This product says it fits but it has six holes and I have five studs

Vortex is great. I replaced the entire set with 525 pitch sprockets and chain and do not regret it. This combination is Yamaha’s recommendation and I now know why. It’s way smoother but feels tighter than the flimsy 520 kit. The weight added is marginal for the power this Fj09 bike delivers!

Looks great compared to stock. Hold up great to wheelies and all sorts of abuse. Bought a -3 tooth over stock and made my FZ into a wheelie machine
