Illinois considers new license requirements for big motorcycles
Instead of offering licenses in just two size classes — one for cycles with an engine displacement of less than 150 cubic centimeters, like off-road bikes and scooters, and another for all other sizes — Illinois would add a third category for the bigger motorcycles, possibly starting at about 600 cc. And drivers would have to test on the size bike they intend to ride.
