Midwest Mini Mods 54T 428 Rear Sprocket for razor wheels

Bolt-on 54 tooth 8.75in rear sprocket for Razor MX, SX, or RSF.  This mod allows the use of the much larger and stronger 428 chains (sold separately and elsewhere) that will eliminate the binding that the links of the T8F are prone to. 

***The factory chain tensioner will not work with 428 chain, modification will be required.***
