Yamaha GRIZZLY 125 YFM125GT Owner's Manual page 202

If your ATV has stalled or stopped and you
believe you can continue up the hill, restart care-
fully to make sure you do not lift the front wheels
which could cause you to lose control. If you are
unable to continue up the hill, dismount the ATV
on the uphill side. Physically turn the ATV
around and then descend the hill.
If you start to roll backwards, DO NOT use the
rear brake to stop. The ATV could easily tip over
backwards. Instead, dismount the ATV immedi-
ately on the uphill side.
