Thanks for the videos  [thumbsup]

You still turn in too soon in most corners. More when the speed is high, better when it's slower. "Smooth is fast"  [Dolph]

Tnx, glad you like videos.....
I know, kind a rather turn sooner, as do not want to be too late in corner and go out from road....! Agree that smooter is faster, but i am nit racing against anyone.....

What Stopintime is saying is that you are taking most corners (especially faster ones) with Early Apex.

Mid, Early, and Late Apex








This probably helps to visualize what he's telling you.





The red line, which is early apex, is what you are doing.

On the track, the downside of early apex is slowest corner exit.

On the street, the biggest problem with early apex is that you will run out of available space on the road (= your safety margin) toward the end of the corner.
Look at the picture again, and imagine there's a oncoming vehicle, and the driver / rider thinks and behaves the same way as you do (early apex).
Or, there's construction going on, crushed bike, oil or sand patch . ...

As you said yourself, you are not racing against anyone, then ...

slow down at corner entry.

Beginners (almost always) do early apex, because of fear. (" I'm not gonna make that corner if I don't start cornering process early".)

Not so beginner riders do early apex when they start / try going fast, carrying too much corner entry speed.

If you feel uncomfortable doing (trying to do) late apex, then, you are going into the corner too fast.

THE ONLY ONE ADVANTAGE of early apex is, on the track, when you are trying to outbreak someone at the end of the straight line, then block his line toward corer exit (as you inevitably will run wide).

There's NO ADVANTAGE doing early apex on the street.

Going fast, start turn-in early, you are only increasing the chance of getting sideswiped by oncoming car.





That's what Stopintime meant.

@S21FOLGORE:

Only hat down for that post. Whery helpful and taken only with positive. Will think about that or even  better, take some  track day academy day.......!

There in second photo.....the green line.....on my opinion, you sooner become without space, pass the middle line if (too)faster in corner.
I am cutting only turns which are clearly visible.....

I ride for 4 years....that's my 5 season....with approximately 8-12.000km per year


Kind Regards

Trying to practice the tail braking in corners.....

On my opinion, the yellow line would  be perfect




S21FOLGORE

Well, it is great that you think about riding and practice when you are actually riding out on the road.
(A lot of people just,... ride without thinking, as if they believe rational thinking has nothing to do with riding motorcycles.)

That said, the yellow line you drew is NOT ideal, and NOT going to happen unless you are going really slow.

The first thing.
Why it's not ideal ?
Because you get in inside of the corner too early, you place yourself way too close to the center line in left turn (in US, and where you drive on the right side of the road), and you loose visibility in the right corner.
Getting too close to the center line in a series of tight corners is just an invitation for sideswipe accident.

The second thing.
You really can't do that. Why?

The first thing you need to understand is ...

Newton's 1st law of motion
(AKA : the law of inertia)


An object at rest remains rest, and an object in motion remains in motion with the same velocity
unless the object is acted upon by a net external force.


Velocity is a vector (magnitude AND direction),
Speed is a scalar (magnitude only).


A motorcycle that's turning around on the perfect circular line at constant speed is
accelerating.

(The situation is, the magnitude of velocity which is called speed is not changing, but the direction is continuously changing.

Acceleration is also a vector. The definition of acceleration is the rate at an object changes its velocity.
If an object is changing the velocity, it is accelerating.)

A motorcycle moving on straight line with no change in speed is, well, not accelerating.
An object (motorcycle + rider, maybe + passenger + luggage) is moving with a constant velocity,
and it will remain in the same motion (moving in the same direction with the same speed) UNLESS
a net external force is applied.

Okay, so that's the first thing you need to understand, IF YOU REALLY WANT to understand motorcycle cornering.
(Well, the logical side of motorcycle cornering. )

So why it is so important to understand Newton's 1st law of motion?
Because it's directly related to this subject that many, many riders misunderstand.

Centrifugal force doesn't exist.
Then, what force(s) are working on a motorcycle while cornering?

Off topic, but:

are you allowed into, and back from, Italy and Austria yet?
