What action should you take if your motorcycle's throttle sticks?

When faced with a situation where your motorcycle's throttle sticks, pulling in the clutch and rolling off the throttle is the safest and most effective action to take. By pulling in the clutch lever, you disengage the engine from the rear wheel, allowing you to maintain control of the motorcycle without accelerating uncontrollably. Rolling off the throttle helps to reduce engine power and return the motorcycle to a manageable state.

This method preserves your ability to steer and brake effectively, which is crucial for safety. It's important to remain calm and not attempt rapid acceleration or drastic maneuvers, which could lead to loss of control. The other options are less effective: accelerating could worsen the situation, turning off the engine might cut power abruptly and cause the wheels to lock up, and keeping your foot on the brake could lead to losing control in the event of an unexpected surge in speed.
