Executing a turn while ascending a hill is somewhat different . In this situation , the rider shifting weight to the outside of the turn will be moving his weight to the uphili side . This maneuver requires more exertion than is required on flat ground . In addition , due to the fore - and aft weight distribution of the ATV , it is usually desirable for the rider to shift his weight forward . This is most controllably per formed by rising into a standing or crouching position so that body weight rests completely on the footpegs . It is reasonably easy to lift the front wheel from the ground by accelerating , and this tendency is exacerbated while ascending a hill .

Any discussion of the turning characteristics of the machine must address a caution relating to stability recovery . If the ATV should tilt too far during a turn and the operator momentarily lose controlled balance , the close proximity of the rear tire to the point where the operator may place a fout on the ground makes this action hazardous . The large tires and short wheel base result in a high probability that the rear tire will contact the operator ' s foot . Additional shielding beyond that already provided by the fender is not feasible as it would reduce ground clearance .

RESARIAL

The stability of an ATV may be enhanced by adding a fourth wheel , as has been done by one of the nianufacturers . Forces tending to over turn a 4 - wheeler laterally must overcome a greater righting moment due to the greater dimension from c . g . to the axis of contact with the ground , as diagrammned above . ( Note that the actual points of tire contact with the ground are idealized in the figure . ) The effective increase in stability of a 4 - wheeler should be beneficial particularly in unstúsle turns such as downhill or rough terrain turns .
