Our friends the Brother Speed from the USA are like us still building and riding Choppers. They like to ride fast and far, so most of their chops have big inch modern motors. That is also the reason why they are chopping Dyna's! They have been doing that for quite a while now. We just chopped our first Dyna this winter, more later. We hope we can show you the end result of the Brother Speed Dyna chopping project too!
