I hAVE AN '02 f4i and it's awesome....Im 6'1 200lbs and fits just right....The price tag on it could be lower b/c of the miles on it...and make sure if its still under warranty or if its not to check the Cam Chain Tensioner. It goes bad on these f4i's other than that its cool...if you want more power i'll sell you my Busa that sits in my storage b/c this 600 does the job
