This is the OEM windscreen from my 2005 Suzuki GSXR1000 - it will fit 2006 models as well, possibly others but I'm only certain about 05-06 GSXR1000.

Part is nearly new, in excellent condition with no cracks, scratches, etc.  The bike was converted to racetrack use a few hours after it was purchased and all the street parts came off and were packed away in their near-mint condition in case I ever wanted to put the bike back to street use.  I've since sold the bike so I'm selling all the OEM parts I have for it, check my other auctions - if you're looking for nearly-new parts for this bike odds are I'm selling them.  :)
