I had this issue when I started playing GPB.

It was my trajectory (taking the turn a bit too early). Since I discovered it, no problems!

Right, closing the trajectory too early can lead to this (I think that's because you will then be on max lean angle right at the point where the track slope changes more).

As it has been a while since I've been on the 125cc, I'll try to do a few laps tonight to double check. But when I was using the 125cc a lot, I definitely had zero issues on Victoria, so it's just a matter of practice. GPB is all practice. And practice. And then practice again. After that, it's all practice.

On other tracks however, the problem is much much worse, but it's a known problem and is most likely due to a mix of "bad" track model and some GPB physics weirdness (Piboso is aware of it).
Some tracks are much less affected by this (e.g. Catalunya and Mugello by SaintWest).

@C21: Xbox 360 pad + xinput.dll = you're all good to go

I have this issue in Phillip Island Turn 10 too (can only play the demo right now), especially at the right hander after the downhill......and i thought it was a fault of my riding style....now i am aware it is a "design" fault....good to know, it destroys several of my laps at this special corner....and i didn´t know why until now 

With the  125cc bike the issue is probably worse and it is definetly present on *other* tracks. But notice that that specific corner on Victoria has baffled many riders until they day they realize they were doing something wrong (me included). Victoria is a nice track, there are no kn ow behavior issues on it (as far as I know).

1st of all, which joypad are you using ?

How it is calculated in GPB is simple: engine RPM, gear ratio, transmission ratio, tyre radius (outer).

What you are basically asking is to factor in the other factors (aerodynamic drag and rear tyre slip).
I suspect your tables only keep the aero thing into account (and in an approximate manner).

But is it a big deal ? I mean, usually you go out with the default gearing, a couple of laps and then you've a good idea of what the right gearing should be ...

I say cut out all the riding aids and let's see how todays riders truly face up to the machines they are riding today.

Don't know ... motor sports have always been a test bench for research and innovation. You simply can't ask to go back to the era of "2t, no electronics, no carbon" just because it was (supposedly) more funny to watch/ride.

If a championship sole goal was to see who's the best rider, they should all compete with identical bikes (over time, to allow comparison of riders of different periods). But that's not the case.

And this season has been pretty interesting: I can't see how we could call this a "ruined sport".

I tend to think that some of us have a "romantic" approach (the famous "it was better before"). Not long ago I had a similar discussion with another GPB player on electric motorbikes: I let you guess my position

I think the gearing top speed is only a theoretical one, it does not include the aerodynamic drag.
Hence the real top speed you can achieve is lower.

This.
It also doesn't count rear tyre slip, that can be high even in 6th gear on a very powerful bike.

Exact. This is actually the thing that made the engineers think about the big bang engines: they were seeing unexpected differences in bike speed vs rear wheel speed (on long straights) and when they realized they were due to rear tire slippage ...

I'm not 100% to get right what he's saying (english is not my native language).

At 1:30 he says that "[the modern bikes] are not near as exciting and a lot easier to ride" (which is indisputable to me).

But right after he adds "I would say a little more difficult to go right to the lap time, cause there's a lot of grip. It doesn't bend and wobble and move around".

"The stuff that I rode, you took it to the limit was .. how you could hang on, you know".

[Journalist] "And you got a little bit of warning".

"Yeah. And the traction was anywhere close to what it is now".

"The warning system right now is really about as close I think you'll ever gonna get."

To me he means that modern bikes allow the rider to ride extremely close to the limit most of the time, as the bike behavior is more predictable and less abrupt.
To make a good lap today you have to be right on the limit a lot more than before.

Sort of "today it's easier to go fast, but harder to go very fast".

The traction thing may look strange first sight, but if your grip is lower, you automatically have to go slower.

One thing that is often forgotten by 500cc 2-strokes fan is that today's bikes differences come from many more things than the sole engine.
Tires are much much (much) better. Frames are incredibly better. Brakes too (probaly to a lesser degree compared to tires and frames).
And there's electronics: have you seen today's race in valencia ? On the main straight the riders were accelerating with the front wheel 10cm off the ground for like 600 meters.
That's not doable by a human (with that precision, on every lap): the bike accelerates as fast as the physic allow, no more, no less.

I guess that the general idea is that bikes from the 80-90s were more "gutsy": brave riders not caring a lot about broken bones.
Today the whole thing seems a bit more "sane", but when you have reasonably close bikes and riders, there's still plenty of show to look at.

P.S.
Don't put too much value in my "explanations", just my opinion: I may (may) have some technical understanding, but I've never put my wheels on a track, so ...

I think the gearing top speed is only a theoretical one, it does not include the aerodynamic drag.
Hence the real top speed you can achieve is lower.

MaX.

At the same time he says (if I got it right) that it's harder to make a lap time with modern bikes, because they have a lot of traction and because you get a "warning" only when you are as close as it gets to the limit.

I confirm !

I had to remove the 13.5beta2 files I had in my GPB directory (workaround), otherwise the screen was messed up.

Now we just have to hope AMD will not screw this once again in the future.

[DON'T]

One thing most people don't know: if you reinstall (the same version, of course) over an existin installation, you DON'T lose all your profiles, settings, stats etc.

MaX.

Try to reinstall, first without uninstalling.

MaX.

Which hardware do you have (GPU in particular) ?

GPU drivers up to date  ?

MaX.

let's animate ... Board walks very still

That suit looks familiar  ....

The english sounds familiar too ...

Err, there was a big "IF" in his reply ...
