The auction will feature 105 collectible and one-of-a-kind items in honor of the Harley-Davidson's 105th anniversary, and will run through September 4 in conjunction with MDA's Jerry Lewis Labor Day Telethon online auction.

"Harley-Davidson has always gone above and beyond to help my kids," said MDA National Chairman and Telethon star Jerry Lewis. "This auction is a way to get some fantastic Harley-Davidson items that won't be available anywhere else in the world -- all while helping MDA's mission. It's a win-win."

The auction will help support MDA's programs of research, services, public information and summer camp, which provides kids with a week of accessible activities such as swimming, horseback riding, fishing and arts and crafts.

Special items up for bid include a Harley-Davidson 105th Anniversary Heritage Softail® Classic motorcycle and a 2009 Rocker™ motorcycle fully accessorized with Genuine Motor Accessories installed by Harley-Davidson technicians live on Main Street at the Lakefront during the company's 105th anniversary celebration.

Other featured items include a behind-the-scenes tour for four of the recently opened Harley-Davidson Museum, with a two-night stay at the Courtyard by Marriott in downtown Milwaukee; a Fender guitar autographed by the Jonas Brothers, Tim McGraw, and the members of the group Blondie; and a custom-made Harley-Davidson themed Fender Stratocaster guitar. The guitar is one of three Harley-Davidson branded, production-quality prototype guitars: one will be placed in the Fender Museum, one will be placed in the Harley-Davidson Museum and the third will be auctioned to benefit MDA.

Also featured are a custom-made Harley-Davidson owner's ring from Jostens, with diamonds and onyx and personalized with the winner's name; an American flag that was flown over Harley-Davidson's corporate headquarters; and artwork by Harley-Davidson artists David Uhl and Scott Jacobs.

Since 1980, Harley-Davidson's family of dealers, customers, employees, suppliers and Harley Owners Group (HOG) chapters have raised more than $65 million for MDA. Every year, Harley-Davidson riders selflessly volunteer their time to visit nearly a hundred MDA summer camps across the country. Riders host barbecues, give sidecar rides, provide temporary tattoos and let thrilled youngsters sit on their motorcycles.
