Over time I’ve made these for my own use (Adapted from John Denman’s original CR125/CR80)
Use these to calculate various things such as top speed for a given gearing/RPM, RPM drop between gears and more. Make sure you update the RPM range for your specific engine\tune and verify the tire circumference for best results.
They are mostly older models (Figures since I made them around 2013 ish), but I did add the SSE 175 and RoK recently.
