Guaranteed Asset Protection Insurance (GAP) is designed to protect you from a hit in the pocket if your motorbike is declared a 'total loss' or write off by your bike insurer.
If your motorbike is deemed a total loss (typically because of an accident or theft), insurers will only pay you market value for your motorbike at the time of the incident; therefore, because your motorbike will depreciate in value over time, there is likely to be a “gap” in the financial settlement between what is paid out by your bike insurer and the amount that you purchased your motorbike for.
In the case of bikes that are purchased with finance, shortfalls are potentially made bigger, in turn meaning that you face a double hit by having an uninsured liability and no motorbike to enjoy or use for essential journeys.
