Rear Sprockets are offered 43, 45, and 47 tooth configurations.
Please be mindful of your gearing configuration when making changes...
If you'd like to get a better idea on ratios, we recommend checking out GearingCommander.com
The list below is a full application guide for every model that our rear sprocket will fit. We will be adding these kits over time.
If you currently have a 520 conversion and need just the sprocket, please contact us directly.
Units may have a 3-5 day handling time during the initial launch.
Please Note: These are not stock width sprockets, they are 520 Conversion Kits. You're purchasing a Toce Rear Sprocket, Max X RK Chain, and Driven or Vortex Front Sprocket
All the Technical Stuff
You can view a picture of the von Mises yield criterion stress analysis below
The finite element stress test analysis for 9000 pounds of chain tension (100 link 1100cc chain max tensile strength) results in a maximum stress level of 170,000psi
Our material's yield strength is 230,000psi.
Meaning the chain would have to handle 30% more pressure per square inch prior to any deformity of the sprocket.
The tensile strength of the sprocket is 255,000. The catastrophic failure point is this margin...
