A motorcycle tool kit is a collection of essential tools designed for performing maintenance, repairs, and adjustments on a motorcycle. It typically includes items such as wrenches, screwdrivers, pliers, tire levers, a spark plug wrench, and sometimes a small socket set. The toolkit is compact and portable, allowing riders to carry it on their motorcycle for convenience during roadside repairs or maintenance. Having a well-organized and comprehensive tool kit is crucial for addressing mechanical issues and ensuring the motorcycle remains in good working condition.

This tool can be used to lock in place the variator pulley, and therefore the crank shaft, on a 139QMA or 139QMB GY6 engine. This means that the variator nut can then be easily undone and components replaced.

Please note that work on the drive train by an inexperience person can cause damage to other components, and work should always be undertaken by a qualified motorcycle mechanic where necessary.
