MADISON, Wis. (AP) -- Milwaukee-based Harley-Davidson would become the official Wisconsin motorcycle under a bill proposed in the Legislature.

Milwaukee Democratic Rep. Leon Young says the idea came from a family member of Sgt. Jeremy Vrooman, who was killed last year while serving in Iraq.

Young argues in a letter to his colleagues that the long and storied history of Harley-Davidson in Wisconsin makes it appropriate to honor it with the distinction of being the official state motorcycle.

William S. Harley and Arthur Davidson built the first Harley-Davidson motorcycle in 1903 in Milwaukee. The company was incorporated four years later and remains based in Milwaukee.

Wisconsin doesn't have an official motorcycle, but it does have an official song, insect, dog, dance, and tartan.
