this topic for discuss GPBikes beta6c discussion.

my first question, Chassis flex only lateral side? if can use vertical flex, it maybe good feeling when junp randing, washboard kerbs...

[HornetMaX]

As far as I can see, only lateral flexibility of fork and swing arm has been introduced. To me it's all we need.

What do you mean with "vertical chassis flex" ?

MaX.

[Yohji]

so, now fork and swing arm flex to left or side(lateral) its not flex to up or down(its mean Vertical)?

in cfg file, only lateral frex.

[HornetMaX]

Swing arm vertical flexibility is likely to be irrelevant, as anyway you have a suspension attached to it.

Lateral for both fork and swing arm is all we need (and have).

If you wanted to be and absolute sim maniac (which I don't recommend for GPB), you should separate lateral flexibility from torsional flexibility and you should also include fork bending under longitudinal forces (e.g. when braking hard).

I think the current implementation (lat flex only) covers 99.999% of our needs.

hm,

I tryed edit flexing, maybe stiffness 0=flex off.


so, I want debug for flexing,,,

FYI, professional simulators only simulate the front flex ( the very few that simulate chassis flex at all ).

[PiBoSo]

maybe stiffness 0=flex off.

Correct.

beta6 Correspondence slipper clutch? I feel difference from beta5

and beta6 still strange motion in up hill & down hill its cant fix now...? and what its cause?

No changes in the slipper clutch simulation.
