Ace Mechanic
XP-4 75th Anniversary
The major purpose for creating this site is to preserve and promote the history and legacy of the Ace Motor Corporation and the Ace four cylinder motorcycle.

Additionally, I hope to be able to pull information out of the little nooks and crannies where people have been hiding Ace information and get it out into the open for everyone's use and benefit.

The only thing I want to get out of this venture, other than that stated above, is to try to find out new information about, and pictures of, my grandfather, Joe Stephan, who worked at the factory in the service department as a mechanic from 1921 to 1924.
