Just wondering what exactly a "Case Saver" does.

To me it looks like it fills the gap between the front of the chain and the crankcase to keep the chain from bunching up there if it were to break.
Guess I kinda answered my own question, but is this all they do?

 

the case is expensive and a aftermarket case saver is only 20 dollars. mine also protects my shifter. ive never broke a chain but i hear about it. people must really use chains up i replace mine whenever my adjustment is all used up.

 

If your bike throws a chain, it is most likely that it will end up going right through (and thus ruinning) a $250 side case. A $25 case saver will prevent a thrown chain from damaging the case. Pretty simple, but works! Well worth $25.

Back when I had my Warrior, it threw a chain. That wasn't fun. It did have a case saver on it, but it didn't help too much. It ripped the case saver right off and put a crack in the case (fairly small, but it still leaked out of it the hole). In my opinion, if you throw a chain, the case saver isn't going to help too much.

 

7 of 10 times a good quality case saver (thick and covers both the stator cover and the shift shaft) will save your case...$25 for $250+ of prevention....seems like good math to me...

 

Another good reason for a case saver, besides the obvious, I've seen quads and bikes throw chains without the protection of a case saver. It not only protects your side case, but it can prevent the chain from being thrown to the side after hitting the case and possibly ripping your boot (if worn) or shoe/foot right off. I've seen what a thrown chain can do to a boot and foot, it's not a pretty sight.

 

My case saver has saved me a lot of money numerous times!
