Before telling how to properly hang in a corner, it would be nice to understand why this is necessary.
First of all, it is necessary for cornering at a higher speed than is possible without hanging, because while the center of gravity moves down and to the side.
Thus, balancing the centripetal acceleration requires a lower slope of the motorcycle. Or, in other words, with the same angle of inclination of the motorcycle in a bend, the speed in the bend will be greater than without hanging. You can read more about this in Lee Parks' book, Full Control. It explains in detail what forces act on a motorcycle in a bend and how hanging helps a motorcycle to go through a bend.
Ok, then the text should be read only to those who do not doubt the need for hanging in the corners. You can get this confidence by reading Parks or simply by taking my word for it. I'm certainly far from Valentino Rossi, but I also know how to ride a little.
In addition to reducing the angle of the motorcycle, hanging also gives improved maneuverability in the corner. At high speeds, the motorcycle does not suffer from excessive turning, so the main problem is to keep the turning line. Roughly speaking, it is always easier to straighten the trajectory of movement than to reduce the radius of rotation. When transferring weight to the side, this task is simplified - the motorcycle responds more obediently to the control when it is necessary to increase the tilt angle even more. Also, the knee set to the side, at speeds above 150 km / h, starts to work like a sail, which also helps to turn in high-speed turns. In addition to this and show-offs like “I'm riding like MotoGP”, the knee set to the side works as a limiter for tilting the motorcycle. Even with quick control, the motorcycle stops tilting when the slider hits the asphalt.
Now in more detail ... First of all, you need to start hanging up before the turn, when the motorcycle is still traveling relatively vertically. Any transfer of the body directly in the turn is a rather dangerous action. In addition to changing the center of gravity, directly when hanging, usually the arms on the steering wheel are tense, which leads to taxiing errors. The only thing that can be justified in a turn is a “weighting”, i.e. even lower damping when you need to tilt the bike directly in a bend even more.
How much do you need to hang? In theory, the stronger, the better. But in practice, when hanging, it is required that the hands on the steering wheel are relaxed, you can not hold on to it. Those. with proper hanging, you can greet oncoming people in a turn with your left hand, show indecent gestures or touch the asphalt (not recommended - you will have to change gloves). Therefore, each, based on the height of the saddle and his height, must find on the motorcycle the maximum possible displacement at which you can sit on it without clinging to the steering wheel. Usually this shift in the saddle is “half-assed”, with the knee resting against the gas tank, and the outer leg presses on the bandwagon. I note that this is not a “weight transfer to the outer bandwagon”, but simply the tension of the leg muscles, in order to get a stronger grip on the gas tank with the knee.
So, we rush in a straight line ... We brake ... We rise on the steps ... We hang our ass ... We cling to the gas tank with our knees ... We put our knees out ... We tilt the motorcycle and go through the turn ... It seems to be simple, but not quite right. The point is to minimize the tilt of the motorcycle in a turn, to hang only your ass is not enough. We look at the picture ...
The angle of inclination is about 45 degrees, actually a little more, because asphalt is tilted inward to turn. Rubber moderately road, not for racing track: in front of the ContiForce Max, behind the Michelin Pilot Sport. The green line shows the axis of symmetry of the motorcycle. In this case, the upper body is located quite close to this line, because when shooting, the task was to show a strong tilt in the turn. If the body is shifted even more to the side, then when drawing a slider on asphalt, the slope of the motorcycle will be less (a possible slope is shown by a yellow silhouette). A stronger displacement can be achieved by moving the steering wheel to the side. Those. one arm is extended to its full length, the body is tilted, the helmet is located near the steering clip — it is on the inside of the turn. In short, you need to reach with your head towards the handle of the steering wheel. Such gymnastics, however, is impossible without a steady fit in the saddle, which should be trained first of all, because the hands on the steering wheel should be relaxed.
What gives the correct hanging? The center of gravity of the motorcycle / motorcyclist system is now even lower and even further away from the axis of rotation of the wheels. The motorcycle is tilted at a smaller angle at the same speed. And this means that now we can increase the speed, and accordingly, the angle of inclination to the previous value. The motorcycle was already leaning at this larger angle, and no loss of grip was observed. Now you can slowly remove the knee and think about acquiring sliders not only on your knees, but also on your elbows. :) However, doing this on public roads is not the best idea ...
When tilting the motorcycle at large angles, you must also pay attention to the correct position of the legs on the steps. If everything is simple with the external footboard, the asphalt is far away, then everything is not so simple with the internal footboard. The foot should not rest against the footboard with the heel or midfoot, otherwise there is a danger of properly hooking the asphalt with the toe of the foot. How painful it is without racing boots I will not tell, but even with them it is quite unpleasant. The foot should rest against the inner footboard with the toe, the foot can be placed on the gland-limiter near the footboard. There is also such an option when the toe of the boot presses perpendicularly to the very edge of the footboard, as I do, but at the same time sliders on the boots are often stitched.
How to start drawing asphalt with sliders?
1. Send nah those who say that it is very simple.
2. Train hanging on a stationary motorcycle.
3. Always remember that the hands on the steering wheel should be relaxed. You can’t hold onto the steering wheel.
4. Remember that the throttle stick in a strong tilt is dangerous not only when opening, but also when closing. The gas must be even (slight acceleration) at the apex of rotation, so that it does not happen.
5. This is scary ... You need to convince yourself that on even gas the motorcycle will not fall at an angle smaller than the exposed knee will allow.
Next, you need to find a relatively empty road, take with you sane friends who will look at the workout from the side and point out errors, and not see a free circus in the workout. On this road you need to choose a fairly sharp turn, which will be clearly visible, and train there. The price of an error when training in a sharp bend is less, because will have to fall at low speed. Ideally, the turn took place “with the knee” at a speed of 70-100 km / h.
The training itself is unpretentious to disgrace: we pass a turn at that speed, which is not scary. This will avoid the mistakes dictated by the panic. Then we begin to increase the speed of entering the turn each time by 5 km / h, until it becomes scary or draws the asphalt slider. If it’s scary, then enter the turn at this speed until the fear is gone, then move on to increase speed further.
