What is the weight distribution over the tires on a motocross bike with the rider standing on the pegs holding the handlebars. Is it 60% front 40% rear etc. I suspect its closer to 50-50. Granted the rider will have a significant effect as they lean foreward or back. For some reason the test mag articles never do this. It may be difficult to have a standard due to the riders effect. I do notice offset steering heads/ triple clamps and different length swing arms in the magazine adds. Whats the correct range for motocross racing for a given rider.
