Sorry for sounding stupid, but what does this mean? I've been in the aviation business for many years and built drones and full scale aircraft. When you know your CoP, are you trying to balance the weight of the vehicle or motorcycle to match that location?
I use the example of a weather vane as it uses extreme CP/CG ratio to work.
If you think of a traditional weather vane, you have a large weight on the front (arrowhead, chicken head....) and a large tail of some sort on the back end (arrow feathers, chicken tail feathers...). What is happening with the weather vane is that you have the weight of the arrowhead (CG) at the front and the aerodynamic drag of the feathers (CP) at the rear. In the arrangement of a weather vane you want the arrow to point into the wind. The further the CG is ahead of the CP the easier it is for the weather vane to point into the wind.
Now, if you have a calm still day and the wind suddenly picks up on the rear of the vane it will snap around to point into the wind. A smaller example of the same principle is the arrow. Point (CG) in the front and the tail feathers (CP) in the rear. With the ratio that it has it helps to hold the arrow in a straight line. If you drop an arrow tail first from enough height it will turn around and fall point first.
The problem with extreme CP/CG ratios is that on a vehicle (car, rocket, motorcycle...) with extreme ratios it will want to weather vane into the wind. Using toy rockets as an example if you make it nose heavy with big tail finds it will launch and immediately turn into the wind. If you want to get it to track straight or close to straight you want a small ratio between your CP/CG. In model rockets about one caliber of the rocket body (diameter if you will) between the CP and CG is good. This will keep the pointy end forward and reduce the effects of the rocket wanting to weather vane.
Same thing for a car. If you have a wide ratio crosswinds will affect you more severely. If you have a reversed ratio (CP ahead of CG) you will have the car wanting to turn around when the aero becomes strong enough to affect the vehicle.
In your weight and balance sheet on the airplane you are actually calculating the ratio of CG/CP. The main difference is you are also calculating the force of the elevator to be able to maintain leverage over the pitch of the aircraft based on weight. The vertical tail and elevators on the airplane are sized so that at MTOW the CP/CG ratio is in check. In aviation terms it is more important to maintain the weight and balance so that the elevator can maintain control since the CP/CG ratio is already engineered into the calculation. It is likely you can't move the CG rearward enough to effect the ratio without first being outside the balance/elevator control envelope. You would likely just climb vertical at V2min into a stall and end up on your lid if you could.
