I destroyed a side case before I fitted a case saver.
I got a little carried away with mine, it's 4mm stainless and mounts on the two rear engine mounts as well as the sprocket cover screws.
I did file the sprocket cover so it sits flush over the case saver.
There is clearence to run a 17 tooth front sprocket
In 10,00 years when all traces of VMX are long forgotten some one will find my case saver, I wonder what they will think
