Greetings!
Take a look at
http://www.eti-fuelcel.com or call them at 805-449-1735.
They have two models for your bike. One is an OEM replica, and the other is a "gut buster" which allows a little more room for hanging off.
They claim a weight savings of 9.17 lbs.
I haven't yet tried any of their products personally, but they appear to be the real thing.
Hope this helps.
