Release Notes
- replays and bike setups are not compatible with previous versions

- the rider lateral lean now affects the bike aerodynamics, shifting the bike's center of pressure

- Multiplayer voting has been changed:
-- the default vote when on track is No
-- spectators cannot start a poll or vote, except for bans and during "waiting" sessions
-- the poll creator is displayed
-- possibility to disable polls during races: https://forum.piboso.com/index.php?topic=26.0

- The "alternate" onboard views mode has now been added to the user interface: GP Bikes -> Settings -> Simulation -> Cockpit View -> Lock To Bike
- It is now possible to link the "Lean Heading" to the rider lean instead of the bike lean: https://forum.piboso.com/index.php?topic=15.msg103743#msg103743

- There should be less fps stuttering in testing mode and when hosting a race
- It is now possible to disable the dynamic track surface in testing mode, too: https://forum.piboso.com/index.php?topic=13.0

- It is now possible, on Vive / Index only, to modify the IPD, changing the world scale: https://forum.piboso.com/index.php?topic=5188.0

- It is now possible to change the direct steer parameters: https://forum.piboso.com/index.php?topic=28.0

- Added the Windows Taskbar icon


Modding
- The rear suspension simulation fix requires the physics data to be tuned, because it changes the spring rate at the wheel, unless the motion ratio is roughly constant around 2.
- The slipper clutch simulation and physics data have been changed. For reference, please check the stock M2 bike. However, please note that unfortunately the simulation is still not correct and it will be changed again in future releases.
- The chassis inertia of the stock M2 was too high. The parameters have been lowered to values that should be much more realistic. Correspondingly, the chassis flex damping had to be tuned.
- The maximum name length is now enforced.
- The dangling leg animation now uses the track bestline as a reference. Please make sure to create a proper bestline, that is also used by the onboard views for the "Corner Anticipation".
- For an example of replay camera linked to the swingarm, please check the stock M2 bike.
- The track timer is now limited to 1 digit for hours.

"launch control simulation"

We have a bike in b17 with this feature or is just supported for mods?


Reading the changelog Looks the best beta so far!

Thanks, PiBoSo and crew, I cut some good laps with the M2 and it feels good but still very little front end chatter so I'm just going to say it's all about the set up as I rode the bike with the default settings. I really enjoyed the new 05Assen and looking forward to what the modded bikes will bring. All in all great build.

Whats wrong with M2 bike? I reach the maximum RPM, release the throttle and rear wheel just locks. Its impossible to turn into the corner because bike just slides away.



In this video I didnt brake I did not downshift...not even reached full RPM...the bike just slid away when I released a throttle.

Im tried to adjust and for me not work.... I don't notice any difference between raising the value or lowering it.
also, if I try to touch the rear brake a little ... you fall instantly
Title: Re: GP Bikes beta17
Post by: KG_03 on February 11, 2020, 10:56:42 PM
You are not even able to trailbrake because if you do rear just slides away. Even on soft tyres.

I did not have the rear wheel traction/rear brake problem with the M2 (all aids off except for auto rider lean), but the front is still way too light. Headshakes all over the place and the front washes out as soon as I try to stand the bike up coming out of the corner.

What controller are you using? I have a custom one and need to have it at 100 procent direct lean. Did you change that or some other settings?

I am finding the steering input not as good as b16 as it seems less responsive at speed than before, almost like a milestone game where I need to add anti deadzone!!! Still good but if I turn up liniarity to compensate the front end is messy. Anything under 100% on direct lean is bad for my systems btw, too slow in response.

Not had much time in it so will play about with settings and get back about it.

The VR crashes are more realistic feeling now, look forward to this in other titles too.

New Assen track is great fun and I didn't know there were so many different configurations of this track over the years. As others have said you gotta work hard to not have the M2 rear come around on you when slowing and turning.

I mean that entire clip is  you on the throttle, at the exact point the bug doesn't occur...

The M2 is a bit broken at the minute with EB and stuff.

The 2005 Assen was the transition period, where the last half of the lap was nearly done to the new layout, but the first half remained. Best of both worlds 😎

Post by: poumpouny on February 12, 2020, 01:17:59 PM
I also found the M2 rear a bit agressive but since i never ride a Moto 2 bike (even if i would love to  :P ) i don't know if it behave like that in real world or not, anyway Moto 2 bike is know to be very rear sensitive especially at the time Honda was the engine supplier (cbr 600 engine) and even the road homologated Cbr 600 rr was butal engine brake  !
Title: Re: GP Bikes beta17
Post by: KG_03 on February 12, 2020, 02:30:36 PM
Its hard for me to say. I can understand that if I brake hard and due to weight transfer the rear loose grip. But not if I release the throttle in the lean 🤷‍♂️

Post by: Myst1cPrun3 on February 12, 2020, 03:28:05 PM
The honda moto2 engines were actually detuned compared to even the stock cbr600rr engines, rumour was about 125bhp at rear wheel.

The triumph makes about 138-140 for comparison.

im on the brakes?!!? wtf are you talking about do u realise what corner that is? i changed down 2  gears u can even see that  go specsavers or something never seen such a  comment in my life. i have NO ISSUES riding this bike, but i suppose if u fly into corners smashing gears down at 17,000 rpm, yeah the rear will slide out, plus u can hear it when its happening? just rev match on downshifts and it wont happen

Obviously none of you have raced a bike before? just ridden round roundabouts with 15 degree lean angle at 20 mph thinking ur sick???

I have to agree with foul-mouthed connorhall70 on this one, I have no problems riding this bike. I stated in an earlier post that the front is still giving a bit of chatter but it can be worked out with a good set up and as far as the a$$ coming around just match your revs like Conner says.  #LEARNTOLIVELEARNTORIDE

Those complaining..... This is what the slipper clutch settings are for guys. Set the slipper clutch how you like it and you shouldn't have any problems with the rear stepping out uncontrollably for you...... I think many of you have been so used to arcade bike slipper clutch physics that you're lost when it comes to a realistic simulation of the slipper clutch, one or the other reasons is going off here I believe? Unless Piboso has screwed up the slipper clutch simulation & settings? ;)

Anyway. For most of the modern bikes, the slipper clutch should be under ECU control and adjustments, not mechanical. Apart from the different clutch parts, mechanical clutch settings are for the more classic bikes not the modern ones. Not tested beta 17 yet, so I don't know if both versions have been implemented or just a mechanical version for adjusting in garage?

You've completley missed the point of the entire thread....

Not on about smashing down the box at 17000rpm and screaming into turns...

This is about going round the turn, middle of the rev range, no input, and the back end just locking up.
Now you don't need to be a professional racer to see that it's quite clearly not how a bike should behave..

Seeing as it's an issue multiple people are having, there is clearly an issue. Just because you don't have the issue doesn't make it imaginary.there is even a video showing the issue, so maybe it's you who needs Specsavers. (I already went and got my shiny glasses last month 😂)
I don't have cholera but it still exists.

As for racing bikes and roundabouts, it's irrelevant really. We're all here because we like motorbikes, usually like racing, and usually understand how a motorcycle works.
No one is better because the have a race bike, and no one is worse if they have a learner bike on a roundabout. We're all equal, and we all have different experiences, both in the real world and in the sim, and we can all do some research to see what's right and wrong handling wise.

Speaking of right and wrong, there is literally no need to be so agressive and disrespectful. Maybe if you actually spoke to prove like civilised human beings they may take you seriously.

Yep slipper clutch is supposed to be adjustable, and adjusted in the garage.
It seems to help when setup right, so I can only assume piboso has the base values wrong.

That being said, a bike without a slipper clutch doesn't behave like this so I don't get why the bike with it would, at any points.

Unless there's some backend physics to extreme values I'm missing?

@Mystic: When you say a bike without a slipper clutch, what bikes are you talking about? All 4 stroke bike engines operate a slipper clutch either electronic or mechanical as far as I'm aware or the rear end would very likely end up killing the rider at some point.

There are a few machines, the most notable in my memory would be Brad Vickers CBR he was on at darley and Scarborough last year.

Every time he went into a turn the rear was locking and he was dipping the clutch, and when he didn't the rear hopped, and the engine even seemed to die and jump start at some points.
Now I didn't get to look or ask about it, so I can't say for certain, but it definitely seemed like there wasn't one.
I also believe my CBR has a standard clutch in it.

(Any 4 stroke that has a slipper clutch cannot be bump started due to the clutch slipping preventing the bump happening. Hence why clutches on grand Prix bikes are locked, (often see mechanics fiddling with a pin on the side of the bike) or they start directly from the crankshaft)
That much I do know

that being said I am a little unsure of the physics behind these, hence why I'm asking. Although I don't need to be sure of things to know that the M2 has some issue with EB. Whether its actually the clutch IDK.

I'm not sure what the modern 4 strokes are like to bump start but for sure the classic 4 strokes you could easily bump start those bikes.

But I'd doubt difficulty bump starting a modern 4 stroke bike has actually anything to do with the slipper clutch functionality. It's maybe something to do with the fact that modern bikes are probably not made to be bump started......
The pressure to make the slipper-clutch slip is far greater than anything a human could apply through simply bump starting a bike.
Title: Re: GP Bikes beta17
Post by: h106frp on February 12, 2020, 07:40:01 PM
From reading up in the past;
The slipper is a dog clutch with a straight face on the normal driving face and a ramp on the back face, a ball is used between the ramp face and the clutch pressure plate such that as the ramps drive around under back torque it lifts the pressure plate and dis-engages the clutch. The point at which the back torque dis-engages the clutch is controlled by adjusting the clutch stack gap (pressure plate travel).
45 degrees appears to be a stock value and still allows for roller starting, making the angle shallower allows a much lower actauting torque but the higher slip can lead to overheating and the need for starting to be crank driven.

Most road bikes pre 2010 did not have slipper clutches and dumping through the gears without rev matching easily locked the rear, must-have after market add-on for any big twin :-)

Also: slight bug on 2005 Assen, when in spectator replay camer (and occasionally TV cam also):

Sometimes the cameras flick in-between 2 cameras, I'm guessing the bikes position on the track triggers one camera, and then goes immediately back into the other trigger zone. Can be quite jarring and unimmersive sometimes.

Seen here (second lap spectator camera)



Loving the new beta so far, just a few things to relearn and understand, but nice work :)

That (underlined) is obviously wrong. Also, I don't think there's such a thing as an "electronic slipper clutch", unless of course you are referring to electronic engine brake control (which is definitely not a slipper clutch, even if it tries to solve the same problem).

Max/H: Noted and I stand corrected. Thanks guys.  ;)  8)

Having tested the slipper clutch settings last night, I think the slipper clutch settings are incorrect somewhere in game, either bikes physics(probable cause?) or hardcore simulation? What do you guys think?
If I remember rightly, the slipper clutch is supposed to smooth the transition to the rear wheel of the back torque from engine braking either cause of down shifting or sudden throttle lifting, and the racing version of the slipper clutch can be adjusted to do that no matter how fast you change down gears into corners to avoid the rear locking-up and sliding away from you, it's just a matter of how you like the slipper-clutch set-up for your riding style.....
The current parameters/settings for the in garage slipper-clutch don't allow that smooth transition without very delayed down-shifts(okay for casual public road riding, but for aggressive racing gear shifts not so good).

What do you guys think?

PS: Shouldn't there also be an option for a racing slipper clutch to define the number and thicknesses of the plates too?
Title: Re: GP Bikes beta17
Post by: BOBR6 84 on February 13, 2020, 11:53:16 AM
Slipper clutch stops the rear locking but doesn't stop sliding. Probably slides more if you are aggressive with the downshifts. Especially if you rely completely on the slipper.

Be interesting to hear from somebody using a clutch lever on a control system.. if you can modulate the clutch use any better.

Iv always used an xbox or similar controller with the clutch on the right thumbstick. Not much modulation and requires careful small movement compared to a full real lever.

Be interesting to hear from somebody using a clutch lever on a control system.. if you can modulate the clutch use any better.

Iv always used an xbox or similar controller with the clutch on the right thumbstick. Not much modulation and requires careful small movement compared to a full real lever.

Absolutely agree with you Bob, but I hope you'll agree with me too that when the rear is sliding the rider can control the slide, whereas when the wheel locks up, and is skidding, it is very difficult to control and will usually lead to the rear completely breaking away, hence the implementation of slipper clutches. Big difference between sliding and skidding the rear end when it comes to a rider being able to control the reaction well, yes? :)

Yeah of course I agree!

So is the bike in-sim locking the rear and skidding? Or is it just sliding out as the rear wheel slows?

The other point is that you can get the same effect by releasing the clutch lever slowly on your final downshift before the corner on the brakes. Whereas with a slipper you can release the lever straight away.

Just wondering if it helps in game having more modulation on the clutch

I think that apart from introducing the slipper clutch, the clutch system should also be improved and that it be configurable in the same way as it is in real life.
I have come to configure the cfg of my bike so that it works very well, but the problem that the clutch can only be touched from the cfg. that if, if you continue reducing the 6 gears sharply in a braking, the wheel slides ..... it makes it less abrupt but it continues to do so.

Speaking of clutch...

I'd like to see the bike shop the clutch automatically on launch control. At the minute of you dump the clutch like you do in the real world you either stall or flip.

Launc control automatically adjusts the aids also, such as anti wheelie and TC, bagged on preset values. (It limits wheelies to certain angles and so on)

While what we have here is launch control, it's called 2step launch control, and is used in cars, as it's not sophisticated enough for motorcycles.

The current iteration for me provides no benefit to it's use as we manually have to slip the clutch on launch anyway.

The clutch is still used in manual mode for launch control

Yes at the minute it is.
But in a motorcycle once the initial lever is dumped the ECU electronics take over and manually adjust the clutch, throttle, and assists to achieve maximum acceleration.

The 'launch control' in gp bikes is just a second rev limiter which is what cars use. Bikes do not use this

I mean sure there is a secondary limiter, and it disengages I'm a certain gear like in gp bikes, but there is much more going on in the background and it doesn't just limit the revs is my point.

I'd say it is locking the rear wheel right now Bob(unless one rides it like a pussy. Lol! ;D ), but Piboso has already stated in the beta17 changelog that the slipper-clutch sim isn't working correctly right now and he'll update it in a future release(Hopefully next release?).... Nothing changes does it. Lol! ;)

Release notes updated, with info about the rider lean aerodynamics effect and direct steer changes.

What does that do?

Quote from: changelognew: possibility to adjust the onboard views position
How does one change the position?

Quote from: PiBoSo on February 11, 2020, 03:41:17 PM- the rider lateral lean now affects the bike aerodynamics, shifting the bike's center of pressure
Does the riding style have an influence on this (dangling leg for example)?

Edit:
Just did the first proper fast laps with the new beta on my favourite (unchanged!) bike (KTM MotoGP) and I don't see much difference in the rear susp. At least not on that bike. A little bit less stable maybe but that could just be me being out of practice or not remembering what my precise setup was.
What exactly is wrong with the new simulation and does it apply to all bikes in the same way?

Never had issues with launch control. You have to be very sensitive with the clutch, actually I don't even need it
