Optimum off-road-motor bike gear ratio?
Is there a gear ratio calculator or formula that can determine the optimal final low drive gear ratio for an off-the-road motor bike?, that will take into consideration;
-a total bike, motor, rider, and carry weight of 325 lbs
-7,000 max rpm
-40 percent max incline grade climb capability
-26 inch wheel diameter
