Harley-Davidson (NYSE:HOG) is set to report earnings on Tuesday, and as usual there are a few areas that investors will want to keep their eyes on to make sure this company is firing on all cylinders.

The numbers that will likely move the company's stock are Wall Street's estimates. The street will be expecting earnings per share between $1.08 and $1.09, revenue around $1.5 billion, and 76,500-81,500 motorcycles shipped in the first quarter. Lastly, guidance will need to be maintained at 279,000-284,000 shipments for the full year.

Although these Wall Street estimates are important for Harley Davidson investors, there are five areas long-term investors should really focus on before they get swept up in Wall Street's quarterly numbers game.
