NEW YORK — Harley-Davidson is considering closing its main motorcycle assembly facility in Pennsylvania and moving production elsewhere as it aims to lower costs and cope with a sales downturn, a company spokesman said Wednesday.

Spokesman Bob Klein said the Milwaukee-based company is exploring ways to reduce costs at its York location. That could include a move, though he declined to say where. The York facility employs about 2,400 workers and consists of two motorcycle factories that assemble its Touring and Softail motorcycles.

Klein said the York facility is not competitive as it stands.

He said the company is working with its union, the Association of Machinists and Aerospace Workers, as it conducts a review on the facility. He declined to say what other locations might be under consideration for a move.

Pennsylvania Sens. Arlen Specter and Bob Casey sent a letter Tuesday to Harley Chief Executive Keith Wandell, saying the facility is important to the local economy and calling on the company to protect the factory's jobs.

The review of the facility is part of a broad cost-cutting plan that Harley, the top maker of heavyweight motorcycles, launched in January as it battles shrinking profits and a downturn in sales of its iconic bikes. The company has announced plant consolidations and is aiming to cut between 1,400 and 1,500 jobs over the next two years. Part of that plan is to cut between 525 and 575 hourly workers at York.
