Clutch Lubrication
Many motorcycles have a wet clutch, where the clutch plates are immersed in oil. Some oils make the friction plates in the clutch slippery so that the clutch does not engage properly when shifting gears, or the clutch slips when the engine exceeds a certain torque level. Some oils contain friction reducing chemicals. A properly specified motorcycle oil will still allow for the appropriate lubrication and cooling of a motorcycle clutch, whilst maintaining 100% of the drive to be transmitted by the clutch, even under arduous operating conditions. One element of the JASO-MA standard is a friction test designed to determine suitability for wet clutch usage. An oil that meets JASO-MA is considered appropriate for wet clutch operations. Oils marketed as motorcycle-specific will carry the JASO-MA label.

Famous quotes containing the word clutch:
“Go out of the house to see the moon, and ‘t is mere tinsel; it will not please as when its light shines upon your necessary journey. The beauty that shimmers in the yellow afternoons of October, who could ever clutch it? Go forth to find it, and it is gone: ‘t is only a mirage as you look from the windows of diligence.”
—Ralph Waldo Emerson (1803–1882)
