To bend without rubbing steps …
The other day, I happened to have a chance to run the circuit with a “neo classical” type bike. Upright liposi on narrow tires. Originally not a model for the circuit, it feels good to enjoy ultra-fast tooling in a big mood.
However, I noticed that I rubbed the steps gently during cornering in the meantime. Although it is not so much that it is running on a public road as usual, at a circuit where the speed range and the grip of the road surface are also remarkably high as expected, the load applied to the car body during cornering also becomes large, and the suspension The bank angle also gets deeper, and as a result the step hits the road surface.
In this state, the bank sensor wears away and it wears out, so I was forced to devise various ways to ride on my own. By the way, the bank sensor is a protrusion attached to the bottom of the step bar, and in modern sports bikes there are many types that can be exchanged because they are screwed in only that part.
As usual, trying on the “hang-off” style with its waist shifted to the inn side, it is not such a motorcycle as expected, so I will not come over it. On the contrary, the banking angle becomes deep for a moment due to the momentum when the weight moves, which is the opposite effect.
Now, repeating the trial & error as to what it is, when finding it conscious of the form which put only the upper body on the inside side big enough without shifting the waist or opening the knee, that is, “lean in”, the step is also rubbed I knew it was going to bend slowly, I also enjoyed the pace going up. Even on the same circuit, the way you ride depends on the ride model.

MotoGP also recently learned
For lean-in, there is an effect that the turning force can be strengthened while the bank angle is made shallow. While the hang-off is weight transfer centering on the waist, lean-in can demonstrate the effect of large weight shift by putting the upper body into the inward side of the head.
There are also many people who came here with pins. Looking at MotoGP which is the highest peak of motorcycle motor sports, either Marquez or Rossi, we can see that the recent GP rider is cornering rather than hang-off. That’s because the bank angle has become deeper as there are no gaps between the waist and the knees due to the remarkable performance improvement of the machine and the tire and the evolution of the electronic device.

It is said that the bank angle of recent MotoGP exceeds 65 degrees and it is not known whether this is already sleeping or is falling (lol). In other words, it is a lean-in as a struggle to withdraw further turning power from a bike that can not be physically put down.
By the way, until the 1990s when the 2 st 500 cc was a flower form, the orthodox hang-off (which can also be said to be the old style), the head of which was greatly shifted to the in-side while leaving the head near the center, was mainstream, but this is the mainstream of machines and tires It is because the performance is developing and I can not rely on electronic devices etc. In other words, it was a form necessary for the rider himself to constantly control an unstable machine.

Looking backwards, I miss the figure of Legend of former years such as Kevin Schwantz and Mick Doohan who bent their backs to “Ku character” and set up for somewhat upright.
What is the secret of the form of a police officer
Although the talk diverted, lean-in as a worst-case measure can also be seen near here. It’s a riding staff’s riding style.
Of course patrols are always dignified, but their cornering form on a time trial, such as a white-bai competition, is leaning like it pushed for. A unique form in which the upper body is put on the side of the big inward as if to thrust in from the shoulder. It is what is called “whiteboard riding”.
•Alpinestar members are compatible with safety margin and turning power by making use of unique lean-in form
The reason is that if you ground the car body including the step with the convention rules, it will be greatly reduced. What lies behind it is that the Cruisers are required to carry out their duties safely and reliably under any circumstances. They are heavy heavy wheat wearing touring tires and they run on rain or unpaved roads, so to speak, they are specialists on public roads. In other words, as a model of safe driving you can not do how to rely on the bank angle, it is because you can not do.
Aside from that, the lads of the whitebait run on rainy days with almost the same time as the dry road. There are also lean-in born from such special circumstances.
Although it became a rambling story, the form is inevitable, it means that it is required to run according to motorcycles and circumstances. There is lean-in as one means of that, by effectively using it you can achieve safe and enjoyable riding.
