Harley-Davidson's Battle of the Kings, an annual contest started in 2015, is the largest dealer custom build competition in the world. So how exactly does it work? In a nutshell, dealers must build a custom Harley-Davidson using a budget no bigger than half the cost of the original model, and 50 percent of the aftermarket parts used have to be H-D Genuine Motor Accessories. Teams can have their build compete in any of three categories—Dirt, Chop, and Race—using any model from the range (not including trikes and CVO machines). And this year, for the very first time, US trade school students were invited to partner with local US dealers to help spin wrenches in the trenches, as it were. Under the watchful eye of seasoned Harley mechanics, these students were introduced to the wildly creative customization process and helped build some of the coolest customs in the world along the way. Heather Malenshek, Harley-Davidson chief marketing officer, said, "Battle of the Kings allows these students to apply their creativity and funnel this passion into real-life applications that will ride with them for generations."
