The kit is a complete bike, except for the one little machine screw that they shorted me. It even comes with a battery, once it's together all you need to add is fuel and oil. The seat is handmade, I don't know if it's made in-house or if they outsourced it. Most of the bike is made in-house. The seat is a very nice piece, it has the correct design that looks like an oak tree, upon further inspection you realize it's an eagle with it's wings spread, just like the original H-D seat. The seat is quite comfortable, when you put some weight on it bows down like a saddle, the positioning will take some getting used too, the whole bike feels really tall. There are only a couple small features that deviate from the original bike, but without a picture or intimate knowledge of the original H-D you will never know it.
