During a turn, what is not recommended?

During a turn, decelerating is not recommended because maintaining a consistent speed helps with stability and control. When you decelerate, especially abruptly, it can shift the motorcycle's weight and potentially lead to a loss of traction, increasing the risk of a skid or loss of control during the turn.

On the other hand, accelerating slightly through the turn can help stabilize the motorcycle and improve cornering dynamics. Maintaining speed is often a safe approach, as it contributes to the balance and stability of the bike. Shifting gears is also acceptable, depending on the situation and the riding conditions, as it can help the rider maintain power and control. Therefore, maintaining a stable speed or a slight acceleration is preferred to ensure safety and effective handling during a turn.
