I have purchased another quad so we have two now. I sold all my other vehicles this winter and we have just had the Rancher for the last 9 months so we've been riding double. Anyway, we have some fairly treacherous terrain here so I figured I would take my wife out to do a little technical climbing practice. She got hung up on one climb and I had to grab the controls to save us.
So, I take her down to the fire road below and decide I'm gonna teach her how to "self arrest" as I call it. You know: Release throttle, throw yourself all the way forward, lock down all 3 brake controls, prepare to possibly slide backwards, and generally get stabilized. Then slowly ramp throttle back up until impending motion and release brakes to begin forward movement again.
We're on a somewhat flat road ~10 feet wide; one side straight up 10 foot cut out face, other side down the mountain at about 50 degrees. I've got her leaned way forward with all the brakes locked as if we were on a hill. I tell her to slowly ramp the throttle up and release the brakes when you feel it get ready to move. Then this all happens in 1-2 seconds: She does exactly that but had forgotten it was in reverse from turning around. Since she's leaned so far forward, when it moves backwards she looses her balance and falls forward and then her thigh hits the throttle and jacks it WFO! We go flying backwards at redline and just as I'm getting to the bars they somehow flick all the way to one side before I can grab them and we do an abrupt 90 degree turn towards the drop off down the mountain. I'm shreaking BRAKES and she's just generally shreaking and she's still face down on the front rack. Just as the rear tires hit the edge I grab the bars. At the same time she grabs both the levers hard and captures my hands. She's finally squeezing the **** out of the levers but my fingers are in them so the brakes don't work and my hands are caught. So there we go, sailing off the embankment, in reverse, on the rev limiter...

Luckily the brush, briars and tree limbs slowed us down. About 20 feet down we hit a 3 inch tree with the rear rack that stopped us. It took a winch job to get my poor quad out, but it was undamaged.
