I rolled a 2002 Foreman 2x in 1 night on the ice with friends.We were running back and forth on the lake and when we would get to the end,we would turn around and BS,have a cig and some beverage and run back again. Well I did a power slide and hit an awger hole which flipped me on my side...the machine on my ankle and a head bounced off the ice (with helmet). Fkipped it back up and went on with life. The next time it happened,I was going much faster and same thing happened...only this time,it slammed me hard enough to taste blood in my mouth and they said when it went airbourne,it came down ontop of me. They helped me up and uprighted the machine which was upside down. I was hurting bad and called it a night. Ran the machine back to the house where my wife and daughter had to help me get some clothing off so I could see if any ribs were sticking out. Had broken ribs and a valuable lesson taught to me that night. And a few weeks of major pain. Never did it again . On another accasion,was on a ride and had a front tire dig in an a steep hill with a curv,was thrown from the machine and turned to see it rolling down the hill at me. No time to move so I placed my hands under my chest,best that I could,so I wouldn't get broken hands etc..the dang thing rolled over me from feet to head. The lower back got it real good that time....thought it was broken and was scared to move...but my hands were safe! LOL...helmet was on as well,or my head would have had 600lbs rolling over it. Finally rolled over slowly and wiggled me toes and had movement. After a while,I was slowly able to get up and go to the quad and still don't know how I got on it,but it was sitting there,running and waiting. Caught up with my friends as they were coming back to see where I was. I told them what happened and they said we would go very easy back home. I since sold it,but plan on a SxS in the near future. I'm in my mid to upper 40's and not a wild man on machines as they cost too much to abuse.....but it happens fast. Not a toy. If I had no helmet on either time,I might not be here to tell about it. Wear your helmets.
