ABSTRACT:
A modified SAE No. 2 friction machine is used to evaluate the clutch friction properties of motorcycle lubricants in a process comprising measuring the torque after a break-in period at three temperature points within the ranges 30.degree.-60.degree. C., 70.degree.-90.degree. C. and 110.degree.-150.degree. C. over a 10 second period while the speed of the motor driving the clutch plates varies from 0-300 rpm and the clutch plate pressure is held at 50 psi.
