BMW goes one step further in the aerodynamics war with a surprising patent

Aerodynamics have always been important in the world of motorcycles. For many years, work began while more and more aerodynamic knowledge was acquired. In fact, already in the sixties, work was carried out relatively frequently in wind tunnels.

Then everything moved forward, but the aerodynamic war that we are experiencing today will be even more important for the evolution of motorcycles. Now, after making great advances in electronics and in the image and similarity of what happens in MotoGP, the brands are working hard to be able to take advantage of it even more and the key is aerodynamics.

Aerodynamics to improve grip

In this case, it is BMW that is working and developing an air channeling system, which would seek to achieve more grip in a place where, for now, the electronics cannot provide it: the front axle.

The transfer of weight and the fact that the traction of the motorcycle is only in the rear wheel always means that the front axle does not have the necessary grip. And there is no doubt that aerodynamics is serving to contribute to this.

In fact, for this reason, ailerons have been evolving in recent years. However, the dynamic characteristics of motorcycles mean that the spoilers do not have the same effectiveness as on a car and, in addition, their surface is also very limited because the motorcycles roll over.

So we have to look for ways to improve it and BMW has patented an aerodynamic system without spoilers, but which is designed to improve grip on the front axle and downforce. A system in which air circulates from one side to the other through two tubes. On the straight it would have no effect, since the air would enter at the same speed, but the advantage would come in the curve.

The advantages would only be appreciated in curves, especially fast ones.

At that point, as one part is more exposed than the other, the air pressure between one side and the other varies. On the side that is closer to the ground the pressure is greater than on the one that is not. As the ducts are crossed, the air flow with higher pressure would be diverted to the other side of the motorcycle, generating an aerodynamic force that would “glue” the motorcycle to the ground.

This is achieved because the tube, as the CycleWorld colleagues explain, would be larger in the entrance area than in the exit area. The channeling would cause the air to be compressed in order to push the motorcycle against the ground and thus be able to get the most out of the tire in the curve.

As always happens with patents, just because this idea is on the table does not mean that we will see it on the street. What does seem more logical is to think that if BMW goes ahead it would use it in its sportiest models, since this type of system is only efficient on motorcycles with fast cornering and in that, the BMW M 1000 RR is the queen. .
