I run a tyson roundhouse swinger on one of my drag bikes. Has been one stout unit so far and the tig welds look top notch. I also run a swingarm shop swingarm on a trail bike with no issues. I do agree I wouldn't run a tyson swingarm on trails or mx unless it's reinforced more. That swingarm shop add looks like they posted a banshee swingarm pic. They have been in the game for awhile.
