The American Motorcyclist Association and Black Book have developed a Motorcycle Value app for Android and iPhone. For $1.99, it offers a quick way for the general public to get an idea of what their vehicle is worth. The app is updated monthly and includes the current retail value, the original MSRP and the trade-in value of powersports vehicles manufactured since 1981. It is available in the iTunes store and the Android Marketplace under the search term "AMA Values."
