We sell the Razor MX650 freewheel separately and it is our item # FWM-120. The newer MX650 versions have a freewheel with four holes for the bolts to go through instead of teeth that the bolts fit between. Both types of freewheels are interchangeable with each other so the new version freewheel will fit the MX650 that you are working on.
We carry the FWM-120 freewheel on the Razor MX650 Parts page.

Can I buy the free wheel seperate? Its actually a sprocket that's sandwiched inside the other sprocket.....I'm not looking to buy a whole back wheel if I dont have to
