Here is what I have. It is from an XR500
May not be what your looking for, the mount is really heavy duty. You could cut a lot of it away.
It's really small overall size , 11 inches total length and about 3 inches around at the end. So if you don't have much room it would be good.
Sounded good on the XR but I had an aluminum one I put on it.
There is one small dent, it has some surface rust but is solid, I can blast it if you want.
