Allen Millyard's Viper V10 motorcycle isn't the first on the street, in fact there may have been many before it. For instance, Paul, one of our readers, sent these photos taken at Daytona a few years ago. It looks like a Boss Hoss with an engine swap. While I applaud the effort the builder put into this, I think the Allen Millyard build wins on appearances and most likely handling. It's amazing how different the two bikes look while using the same huge powerplant.
