Large Rear Sprocket for Better Acceleration and Longer Run Time
DirtyBike rear sprockets are OEM quality zinc coated steel sprockets with beveled edges for smooth chain engagement. Designed for off road riders to maximize acceleration with a minimal reduction In top speed.
Sprocket alignment is easy with a Motion Pro sprocket alignment tool. Remember to replace the front and rear sprockets as a set to reduce premature sprocket and chain wear.
These sprockets require a longer 420 chain. You can just add a few links to your existing chain but it is always recommended to install a new chain when new sprockets are installed. The length of chain needed depends on what size sprocket you are using.
