Close Ratio
In a transmission it describes the gear ratio of a gear set that comes closer to the gear ratio of the following gear set than the OEM gear set.
Example: The original gear ratio for the 1st gear in a Big Twin 4-speed transmisssion is 3.0:1. Andrews offers 1st gear sets with gear ratios of 2.44:1 or 2.60:1. These values are closer to the stock 2nd gear ratio of of 1.82:1.
In practice, this means that the drop in engine speed from first to second gear is much lower than with the original ratio (25% or 30% compared to 39%). The Andrews Close Ratio Set is not quite as good as the original in terms of first-gear acceleration, but it has the advantage of achieving a higher speed at the shift speed.
