Original Equipment Manufacturer's "OEM" size sprockets are the calculated "Happy Medium" of off the line acceleration, roll on's, and reasonable high speed engine rpm's with the least amount of compromise on either top end or low end acceleration.
Adding Quicker Acceleration ratios will reduce terminal top speed and add engine rpm's to top gear cruising speeds.
Speedometer re-calibration may be necessary with other than OEM ratio sprocket sizes.
