I’ve got about 500 miles on the Roxor and there is one thing I’m not sure about. The motor runs a very quiet tone off road but when I hit the highway, the tone changes. It goes from a nice mechanical purr to a rumble monster. I have no idea why. Is it the turbo boost coming on? Is this clatter normal under certain loads? Seems to start in 3rd gear and above and at times, will get back to a normal purr (or not.) Normal??
