High speed wobble for a motorcycle can be prevented

  1. by further increasing the speed of the vehicle.
  2. by slowly closing the throttle without applying brakes. ✓
  3. by shifting the weight of the body to one side.
  4. by suddenly applying brakes and balancing the vehicle.

Answer: B. by slowly closing the throttle without applying brakes.

You should slowly close the throttle and let the motorcycle slow down without applying the brakes.

Why this is the answer

The motorcycle handbook's wobble procedure says that if the front wheel starts shaking at high speed, you should hold the handlebars firmly, avoid fighting the wobble, and gradually close the throttle so the bike slows down. It specifically warns not to apply the brakes, because that can make the wobble worse, and never to accelerate. Slowly closing the throttle without braking is therefore the action that matches the handbook. Pulling off the road once you can stop is the next step.

Why the other answers are wrong

Remember it

If the front end shakes, think: ease the throttle, leave the brakes alone.
