copemech Posted March 27, 2013 Report Share Posted March 27, 2013 No! I do not believe I have seen these ratios published by any of the mfg. I suppose if one wanted to calculate it, he would need to start turning the crank and counting the rotations. The final drive ratio is easy division, yet overall would include, primary drive, trans and final! Quote Link to comment Share on other sites More sharing options...
