If twisting the throttle several times doesn't free it, what should you do next?

Using the engine cut-off switch and pulling in the clutch is the appropriate response when twisting the throttle several times does not free it. This action helps to quickly disengage the engine from the wheels, which is crucial for maintaining control of the motorcycle. By cutting off the engine's power, you minimize the risk of the motorcycle accelerating uncontrollably. Pulling in the clutch also disengages the engine from the transmission, allowing the rider to safely slow down or come to a stop without losing control.

In situations where a stuck throttle could lead to dangerous acceleration, this action provides the rider with the ability to manage the motorcycle without the throttle's involvement. It creates a safer environment while the rider assesses and addresses the throttle issue.
