Hello - I've got some GSXR rear rotors that have been machined to make them lighter. For an older GSXR (2000-2003 version), you lose 1.19 pounds. On the 2004-present versions, you lose 0.805 pounds. These should fit 2001-2009 GSXR600, 2000-2009 GSXR750, and 2001-2009 GSXR1000. Price is $65 shipped to the lower 48 states. I can ship outside the lower 48 but it will be more $$ (send me your address and I'll get a shipping quote). Paypal works fine for me. I'm trying to sell them on Ebay as well if you want to do a search there and read a little more. Any questions, let me know. Thanks!
