Is that in the handbook for the motorcycle endorsement, or just the regular Class C?
When I went for my M1 in CA, all that was required was the written skills test for a permit, then another written skills test and a ride test on a 250cc or larger bike, administered by a DMV employee.
If you wanted to bypass the ride test at the DMV, you could take the MSF and pass, then just take the written exams.
I highly recommend the MSF.
