![]() ![]() Note that in some braking areas that rear weight goes negative, indicating the rear wheel may be off the ground. This chart shows data for speed (black), total weight (red), front weight (blue) and rear weight (green). X=horizontal position of CG from front axle Using GPS longitudinal acceleration data, approximations can be found that show how the total weight is distributed when the motorcycle is accelerating or braking on level ground. The amount of weight on each wheel depends on a number of factors. Note that the acceleration and braking forces act on what we have designated the total weight of the bike and rider, which includes cornering forces. As the motorcycle accelerates, weight is transferred from the front wheel to the rear wheel under braking, weight transfers from the rear wheel to the front wheel. Now that we have looked at static weight distribution and also found how cornering forces add to the total weight of the motorcycle and rider, in this post we will show how total weight is distributed between the front and rear wheels. ![]() An approximation for front and rear dynamic weight can be determined from longitudinal acceleration and values for the wheelbase and center of gravity position. ![]()
