Honda just couldn't help themselves because they thought they were so smart and smug and had to make it a 3 speed box, probably the next thing they will bring out is a 5 speed with overdrive just for the sake of it to make people think how clever they are. Stick to single speed and make it strong and reliable. My mate has told me the latest gearbox I put in his is fine, that is because he hasn't used it and isn't game enough to, and I think it will be a while before he bothers with it again
