I should probably stay out of this, but I ain't. Most of the jap companies got their start building copies of Triumph BSA and Nortan twins, Now they all build v-twins. What I am getting at, is copying which is what they do best.The only two "real things" are Harleys with their v-twin and Triumph with their twin. Most everything else is just a copy. I not going get into it with anyone on which is best. I own both, and will not voice my prefaces.
