It is important to have the correct gear ratio for the tire size for proper operation of your clutch or torque converter. A improper gear ratio will make the clutch or belt slip and cause damage to the unit very quickly.

To determine the gear ratio necessary for your go kart or mini bike you must know the limit of your top speed.  When using a clutch to drive your go kart the top speed on flat terrain is 35mph, if the terrain is hilly or the weight of the driver is high the top speed should be 25mph.  Mini bikes work best with a top speed of 25mph for all terrain.

When using a torque converter with a go kart you may go as high as 45mph on flat terrain and 35mph on hilly terrain.  For mini bikes 35mph is the top speed when using a torque converter.

Use our calculator below to determine the top speed and gear ratio for your tire size.  Input the tire diameter, highest engine rpm,  number of teeth on your clutch or torque converter jack shaft and the number of teeth on the axle sprocket.  If you go higher than the recommended mph then the possibility of excessive slipping of the clutch or belt may cause early failure.  Changing the tire size will dramatically change the top speed so if you are going to a larger tire size you must correct the gear ratio for proper operation.
