It is illegal for anyone over the age of 88 to ride a motorcycle.

The Law Explained

You cannot hop on a Harley within city limits if you have celebrated your 89th birthday. This highly specific age restriction was likely enacted by a fretful city council concerned about the reflexes of the elderly in rapidly growing traffic. The arbitrary choice of 88 remains a mystery, perhaps tied to a specific local incident involving an octogenarian joyrider.
