The swingarm seems to work pritty good for just duning riden and what not. I deffentely would not go jumping anything huge with it. The power coating is starting to chip a little where the bolts come in contact with the arm.
As for the motor, It rips when everything elce is up to par. Only realy had it running good at the dunes once.
It was running down outher cubs that claimed to have pulled 100 HP on a dyno with no problem. That was also my first time riden in the sand. If you look in the video section Their should be some video of it in their. Make it easy and do a search in the video section for moneybags
