Extreme specific pressure synthetic lubricant for gearboxes with oil-bath clutch separate from 2-stroke motorcycles. This fluid was developed to meet the requirements of the JASO MA2 and API GL-4 standards required in integrated wet clutch gearboxes with shear stability characteristics and optimized low and high temperature viscometric behavior favoring a pass easy '' speeds. An additive that provides excellent anti-wear and extreme pressure properties enhanced by a friction modifier to reduce friction and noise operation, sticking and slipping clutches.
