Chain replacement

if all else fails, talk to a technician at a trusted shop about your selection or go with the stock. you can never go wrong from the recommend factory settings.

Ok. You lost me. "The working load sets a lower limit on pitch..." I don't get it. Seems like the size of the smaller sprocket would set the minimum pitch, not the load.

It's a chain on a sprocket. I don't see how the load on either end would determine the distance between links. Rather it seems that the spacing and size of the teeth and diameter of the sprockets would determine that.

If it were only the load, heck every chain would have itty-bitty links. Problem is, they wouldn't mesh with the sprockets.

What am I missing, here?

More questions to follow, concerning this post. But perhaps an answer to my first couple will lead me to my own answers.

Thanks!

Bike uses a 520 chain AND sprockets. Sprockets must match the chain.

I am no expert....

But when you put the pulling force on the chain with the front sprocket I would think the the chain will deflect some of the force by "bending" slightly...maybe?

think of a flat bed semi trailer or bridge they have a curve to them and when force is applied to them they flatten out.

Nah. The semi trailer and bridge in your example are bent against the load, simply to accept a heavy load that is laid upon them. They are static objects with a curve built in, to make them stronger against a load laid vertically. (In the case of the bridge, it's actually gravity vs. the weight of the bridge more than it is the traffic on it.)

With a chain-driven motorcycle, all the motive force begins on the chain at the front sprocket.

With a motorcycle chain, under normal, forward operation, there is actually only a "load" on the top side of the chain, as it enters the forward sprocket.

This action creates a load on the top and backside of the rear sprocket, as the rear tire has friction with the ground.

It gets way more complicated, the deeper you want to go, but that's it in a nutshell.

Cheers!
