Tank Slapper

A tank slapper is a dangerous situation where a motorcycle's handlebars violently shake back and forth, often hitting the fuel tank, causing the rider to lose control of the bike.

This frightening event gets its name because the handlebars literally "slap" against the motorcycle's fuel tank during the violent oscillation. Riders also call this phenomenon a "speed wobble" or "death wobble" because of how scary and potentially deadly it can be.

Tank slappers typically happen when the front wheel loses proper contact with the road surface. This can occur when hitting bumps or potholes at high speed, landing hard after the front wheel lifts during acceleration, or when the motorcycle's front end becomes unstable due to mechanical issues.

Several factors make tank slappers more likely to occur. Poor motorcycle maintenance, especially worn suspension components or loose steering parts, increases the risk. Incorrectly adjusted suspension settings can also contribute to front-end instability. Additionally, riding with a death grip on the handlebars can actually make the wobbling worse.

If you experience a tank slapper, the key is staying calm and avoiding panic reactions. Loosen your grip on the handlebars immediately, as fighting the wobble often makes it worse. Grip the fuel tank tightly with your knees to help stabilize your body position. Most importantly, don't suddenly close the throttle or grab the brakes, as this can make the situation more dangerous.

Many experienced riders recommend maintaining steady throttle or even slightly accelerating through a tank slapper, as this transfers weight to the rear wheel and can help the front end regain stability. Some motorcycles come equipped with steering dampers, which are devices specifically designed to reduce the likelihood and severity of tank slappers.

Prevention involves regular motorcycle maintenance, proper suspension setup, and smooth riding techniques. Always ensure your tires are in good condition and properly inflated, as tire problems can contribute to front-end instability that leads to tank slappers.
