(Reuters) - Harley-Davidson Inc <HOG.N> said on a conference call on Tuesday it would lay off "casual workers," or temporary hourly wage workers, first as a part of the company's newly announced reorganization plan.

Harley-Davidson said it plans to reorganize and reduce its workforce to streamline functions and become a more agile manufacturer. The reductions will cost the company $20 million to $25 million.

Due to the reorganization Harley-Davidson said would also lose both contingent workers, or contractors, and some full-time employees. The company did not indicate how many jobs would be impacted.
