Hi guys new here. Just picked a new 2013 FZ8 yesterday. I pretty sure that the 13 and 12's are the same bike besides the forks and shocks. I want to get two brothers slip on exhaust but there site has two different part numbers for the years. But other site will say 11-13 will work. I want to be sure it will work because I know the stock exhaust can has a different look from the 11 and12. Also goes the same for tail tidy fender eliminator kit and yamaha's lower cowling. Question is that even though I have a 2013, parts that say 2011 and 2012 will work?
