What may cause a wobble in your motorcycle?

A wobble in your motorcycle can often be attributed to improper loading. When a motorcycle is not loaded correctly, it can shift the center of gravity or create an imbalance, resulting in instability while riding. This can lead to a variety of handling issues, including the infamous wobble, which may occur at certain speeds or conditions.

In contrast, the other options provided are not typically associated with causing a wobble. Formula racing tires, for example, are designed for high performance on race tracks and are not generally used on motorcycles meant for street use, which makes them an unlikely cause of wobble under regular riding conditions. Using premium fuel does not have a direct impact on the motorcycle's handling or stability. High speeds can exacerbate handling problems but are not a direct cause of wobble; rather, it's the underlying issues like improper loading that can lead to instability at any speed. It's essential for riders to ensure proper loading of their bikes to maintain excellent handling and stability on the road.
