When Harley Davidson stopped production of the Buell 1125 back in 2010, the founders of Ronin Motor Works created the Ronin Concept Motorcycle, a spectacular superbike that will continue on after the demise of the Buell 1125. Ronin 47 is built around the revolutionary engine and frame of the Buell, but has had a major facelift with many mechanical and cosmetic changes to give it a furiously aggressive streetfighter look.
