I just received mailing in today's mail announcing going out of business auction for Chicago Cycle, Inc. in Lincolnwood, IL. Auction is this Saturday, Oct. 30th beginning at 10:00 am. Preview is Friday. Chicago Cycle is (was) a very large dealership, with a primary focus toward the sportbike community, but then again, aren't they all. I am surprised by this move, as Chgo cycle has always been a prominent sponsor of the annual International Cycle Show in Chgo.
This link should get you there.

Mike Peterson runs a pretty good auction, however, I am not sure if internet bidding is offered this time. I expect there will be a large volume of helmets, jackets, rain gear and other apparel. You may be able to get a good deal on something you need. I got a good deal on some J&M headsets at the Chgo. Sports & Cycle (different company) auction last year.
