Harley Davidson introduces the V-Rod Muscle

Harley-Davidson Inc. has hired supermodel Marisa Miller to promote the V-Rod Muscle, a motorcycle aimed at a younger, hipper demographic than Harley’s traditional customer base.

The V-Rod Muscle is a sporty, sleek bike introduced this year. It has a long, low profile inspired by drag racing and an engine that was co-developed with Porsche, the German sports car maker.
