This is a very nice used bike. I bought it from a dealer with the pipes and tuner already installed so I have no idea what they do for perfomance other than I think that you have to have the tuner if you want the pipes. I did add the chrome fuel gauge/fill cap the chrome strip on the battery box the chrome digital oil gauge and the fork bag. There are two sets of keys with fobs for the security system and manual. This bike drives like a dream. I just had it out two weeks ago and I love riding it I just don't ride it enough as you can see by the mileage. I am including a his and hers helmets if the buyer wants them. I set the reserve at $10000. If you have any questions please feel free to contact me through ebay. I would be happy to send more pictures if you want them. I reserve the right to end the auction at any time as I have it for sale locally too. Thanks for looking.
