The three speed transmission provides a gear reduction of 2 1/4 to 1 on low gear and 1 1/2 to 1 on intermediate. The low gear ratio can be obtained by multiplying the high gear ratio by 2 1/4. Likewise, the inter mediate gear ratio can be obtained by multiplying the high gear ratio by 1 1/2.

How to Figure Gear Ratios

As a matter of information, the high gear ratio for any combination of sprockets may be obtained as follows:

Multiply the number of teeth on the engine sprocket by the number of teeth on the inside countershaft sprocket; then multiply the number of teeth on the outside countershaft sprocket, or clutch sprocket, by the number of teeth on the rear wheel sprocket. Divide the result of the second multiplication by the result of the first multiplication. This will give the high gear ratio. To obtain the intermediate gear ratio or the low gear ratio, multiply the high gear ratio by 1 1/2 and 2 1/4 respectively, as already explained.
