Wow, people are worried about a stem mount fitting or not. . . As I said - its about 1/4" higher than the original stem mount but you gain the ability to essentially mount any ram ball mount you want. Here are two pictures of the MotoReva stem adapter, one of the ball and the other with a plate mount with some accessories on it.
