The motorcycle death wobble occurs when the motorcycle handlebars and front wheel rapidly wobble back and forth. This motion or oscillation, quickly gets worse until the rider loses control. The death wobble can cause bad motorcycle accidents in which the motorcyclist runs off the road, or veers into oncoming traffic, or falls off the bike. At normal speeds this problem is usually caused by a maintenance problem that makes the steering unstable. All it takes for the death wobble to start is an irregularity in the pavement, a gust of wind, the rider.
