We took our famous skull and made it 35% bleater and 20% more distressing to get the scariest mirrors on the market. The mirror head is 3" x 4" with 3" round glass. The slightly arched stem places the center of the mirror 4 3/8" above and 5 1/2" to the side at the mounting point at the handlebar. The mounting mechanism is something never seen before; the joint ball is held by two pins that allow easy and fast adjustment. Includes screws for multiple H-D applications.
