The original Yamaha swingarm pivot bolt, part number 1E2-22141-00-00, was discontinued a few years ago, so we hunted down an alternate bolt and nut set that fit properly on these bikes. The kicker is that it's a little longer than the stock bolt so you will need to trim about 10mm off the length.

Also, the head is different than the stock hex-headed bolt, so you'll have to use a 10mm hex key wrench to stop the bolt from spinning when tightening it and may need to remove the stock nub from the frame that stopped the stock part from spinning when being tightening (depends on how worn your frame is).
