DirtyBike Rear Sprockets Surron Ultra Bee

Add a larger rear sprocket and get better acceleration! This is a must for off road. Better acceleration, better hill climbing and longer run time with only a small reduction in top speed. 

DirtyBike Industries sprockets are OEM quality zinc coated steel sprockets with beveled edges for smooth chain engagement. 

Remember, It's always a good idea to replace the front and rear sprockets as a set to reduce premature sprocket and chain wear.
