All these theories about if you weight the rear and the front wheel and you sum the weights....i dont know. To be sure, a very good way is that: You go to a dump to find 2 motorcycles, one heavy and one light. You weight them with this way that its easy, then you cut in pieces and you weight the pieces to find out how accurate is this. By doing this with 2 motorcycles you will find the deviation of this method, so you will make a kind of ''formula'' to help your fellows motorcyclists. Anybody that have time to do this please let ASS know!!
