Are you familiar with the term “counter steering”? Counter steering is the ONLY way a motorcycle will turn. It is something you have been doing since you learned to ride a bicycle but understanding the process will make you a MUCH better rider.
At very slow speeds you steer a motorcycle by turning the handlebar in the direction we wish to go. You can only do that at speeds of less than about 5 MPH. At any higher speed you do the exact opposite, whether you realize it or not. For example, assuming you want to turn to the right, you are actually pushing on the right handlebar. This results in the front wheel leaning to the right and, as a result of the lean of the wheel, a turn to the right. This is counter-steering.
There are many forces acting on the motorcycle when you initiate a turn. The wheels of a motorcycle act as big gyroscopes. That is why a bike becomes more stable with speed. When you begin a turn you are displacing the gyroscope (front tire) and the force is exerted in predictable directions. The phenomenon that turns our dirt bikes is called Gyroscopic Precession. This is what happens when a lateral force is applied to the axis of a spinning gyroscope. The spinning gyroscope translates the force vector ninety degrees off the direction of spin. So, if we try to turn our front wheel to the left, the force we use appears as a lateral force forward against the axle on the right side and this is translated into a force that tries to lean the wheel to the right. Similarly, trying to turn the wheel to the right results in the wheel trying to lean to the left.
With this knowledge you can understand that the weight on the pegs doesn’t CAUSE the bike to turn, it simply distributes the weight of the rider in such a way as to not fight the forces acting on the bike. In other words weighing the outside peg assists the gyroscope in turning the bike. It also keeps you in an aggressive stance so you can quickly adjust your weight when accelerating out of the turn.
That’s all I have for now.
