You know mickal1025, it had occured to me a while back that your engine mount could possibly be adapted to the rear swingarm of a fully suspended bike.
There are some bikes out there that have a rear shock up out of the way and still have a decent V-frame so a mount like yours fastened/welded to the rear swingarm would keep the chain tensioned properly and allow for a decent rear suspension also.
Most likely still have lower vibration than a solidly fixed engine.
