Do you need a motorcycle license in Illinois if your motorcycle is under 150cc?

Yes, you are required to have a Class L license which will allow you to operate any motor-driven cycle under 150cc. The only exception to this is if you are operating a moped (pedal-driven cycle), that is 49cc or less and ha less than 2 braking HP. In IL, you can take a free MSF course ($20 refundable deposit needed) that upon completion will allow you to add the M classification to your license which will allow you to operate ANY motor-driven cycle.
