We designed this sprocket to replace the 42-tooth stock sprocket that comes with our Super Motor conversion kit. It gives you a significant amount more torque and less top speed.  With this sprocket your bike will have a top speed of 28 mph which is within legal limits of most states for an electric scooter although we still do not recommend or condone riding the Sur Ron on public roads. The 54-tooth sprocket will give you incredible torque and wheeling power way beyond what the stock Sur-Ron has. 

The 54-Tooth sprocket will require changing to a different sized chain unless used with the Luna Sur-Ron Super Moto conversion kit, in which case the stock chain will work.

If you have an X Version you will need to add additional chain found here
