The bottom picture is a shot of the shift rod support brace. It basically takes most of the play out of the shift assembly as the shift rod has a good bit of movement where it enters the transmission. With the support installed on the stock rearsets it made a very noticeable difference while shifting. With the support and the Sato rearsets installed it shifts like nothing I've ever rode before! I would say for the price ($70.00) its definately a good mod.
