MDK Speed - Motors

MDK Speed motors deliver strong, reliable horsepower and torque. Our motors make the kind of power that is perfect for less skilled riders, as well as being very effective in the hands of a top pro rider. These features are what you need to be up front on every start, and to turn fast, consistent lap times.

Of course, all of the horsepower in the world doesn’t mean a thing if your motor doesn’t get you to the finish line. Every motor we build uses components that have been torture tested on the track, and NDT’d in the shop (Non Destructive Testing), and in some cases we’ll even perform destructive testing. Our experience in metallurgy, aerospace manufacturing, and forensic analysis gives us the opportunity to not only get you big horsepower, but help your bike last longer. All this ensures that the products we sell you are of the highest quality and deliver outstanding performance..
