If your motorcycle starts to wobble you should:

When a motorcycle starts to wobble, the best course of action is to grip the handlebars firmly and gradually close the throttle. This response helps stabilize the motorcycle by allowing you to retain control while reducing speed without abruptly applying the brakes, which could worsen the wobble. By holding the handlebars firmly, you maintain control over the bike's direction and stability, preventing further oscillation.

Accelerating out of the wobble can exacerbate the problem by increasing the instability and making the motorcycle harder to control. Gradually using the brakes is typically not advisable during a wobble since sudden braking can cause the front wheel to lose traction, thereby increasing the risk of losing control. Downshifting could also lead to increased engine braking, which might contribute to instability instead of alleviating it. Hence, the recommended action focuses on maintaining control and gradually reducing speed to regain stability.
