[BIKE] KTM RC8R *PHYSICS UPDATE*

[Vini]

it is about using progressive throttle and before the point of slide

Could you explain what exactly you mean by that?


This video was still done with the first Physics update ('v1.1' so to speak).
So, in v1.3 it works the same way.

[rodney007]

I mean by controlling your throttle progressively rather than just jamming it fully open on every corner exit

I like the change made to the reflectiveness of the windscreen. Was wondering if a slight tint of color could be added? Maybe a little blue or grey. Right now sometimes I can't even see it's there. In the menu screen where you can pick the bike the wind screen has a slight tint to it. Thanks.

With it being a superstock 1000 and not a grand prix bike.. Id like a touch more grip from the rear and maybe back the sliding off a little bit? I wanna see the rear tyre dig in and squirm around on the power! 

[HornetMaX]

as you may know i keep banging on about adjustable steering dampers lol so im intrested along those lines...

That's easy to play with (editing the bike's physics files). From a past exchange with Piboso:

Q: In the bike.cfg file, what are Damper and DamperPower in the steer section ? Probably related to some sort of steering damper, but how should we interpret them ?

R: Steer damper. Damping torque = Damper * (steer speed ^ DamperPower)

id be carefull not to spend too much time doing it though rodney because nobody knows when beta6 will appear.. or what it will be like!
this ktm might be completely different with beta6.. just a heads up really, i know its none of my buisness..

Sound advice, IMO.

Engine:
Engine has been rolled back and top speed corrected

Any reason for not putting the real values for engine (and transmission) ?! It's a 10min job to find them on the web and once done it's done.

MaX.

Well, it was possible before. It was just really really hard, too hard in my opinion, especially when you think about the fact that in MotoGP/SBK they are sliding the rear out of every corner and if they had no tyres or fuel to worry about, it would smoke just as much as it does in the GPB KTM videos.
I actually think that holding a long but 'non-smokey' slide (from the apex on, just as they do in MotoGP) is still extremely hard with the KTM.

Yeah I agree. I'm playing Devil's advocate here to a certain extent. Deliberately.  In my honest and humble view I think the slides in gpbikes from my admittedly limited experience are as much caused by "momentum" through the bend as they are/were caused by throttle input. I do not mean to sound outspoken in saying that but that is my honest take on how things feel/felt. I also agree that in modern era racing with all the electronic assistance provided real life racers are sliding pretty much all the time to a limited degree. It's all part and parcel of the necessary technique and approach to modern racing to get a motorcycle round a track as quickly as possible. I just wasn't feeling this in gpbikes to be honest and I do not wish to offend anyone in saying that..I really don't. I'm just trying to be honest. And I fully accept in saying this I am voicing only my own opinion.   

My biggest area of consideration in this respect are the 500cc 2-stroke grand prix bikes. Again in my personal opinion the slides were more "momentum" slides than throttle induced slides. But this is a much more delicate and precisely defined aspect of power-sliding than it is with the modern 4 stroke bikes. It is as we all know a much, much finer edge with the 500s. Rear wheel power sliding/rear wheel steering on the "beasts" should be very, very challenging to access and very, very challenging to maintain and execute properly. I agree and bow to the expert opinion of the likes of Eduoard et al in this respect and I agree with them..but in my honest & humble opinion rear wheel steering should be slightly more accessible than it currently is on the 500s in gpbikes. But that is just my own personal opinion and I'm sure others might disagree with me on this.   

Returning to the modern 4 strokes the crucial thing to my mind is that sliding just for the sake of sliding is not the answer to fast lap times. It also burns your rear tyre out more quickly and puts some stress on your front tyre also in terms of wear. It's faster not to slide (at least not to slide excessively) the majority of time. But it is there if and when you need it. That's my take anyway. So in races using this physics model or a very similar one you would not be doing yourself too many favours at all by power-sliding too much..

Overall, with limited track time and less experience than you guys on gpbikes generally, I prefer version 1.3 if I am honest. With a few tweaks..

you mean 10 seconds...
Working on physics w/o using the real data is a waste of time...jm2ct
....and out......

I have to agree, why would the real engine values be changing from one version to another? Those should always be fixed to the actual bike values. Then the rest of the bike or tires should be adjusted around that to get the desired effect you want. Just putting in your own values for a well documented engine seems kind of odd. Seems more like personal preference how you want it to feel more then what the actual bike would be.

How do you know that GP-bikes correctly simulates a real life engine curve?  its ok I am sure its just like real life

I feel we have accomplished what we wanted here. 5B feels very bad to me without these changes (ridiculous wobble/erratic high speed wheelie etc)

So on this we end any more physics advancements.

Thanks for the input guys and whom helped test will be informed to help us on our soon-to come future projects :-)

i.e this one (almost done)

Awwww yis

I'm pretty sure your going to need a update again for beta 6. Since the Wobble only came up in Beta 5/5b. Wasn't in Beta 3-4/4b. So it's a known bug.

What about throttle steer? do the others have that? Answer: No... lets see 6B if Piboso follow

[Klax75]

To be honest with DST yes, all the bikes do to a certain extent.

Ok Maybe you should make something then? 

lets all go DST

[Klax75]

Anyway, good work on the bike.
