What happens if you roll the throttle away from you?

• A. The motorcycle slows down.
• B. The throttle locks.
• C. The engine stalls.
• D. The motorcycle speeds up.

Answer: (A)

Closing the throttle by rolling the grip away from you reduces the engine’s power output. With less fuel and air being drawn in, the engine RPM drops, and in gear that drop translates into engine braking, which helps slow the motorcycle. So, the normal result of rolling the throttle away is some deceleration rather than speeding up. Rolling the throttle toward you would do the opposite and speed you up. A throttle lock is a mechanical failure, and stalling is a separate condition that doesn’t describe the typical effect of simply closing the throttle.
