Still nothing on the weight reduction? I am going to guess that it has to do with the wheels... if you think about the heaviest parts of the bike firsts is the engine then the frame and on to the wheels. oh and of course the battery. The rest of the little parts should be significant.
I don't think that the battery can account for all that weight loos, and I haven't read anything about the wheels being made of a different material. It is a bit of a mystery how they got that weight to just disappear. Is the frame of the Gunner the same as the frame that the Judge is on?
