Guidance

Harley-Davidson continues to expect to ship 228,000 to 235,000 Harley-Davidson motorcycles to dealers and distributors worldwide in 2011, including 45,500 to 52,500 motorcycles in the fourth quarter.

to previous guidance of 34.0 percent to 35.0 percent. The Company continues to expect capital expenditures of between $210 million and $230 million, which includes $70 million to $85 million to support restructuring activities.

Restructuring Update

Harley-Davidson has lowered cost estimates related to the restructuring of its production operations and now expects all previously announced company-wide restructuring activities to result in one-time charges of $480 million to $495 million, including 2011 charges of $70 million to $80 million.
