Royal Enfield is a brand best known for its light- to middleweight bikes that is only just recently getting back into the world of two cylinders. As we await the arrival of the new twins in dealers, RE brought a stunning new concept to the EICMA motorcycle show that’s a different kind of machine. It’s called the Concept KX and it’s a muscular 838cc V-twin-powered bobber inspired by the 1140cc V-twin Royal Enfield KX of the 1930s.
