The Grizzly 700 is equipped with a selectable 2WD/4WD system with a lockable front differential. In general the use of 2WD is perfect under standard trail riding or sporty conditions. But when the going gets tough just switch to 4WD, especially when the trail becomes harder or climbing on steep, narrow sections. If you are going through mud or even more miserable terrain then you can engage the differential lock 4WD.
