Hi everyone,
As you already know, i'm struggling with the hardcore mode since month, i first know about it with klax's thread :
I found it pretty cool, and start to learn it. at that time, i still played gpbikes with my DIY handle bar : , but since it has no FFB, it was too hard to know where the lean maximum angle because of lack of bike feedback (hard for me, but klax manage to ride in hardcore mode with gamepad so it is surely possible).

Then come to me the idea to build a handle bar with FFB. Having poor knowledge in electronics, mechanics etc, i just buy a logitech G920 wheel and is making a handlebar that could be "mounted to the G920" (still in WIP so i'm still playing with only the wheel itself)

I play first with DST mode, cause klax used it in his thread, but found soon it was so difficult. Then I tryed DSA  but idem get me more frustrated. i pratically try it every day (change setting, whatch replay, the re change setting, re-watch replay .....etc)  found it too much frustrating and go back to Normal Steering mode.

My main problem was to keep the bike up at a given lean angle, in DST mode you can do it with the "klax method", wich consist of using the throtle in corner, personnally i found it very unaturral as you don't do that IRL, in IRL you throtle, hard brake, realease gas (on a hard corner) and then re-accelerate only in the corner exit. With klax method, you had to keep throtle during all the turn.

I was very near to give up, then yesterday, i finally found setting that allow me to drive finally naturally and do 1, 2 or 5 lap without crashing. i'm a slow rider (even with normal steering) i'm 10 sec slower that most of online riders, now with Direct Steering, im 10 to 15 sec slower that in Normal steering mode but Direct Steer is so much fun that i don't really car about laptime for now, i think i will be faster with practice but first of all it is pure pleasure, you have to really ride the bike in each corner, it was like the moment when i switch from Moto GP to Gp Bikes, so i wan't to share my setup here to help in case someone wan't to go with Direct Steer.

1. Rider lean :

I think a head tracker is a must have if you want to go with Direct Steer to controll the rider leaning (the auto rider lean doesn't work when you are in hardcore mode so you're ridier is just hanging on the bike in turn and you loose almost 10° in maximum lean angle, also the replay look very ugly with the rider sticked in the bike  ;D . don't be worry, i don't have fancy headtracker, i just use my phone (with a gyroscope) and a couple of software (ed tracker is surely the best option and cheaper one but for me who is in the middle of the Indian Ocean it is a real problem to buy thing and ship it here.

So this is a tutorial to make your DIY headtracker with your phone :

2. Wheel controller : Unless you are Klax, i definitely recommend you to play hardcore mode with a Wheel or a DIY handlebar with FFB, i set my FFB setting force at minimum force, otherwise the wheel is incontrollable and i don't think that IRL handle bar produce that much of resistance.

3. Direct Steer mode :

After playing almost 2 month with both mode, i finally choose DSA (Direct Steer with Angle), because you controll directly your lean angle with the handlebar angle so you don't need to play with throttle in turn to keep the bike up. The problem is that IRL the handlebar max angle is aproximatively 25°, but when you gain speed you only use 5° to 10°of it, so if you go with the Piboso's default steering angle setting ( Directsteer_maxangle=20 ) it is almost impossible to keep the bike up past 30° lean, you can do it IRL because you have lots of feedback from the bike, but with gpbike you don't have these feedback, so 5 to 10° is definitely not enough to controll the bike lean and that's why i was keep crashing and get frustrated during 2 month. Yesterday, i open up the profile file, put 80° as max steering angle, fired up Gp bikes and tadaaaaaaaaaaaa got i working.

Edit : You have to re-calibrate your wheel each time you change DSA max angle

i'm now able to reach constant 50 to 55° lean angle and surely with practice go past 60°.

Here is the code you need to put into your profile.ini to enable DSA mode with my setting, wich you will find in : Documents/Piboso/Gpbikes/profile/profilename/

Code: [Select]

4. Bike :

For now i made my test with Moto GP mod bike and GP 500, i'll complete testing with other bike (especially smaller bikes) but for now, i found that the GP 500 category is the most easy bike to start with Direct Steer (the default Varese or the mod bikes).

5. How you lean your bike :

The fantastic thing about Gpbikes is that it works really like IRL, so with your headtracker controlling your rider lean F/B/L/R and attached to your head or your shoulder, you start leaning by leaning your body first, then turn slightely the handlebar until you find your lean angle limit, or the lean angle you want. I'm using MAX HUD to show my leaning angle but it could distract you when you ride.

Disclaimer : Despite DSA is 5 times more accessible with this setup, that doesn't mean it is easy, it still need lots of practice, so I'm no responsible of suicide statistics grow up after this thread  ;D

Hope it help and sorry for my poor english.

as this topic, , i got problem softlocking my wheel (logitech G920) below 180°. I'm searching for a solution since one month, i've try everithing even the logitech official forum, but didn't find solution. I posted my problem in a french simracing forum and gyus says that they didn't manage to soflock any wheel (Commercial, and even DIY wheels) below 180°. I don't mean here the efficient range, i mean the softlock (when the FFB block the wheel rotation at a given degres of rotation).

So i just wan't to confirm if what they said is true (180° is the minimum softlock limit).


Hi there,
As i think you know i'm a fan of hardcore simulation, i'm still learning DSA/DST and even if i like thing to be the harder way i think DSA/DST is way more to difficult to handle, mainly because of the lack of feedback you get from the bike in DSA/DST mode.

So not talking about hardcore counter steering wich i think people is doing instinctively ( i think 70% of people riding a bike don't even know they turn the steering the opposite way when turning)
will it be more natural and more accessible to a lot off people to get a mix version of DSA/DST, to the Default normal steering mode. Let me explain :

In Default steering mode, you are dictating the bike leaning with your controller, and the software do the rest to match the steering, rider leaning and balance of the bike ... The problem is that you do not have to worry about lean angle limit so you can just push your joypad ton the maximum on a hard turn and wait the bike to turn without worriyng about nothing else that your trajectory.

In DSA/ DST you have no leaning angle limit but you have to control the angle or the torque applyed to the handle bar and guess the resulting bike leaning, wich with a very limited feedback from the bike is very difficult and not natural at all.

So why not take the Default steering mode and just remove the bike lean auto-limiter, with that you are dictating directly the bike lean without worrying about countersteering, but you have to limit you lean angle yout self.  So for example on a wheel, say you put a 140° angle limit for your wheel wich is a normal moto gp lean angle limit (70° left and 70° right) so you know (depending on wich bike you ar) how much can you go with leaning.

Thanx :)

Custom hardware / Logitech G920 wheel stacked at 180° of rotation :(
« on: September 05, 2017, 08:16:12 AM »
No matter what value i'm putting in the Logitech Software, i'm always in 180° of rotation in gp bikes (90° left and 90° right). I'm training with DST and DSA and it really just kill the mode. The problem is that the wheel is "soft locked" into 180° but only 40 degrees (wich i put into the Logitech software) (20° Left and 20° Right) is used by GP Steering which lead to a huge deadzone in each side !

Please Help

Custom hardware / Counter steering with FFB controller prototype WIP
« on: July 27, 2017, 03:09:54 PM »
Hi guys,
i'm working on a serious controller prototype for a counter steering with FFB experience for GPbikes. But to avoid complex engeneering with servo motor etc and keep the cost viable for an eventual commercial plan etc.... i'll be making an "attacheable" system to a Logitech G25/27/29 Wheel for the FFB. of course if the prototype is good enough, i'll be planning to sale it but for now it's just a prototype.

As DD, i'll be using real motorcycle part for handlebar, lever, etc ... and 3D printed for specific parts.

I cannot say yet how the counter steering will work, but it will be a very simple but efficient way to controll gpbikes (no load cell, no complex axes .....)

I'm still on the mechanical engeenering (waiting for my 3D printer to be delivered) for the linear to radial movement translation for potentiometer.

Here i'm now

<a href="" target="_blank" class="new_win"></a>

Just by curiosity, i know Piboso start the adventure alone wich lead us to our wonderful sim, but now is he still alone or is he having team now ? If he's alone he must be a super man !

Just found that tutorial, tried it and it work fine ! tick freelook and freetrack in simulation menu ! hope it help and no your are not ridiculous with your phone on top of your head  ;D

Custom hardware / How to control free rider look with joystick ?
« on: June 13, 2017, 02:18:36 PM »
I'm trying lot of thing with my smartphone gyroscope and the software monect (who transform your phone into a game pad). So my question is how i can assign my joystick axis to the freelook, i know there is an option "joystick" in free look but i don't know it is assigned to what joystick and and i don't see any option to assign it!


Bikes / Fantastic Tutorial for bike modder (eng, geom, etc ....)
« on: May 26, 2017, 09:32:36 AM »
Hi, every one.

I just want to share this as this could help so much newbie modder like me :

This is for Mx bikes, so oriented in dirt bike, but can be adapted to gp bikes, at least explain you how bike ed and enged work (wich is pretty difficult due to lack of online ressource to learn it)

Hope you enjoy ! :)

Bikes / My first attempt to mod bike (HONDA CB 400 SF)
« on: May 04, 2017, 12:13:08 PM »
Hi everyone,

i'm starting, and learning in the same time, to mod a bike for gp bikes. As i think everyone do, i start by my own bike (i think it's best to realy fine tune the physics etc, as i ride this bike in real life).

I'm now on the modeling phase ( i took on model on the net wich is a 2006 model as a base) but my own is a 1996's one, with good old carburetor :) so i just keep the little parts (engine, frame, light etc)  and re model almost all major parts. i'm still at a very high polycount (because the net model is not modeled for game at all). hopefully i'm working with c4d and Zbrush and his revolutionaly Zremesher tool.

This is my real bike :

this is the model i found on the net :

And the remodeled one (still in WIP) :

one thing i dont really understand is the 1st person view model. Do i Have to make a completely separate model ? if so, wich part did i need to model for the 1st person view.


Bikes / Help me to start moding bikes
« on: April 27, 2017, 11:53:58 AM »
Hi, everyone.

I'm a moto GP fan, of course a Gpbikes fan, and a 3D Artist in real life. I would love to mod bikes (and track later) for the community. I'm not a develloper at all (juste some test in UE 4  and using template and some basic flash skill) so my question is for Gp Bikes, after i finished modeling and texturing the bike in my 3d software :

- i export in wich format for gp bike ?
- wich software to use to do the bike physics ?
- do i need lot of coding ?
- is it doable for a designer (not develloper at all) to mod bike from A-Z for gpbikes ?


Bug Reports / Core.exe every time i try to join any server Beta 11b
« on: March 06, 2017, 07:15:33 AM »

Try to race this sunday after installing Beta 11b,  but every time i try to join a server i got a core.exe

What i did :

- Reinstalling (renaming the old folder, deleting the Piboso folder in document, then reinstalling) and then add bike, paint etc
- Reinstalling without any bike, any plugin or any paint.

in the 2 case, i always got each time a core when trying to join any server.

No problem when testing offline.


Racing / Cannot see some server
« on: February 12, 2017, 01:17:37 PM »
Hi all, i'm trying to play on line, i see a server (in the web stat list) which has 4 players, but when i connect from gp bikes, i cannot see the server in question, i double check i have the track and the bike but i cannot see the server in gp bikes, just in my web browser.
The server in question is : kuroitori jp

Any idea ?

Custom hardware / GP Bikes Controller from recycled old materials
« on: November 03, 2016, 02:09:01 PM »
Hi there, i'm new here, i bought gp bikes for about 1 and half a mounth, i played 2 times with gamepad and notice that it's just too realistic (physics) to be played with joystick, i've searched for bike controller in the web and appart some custom made(too expensive for me)  and the truthmaster shit one (that is no longer on sale) it simply doesn't exist, so the only way was to make it my self.

I've copied the AI System (double dragon) for the pedal. Mine looks prety ugly, no 3d print here but it works well, and it's the only thing that matters to me.

Tested it this WE and it is thousand more precise and fun than gamepad.

PS : I don't know how to attach youtube video directly to the thread !
