, detergency, heat resistance, oxidation stability, less oil consumption, and low frictional loss, are required for the lubricating oil for engines.
  • parts such as a shift drum, a shift fork, and a shifter gear in a gear box operates under user's manual operation of a clutch lever and a shift pedal during running, and the gear changes.
  • the friction characteristics of the parts vary depending on a lubricating oil used, and this may change the sense felt by the user (shift feeling).
  • PTL 1 discloses a lubricating oil composition containing an imide compound, a metal-based detergent, and zinc dithiophosphate as a lubricating oil composition that is excellent in a performance required for an engine system and an increase in coefficient of friction for a wet clutch.

  • a user disengages the clutch with the clutch lever, and then operates the shift pedal to rotate the shift drum in the gear box, and with the rotation of the shift drum, the shifter gear is shifted with the shift fork to mesh with the dog teeth. The user finally releases the clutch lever to fasten the clutch, and thus the upshift is completed.
  • the user feels a sense of roughness due to sliding of the parts in the gear box, which is a poor shift feeling, or the user does not feel such a sense and obtains a sense of smooth sliding, which is a good shift feeling.
  • the present invention has been made in view of the aforementioned problems, and an object of the present invention is to provide a lubricating oil composition for two-wheeled motor vehicles that satisfies the performance required for a lubricating oil for engines and achieves a good shift feeling while a high coefficient of friction is kept in a wet clutch.
