I have a harbor freight motorcycle pit stand model number 65620. The wheels inner core broke one day falling to the ground just right. The wheel is nice and I wanted to save it so I made an insert to take the place of the now missing center. This piece fits in very snugly and fills the indentation in the wheel. Two are needed one for each side. The bushing from the center needs to be inserted into these after installation. I made it extra beefy for safety and it works flawlessly. I included a step file in case you need one in a different size.
