Sturgis, S.D. – They’ve banged handlebars for more than a century, and nowhere is the battle between Harley-Davidson and Indian Motorcycle more apparent than at the Sturgis Motorcycle Rally.

The rally — which continues through Sunday and is expected to pull in about 500,000 people — is the epicenter of spirited competition between Harley and Indian, the last remaining major U.S. motorcycle companies. Milwaukee Journal Sentinel
