Yes they are works, do require set up and PC makes very little money on the ones they sell, the only reason they sell them is so they can use them on the team bikes. They are incredibly well made, and if you are really, really fast, then get them. If you ar really rich and want them -get them. If you are one of us who are neither, get your suspension revalved by a competent shop for your riding style and you will be very, very happy. I had PC do my KTM and they made it awesome. MXtech, race tech, factory connection, enduro engineering, provalve,dicks racing and the rest are worth the money. Know that ANY good shop will continue to work with you to get it right if you are not happy with it when you first get it back.
