[Long, fast corners, how?]

This is a very broad question. The answer will depend on a variety of factors about the corner: radius (and whether it is increasing, decreasing, or staying the same), camber, surface (grip, bumps, etc.) so I am not sure what sort of answer you are hoping we can provide.

If the radius of the corner is increasing, and the camber is either unchanging or getting more favorable, you should be able to accelerate through the corner, however if the radius is decreasing and/or the surface is going off-camber, you may have to be slower later in the corner instead of faster. A corner with a crest in it may, as you mentioned, lighten the bike as you go over it and may require a pause on the throttle to maintain traction.

My recommendation would be get ahold of a copy of "The Soft Science of Road Racing Motorcycles" and have a look at Chapter 2, which includes info about how to sense traction for yourself, and Chapter 3, which talks about making a plan for how to ride a turn and how to adjust the plan to fine-tune it, and Chapters 9-10 that get into how to increase your speed through corners, and specific riding styles and how to make the best use of the strengths of your specific motorcycle and your own riding skills. There is a lot of information about how to handle certain types of turns, adjustments that can made to line or throttle and the effects those adjustments will have, and a ton of other information I am sure you will find very helpful. 

Excellent, thank you for pointing me to the chapters.

Very long corners have a huge radius by definition.

The lateral cornering forces that make you lean your bike are inversely proportional to that radius.

For that reason, the necessary lean angle should be moderated and your tires should be far from the limit of traction, unless you speed is too high.

You are right - but only partially I think. Lateral forces are not big, however you are potentially under full throttle. So question is, how much more force tire can handle. On video I've posted in time 1:27 it's not visible very much, however that corner is even "over horizon". So in the middle of the corner you are lean, under throttle, and lighten.

By default I'm pretty defensive so in reality with my FZ8 with smooth throttle I'm safe. However I would rather not highside at 130km/h 🙂

Hi all, what is the best technique to go through very long fast corners.

Full throttle and cornering doesn't look like best idea (I would expect something like higher risk of highsider), however I'm still a novice, and maybe with given lean angles and this is not an real issue.

To be more concrete please check this video from Most circuit https://www.youtube.com/watch?v=mJjI5ltEFiI there are at lest three such corners - time 0:34, 1:00, 1:27. (This is not my video :-)

Thank you.
