To safely handle a slippery surface, it's essential to slow down before reaching it. Reducing your speed allows for more control over the motorcycle, decreasing the risk of losing traction on a slippery surface. When approaching areas that could potentially be slick, such as wet roads or gravel, reducing your speed gives you ample time to react to any changes in traction, enabling you to maneuver more smoothly and safely.
Maintaining a constant speed or attempting to accelerate quickly can lead to a loss of control, particularly on surfaces that don't provide adequate grip. Sudden braking is also detrimental as it can cause the wheels to lock up, leading to skidding and possibly losing total control of the motorcycle. Therefore, gradually slowing down is the most effective way to navigate slippery conditions safely, as it allows for better handling and a lower risk of accidents.
