The Yamaha YZ450F is not street legal in the United States. It is designed and manufactured as a closed-course competition motorcycle and does not meet the requirements for street use. It lacks necessary safety features such as headlights, taillights, turn signals, and a horn, and its emissions are not regulated for road use.
While it is possible to modify a YZ450F to make it street legal, this process can be complex and costly, and it may not be legal in all jurisdictions. It is important to check the local laws and regulations before attempting to modify a motorcycle for street use.
