 Mechanical strength testing of custom Luna Cycle 60-tooth sprocket in CAD

 

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.

The Sur-Ron uses a 420 sized chain and you will either need to add links to the existing chain or buy a new 420 chain of the correct length

The Sur-Ron X uses a a 420 O-ring chain and it's not compatible with the supplied extension, you must either replace the chain or add a proper o-ring extension to your o-ring chain.

We will be posting top speed reports soon of this sprocket on both Super Moto bikes and Mx Bikes.
