CLOSE RATIO VS. STOCK RATIO Stock ratio transmission gears for 5-speed Big Twins were developed by Harley-Davidson ® engineers for all of their models. An overall internal gear ratio was chosen to work well with everything

from a Dresser to a Dyna™ Super Glide. This stock ratio (3.21:1 ratio low gear) works fine with the approximately 69 horsepower that the stock Harley Davidson ® motor makes.
