With all of the upgrades to the 09 GSXR, it is definately a formidable bike, not that it wasn't before, but the new lighter weight and engine mods are friggin SWEET!!! I concur with previous post about the arm, but to each his/her own really. It looks awesome. I am going to stretch the "Angel" (My Busa) and look into getting the 2010 1K. Angel is probably going to turn into a trailer bike just for shows.
