I'm in the market for a rear shock upgrade and have been planning on going the race tech rebuild route. But, I thought I'd look for some used aftermarket options first. A guy on my local riders forum has a Penske 8970 triple w/remote reservoir from his 07 zx6r and is asking $600. What would need to be done to fit this on my 09? I am going to call penske or a local suspension shop tomorrow because I would at least like to get it refreshed and sprung for me as well. But if the modification and refresh are gonna cost me another $300 I may have to pass. can you guys recommended any other year aftermarket options that will fit the 09-12 to open my options a bit? Thanks!
