I was looking online at the 2003 600 zrs well i thought they were zrs then they said 600 zl. Then i looked at the 2002 and they all said ZR 600 in 02. Why did they change them to a zl. Also what zr/zl, Should I get. I saw theres a XC Zr 600, then theres a zr 600 ss, zr 600 efi, zr 600 ESR, then theres the zl 600, zl 600 efi, zl 600 ss, zl 600 ESR. I am looking for some thing that is over all good.
