Looking for opinion on my sprocket

5 months ago by alf to c/motorcycles

I think my sprocket is getting a bit worn and need to be changed, but I’m looking for a second opinion. It doesn’t have the «shark fins» I’ve been reading about, but the sprocket fins look a bit thin and worn.

Would appreciate someone’s opinion it.

They're definitely worn, you can see the valleys are getting elongated and the peaks are getting thinner. I always found it helpful to find a picture of a brand new sprocket to compare with.

If you can, it’s best to replace both front and rear sprockets and chain together.

Also, give your wheel a good inspection. It looks like cracks have formed near the visible bolts:

I don't think that's a crack, seems like a comstar style wheel, so that's probably just where the two pieces meet.

Good eye! I wouldn’t have noticed. That seems problematic. Does that imply I should get new wheels?

I can’t say from the pictures but definitely give them a thorough inspection. Clean them until spotless then take a good look.

That trucker is definitely toast. Time for replacement.

Overdue, I would say.

That's done for. Time to change both gears nd the chain.

Way over due. Change both sprockets and chain.

Is the chain anywhere near needing replacing (any stiff links)? Usually you wouldn't change the sprocket until the chain needs to be replaced.

I think I have read in the past that you should always do them both because as the chain stretches the sprocket tends to wear to match the stretch, but I have reused sprockets without any problems.

Anyways it looks fine to me.
