A "motor-driven cycle" is a motorcycle with a 149cc or less engine size. Note: you may not operate a motor-driven cycle on the freeway. It is not advised to take anything less than a 250cc motorcycle on the freeway, even that could be dangerous. Besides a California Motorcycle License, Current Registration & License Plate, and of course Insurance; at minimum, your street-legal motorcycle must have:Tires with sufficient tread for safe operation.Headlight, taillight, brake light, and turn signals.Front and rear brakes.A horn and two mirrors.Hopefully you find this answer to be helpfull.
