How Do Motorcycles Work?

I developed a feature on the old site called "How Do Motorcycles Work?" I did most of it five years ago but kept expanding it. It's a complex of about 60 files so I have been putting off converting it for the new Motorcycle Views site -- until now.

I spent the better part of two days redesigning the feature to present the material differently. The result is a new feature, "How Do Motorcycle Parts Work?" This is an expandable feature with plenty of room for growth.
