The V1 and V2 keys switches will work on all Pro Dirt Bike models. However, if you are ordering this kit to replace a missing key, if you buy the same version, then you don’t have to swap out the switch. The silver keys are universal and work in the same V1 switches and the black keys are universal and work in the same V2 switches.
