db Dirtybike Industries Sur-Ron Rear Sprockets

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.  These sprockets do 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.  Stock 48T Sprocket = 106L Chain 52T Sprocket = 108L Chain 54T Sprocket = 110L Chain 56T Sprocket = 112L Chain 58T Sprocket = 112L Chain 60T Sprocket = 114L Chain Note: We are substituting the Amped Bikes 54Tooth Sprocket for the DB sprocket at this time.  Designed to give more torque to the Sur-Ro
