A collection of classic motorcycles including some owned by the Du Pont family was auctioned by Bonhams in Las Vegas, with sales reaching $1.8 million, nearly double the pre-auction estimates.

The auction included 50 motorcycles and 113 lots of spare parts from the Du Pont family including some from the personal collection of E. Paul du Pont, founder of Du Pont Motors and one-time president of Indian Motorcycles. The Du Pont collection accounted for $1 million. The auction also featured 70 other rare motorcycles.
