Complete selection of Andrews transmission components. Why Andrews transmission parts? Andrews gears and shafts are made from stronger-than-stock materials. They have heat-treated and polished surfaces where necessary for smoother and faster shift operations, which results in much longer durability of all transmission components. It's hard to believe there is such a big difference between Andrews gears and others until you ride a bike with these products installed.

2.24:1 / 1st Gear - 1.65:1 / 2nd Gear Combination Set

If you want peak RPM thru the quarter mile, this gear set will provide the super close ratio shifting to handle it. For all engine sizes.

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.
