What Case Saver Prevented your Heartache

15 posts in this topic

I did some searching on here to look for a case saver to put on my '07 YZ450F found a couple things, but not what I wanted.

What case savers have any of you used that have saved your case in a real situation? IE your chain broke and should have smashed a big hole in you case, but did not because of an after market case saver.

If not, what brands do you recommend?

Thank you!

My 426's flimsy stock case saver saved me...just gave the case some "love marks" but no holes.

It bent it pretty bad when the chain broke, so I got a T.M. Design case saver and fits perfect, made of delrin to slide easier and looks like it would protect a lot better than the stock one!

My chain master link came off and wrapped around my stock case saver and it held up but it was bent up though and surprisingly the 2 bolt tabs that go into the case didn't break which would of split my case. I think it would of split my case open if the chain didn't also grab my shifter too. The chain then went to my shifter and used that for a can opener and had lunch.....Hundreds of dollars worth on that one. I don't like the design of the OEM one on my bike because of the skinny hook like ends which look like it gives the chain something to grab onto. Some people don't use them because of the possibility that the chain could grab it and pull it off which will split the case.

Interesting! I defiantly need a new case saver. Just need to know which one will protect the best. I don't want to invest the $ and not have it do what its supposed to do...

I had a TM on my '03 YZ450 when the chain went. I didn't see any damage to the case. I found a couple of extra links, fixed the chain with two master links and kept riding the rest of the day.

The actual purpose of the gizmo commonly called a case saver is as a guide to keep the chain from lifting so far off the front sprocket that it derails, and to keep it centered if it lifts off slightly. It was not intended to fend off a broken chain, and while there are heavy duty versions made that probably could, the weak point in the concept is the mounting points on the case, as tnl mentioned. Having one is still more protection than not, but it's far more effective to apply preventive maintenance to the chain itself by buying a good one in the first place, keeping it lubed, the tension set right, and not running it in such a worn state that it becomes a risk to break.

Can you post a pic of yours? Do you have a problem with mud getting in it if the conditions are muddy?

Here is what i run on my 08. Made by HAMMER HEAD, nice and beefy. After loosing the link retainer and damaging the case on the "07", i wont trust the standard case saver as it is junk.

They call it a chain guard and it actually fits over the skinny little peice of metal they call a case saver. Never had a problem with mud in it. It gets caked, but it doesn't effect the chain's performance.

I have seen chains bunch up under the "case saver" and break the case at the mounting holes.

It would be nice to have a 3rd mount
