Night and day difference with the new chassis. But the pre '09 models can be improved with a Tru-Track or other brand stabilizer which limits the side to side motion of the power unit when cornering in long sweepers. Easy to install. The motor, primary and trans float on rubber mounts but as a unit are connected to the swingarm and that creates the problem.
And depending on the miles of the unit you rode, replacing the motor mounts (usually the front one) and the swingarm rubber isolaters with better ones, will also help handling. All of these items are easy to install but alignment should be checked when changing any of these, also easy to do.
