Default Understanding Chain Spacers?

     

I wanted to start a new thread, because i really dont understand why i might need a spacer. It seems like using the spacers is something racers do aftermarket, because nobody markets chain spacers. What's the deal?

I've never heard of spacers either, not for your chain anyway, but I've seen a number of posts talking about a spacer with respect to 0@X type chains. People are saying you need to run "a Spacer" for these chains. I dont get it, what a sprocket spacer for alignment or something? Is this just some bs that is being tossed around or what? Like the dude who posted he was looking to buy a super powerband.

The spacer is only required on the CRF 450 and possibly the CRF 250 when running an O or X ring chain. It's only about 1mm thick and goes behind the front sprocket, but without it the chain will rub on the cases and eventually rub a hole in them- not a good thing! Fastway sells them I know, and Ironman sprockets come with a "spacer" built into the countershaft (aka front) sprocket.

Cool but if you spaced the countershaft sprocket out wouldn't it make the chain not run true to the rear sprocket causing accellerated wear?

It is only 1mm, that is a very small amount. I had to put one on my CRF when I went to a Renthal O Ring chain. Better that rubbing on case.
