What must a rider do to avoid rolling backward when starting on an incline?

To avoid rolling backward when starting on an incline, a rider should hold the rear or front brake. This action is essential because it prevents the motorcycle from rolling down the slope while the rider prepares to engage the throttle and start moving forward. By applying the brakes, the rider can maintain control and stability, allowing them to smoothly transition from a stationary position to moving uphill without the risk of losing traction or control.

Releasing the throttle entirely can lead to a loss of power and control, which is not advisable when starting on an incline. Revving the engine high may seem to provide more power, but it does not directly address the need for stability when transitioning from a stop. Leaning forward might help in weight distribution, but it does not provide the necessary brake control to prevent rolling backward. Therefore, utilizing the brakes effectively is the key to ensuring a safe start on an incline.
