For the reference, I contacted Techspec and asked them myself. They said the left side and tank pads are identical on both models. However, the right (exhaust) side is slightly different so that it follows the contour of the battery access panel. Kawasaki redesigned this panel in 2010. Both pads would technically "fit", but the 2010+ pad would overlap the gap on the battery access panel on the 2009. Therefore, you would have to remove the pad to access the battery.
