Load transfer! 2)

Load transfer! 2)


Did you manage to smooth out the load transfer from front to back?
Are you holding the handlebar too tight?

handle grip

First of all, I would like to talk about moving the load to the left and right, and turning right or left by operating the steering wheel.

The load moves from side to side by operating the steering wheel, but the timing of this movement is important.
When the brakes are applied, the load is moving forward, but the load that is leaning forward in this way must not be moved backward.

When I release the brake (release the brake that I stepped on), I start turning the steering wheel, and it is very important to do this smoothly.

The center of gravity when the car is stopped is the center of the circle, and when the brakes are applied, the load (center of gravity) that has moved forward is the radius, and the load is moved to the "right" or "left" in a circular motion. Achieves smooth running.

When releasing (relaxing) the brakes, the center of gravity should not be as close to the center of gravity when the car is stopped.

If you can summarize this point well, you will get closer to comfortable driving.
This "front to right" and "front to left" load transfer is the story of the front half of the circle.

Next I will talk about the load transfer is "from right to back" and "from left to
In the previous part, "front to right" and "front to left" in a circular motion I
explained, but this is basically the same for curves, right and left turns.
I was talking about the harmony between"when to start turning the wheel and when to release the brake".

After releasing the brakes and shifting to the control of the steering wheel only, it is time to return the steering wheel, but when it is time to return this steering wheel, "start stepping on the accelerator and move the load backwards". 

Again, move it with the image of drawing a circle.
The movement of the load is an image of drawing a circle, "from the brake to the steering wheel" and " from the steering wheel to the accelerator" to operate.
"From the accelerator to the brake" "From the brake to the accelerator".
Moving linearly, but when performing these operations "Don't tighten your grip on the steering wheel".
If the load transfer when bending is smooth and in the same way as the image of drawing a circle, the ride quality will be significantly improved and the tire life will be extended.
If you can master and apply these load transfers, you will see a new way of

That's all for today.
See you in next blog!

Hello everyone ♪

Are you doing your best  "not to grip too tight" or "not to pry" the handle?

This time, let's talk about "load transfer".

It is easy to understand if you have a G-sensor (accelerometer), but the direction of movement of the car is a combination of three directions: front-back, left-right, and up-down.

The load moves backwards when accelerating, forwards when braking, to the left when turning right, to the right when turning left, and up and down if there is a gap.
This vertical load transfer must also be controlled to some extent, but in this article I will talk about the forward and backward load transfer.

This is about acceleration and deceleration, but also about acceleration by accelerator work, engine braking and foot braking.

First of all, the role of the engine brake is only to be used for a "smoothly shifting the load transfer".

When full braking from full acceleration, if there is no engine brake, the center of gravity will move rapidly from the back to the front, and the stability of the car will be impaired, and passengers will also feel uncomfortable. 
With some exceptions, the engine brake is used only for postural changes.
Yes, basically I don't use the downshift engine braking.

The reason why the accelerator is pushed when downshifting in a race etc. is because of "Speed = Gear X number of revolutions".
And to sharpen up the next acceleration.
At full acceleration and full braking, try to apply force only in the direction of tire rotation.

Do not tighten your grip on the handle when moving the load back and forth.
And don't pry it.

In the next article, I would like to talk about "Left and Right" and "Left and Right + Front and Back".

Don't grip too tight! ~ Four-wheeled vehicles version ~

Hello everyone!

Are you driving safely? Or are you driving like a maniac?

Whichever you do, it doesn't matter.
Let's drive in a way that doesn't bother others!

In this article I will talk about the method that I was taught to use to control the steering wheel during cornering and how to apply pressure.

 This is not a technique or knowledge to turn a corner quickly, but a trick for stable cornering.

I was taught this when I was 22 or 23 years old....

A few years ago, there was a story about a test driver of a car manufacturer in Japan in NHK's program "Professional".  

This test driver was talking about 'holding the steering wheel with three fingers'*.
The reason he said was "to feel the behavior of the car"
*Usually it's thumb, index finger and middle finger.

What I was told at that time was, "Don't gouge the steering wheel."

"If you turn the steering wheel while braking, there are places where it gets heavy.
When you turn the wheel while accelerating, there are places where the steering wheel gets heavier."

The tyres exert their force in the direction of rotation, but applying it laterally with the steering wheel increases the burden on the tyres.
"If the road surface is good, the tyre will do its best, but it will lose quickly, it will sag quickly.
In bad conditions, you lose grip.
If you let the tyres do their simple job, they will last longer and not slip."

If you drive with this in mind, you should not squeeze.
If you tighten your grip, you won't be able to feel the kickback from the steering wheel.
You can feel the behaviour that the cars dislike.

If this behaviour and load transfer can be done smoothly, the passenger will not get motion sickness.

If you can do this, your safety margin will expand.
