On the road, you learn to slow down for safety. On big, heavy bikes, around bigger, heavier cars, that’s just the best approach. Off-road, on a light bike? You’re actually far more stable when you apply some speed. The gyroscopic force of the wheels will keep you upright, momentum will carry you over or through tough terrain like deep sand. Moving your weight backward has the combined effect of adding traction to the rear wheel, where the power is being applied and taking weight off the front, allowing it to deflect and ride over the stuff that it’s hitting.
