Swingarm pivot play?


New Member
I was installing my rear wheel and adjusting the chain when I noticed that when I checked the chain slack by pulling the chain down at midpoint that I would get a very slight clunk. The rear wheel was off the ground as I had the swing arm supported by a pit stand. I could feel a very tiny amount of movement at the swingarm pivot for and aft. Also, if I put a small prybar between the swingarm and frame I could move the swingarm left to right approximately 1mm. It looks like the inner bearing race is moving within the bearing. Is this normal? Am I missing side spacers?

You could look at an online parts diagram (e.g., partsfish.com) to see if you are missing anything. There are adjustable spacers in the footpeg brackets that might be misadjusted, though I am not sure that would result in the side play you found.

In any case, the fore/aft play would worry me enough that I'd disassemble and inspect the unit.
