Oil Information


Motorcycle Oil

We recommend using Japanese Automotive Standards Organization approved motorcycle oil. JASO-MA and JASO-MA2 approved oils are designed for single unit engines where the wet clutch, gearbox, and engine used the same oil. Do not use automotive oil, it has too many friction modifiers and can cause clutch slippage, and gear box pitting. Reference your service manual, it will provide change schedules, viscosity, and the correct amount of oil to use. (On the back of the oil container there will be a JASO box with individual certification number)

Automatic Transmission Fluid can be used with bikes that use separate oils for the engine, clutch and gearbox. Alto clutches will operate properly with any of the ATF fluids on the market. (Ford “Type F” fluid will give a more positive clutch engagement, and is more suitable for competition riding.)

Worn or damaged clutch components will also affect clutch performance, thoroughly inspect the clutch assembly.

Alto motorcycle clutches can be used in a “Wet or Dry” application. For wet applications soak clutches for 10 to 15 minutes before installation. For moist application soak clutches for 10 to 15 minutes, wipe them off with lint free cloth before installation. For dry applications install right out of the box.
