Hi John,

Firstly to set up the model consider a front wheel rotating on a stub axle. We will divide up the rim into 360 degrees and say there is an out of balance mass of 5 grams on the inside edge of the rim at a position of 0 degrees. to statically balance this arrangement you can add a mass of 5 grams to the wheel at 180 degrees. But the out of balance force is a function of the distance of the unbalanced mass from the kingpin. So unless you fluke it and add the mass at the same distance from the king pin you will not acheieve a dynamic balance.

Having said all of that, if you run the fronts right out then the you may well improve the dynamic balance by statically balancing. If the difference between where you should put the additional mass and where it is acually put is small compared with the distance to the kingpin.
