Harley-Davidson is further consolidating its business categories, as the Milwaukee brand announced last week that it would be discontinuing its sidecar line. Interest in Harley-Davidson sidecars has been waning over the years, and with the introduction of the Tri-Glide family of trikes, Harley-Davidson has seen its sidecars sales plummet. The 2011 model year will be the last year the Harley-Davidson sidecars will be available, and the company plans on shutting down production once the forecasted 2011 number of sidecars is finished at the factory.
