hi all. just a thought. i have heared that the td125 is restricted by the exhaust, hence there is an acropovic exhaust system available for it. however upon looking up pictures of the tw 200 and more so the tw 225, they apear to have exact same exhause system, in terms of conection. douse anyone know if it is possible to use a 225 eghaust on the 125 and would this give any improvement in performance. cheers
