Hopes for a realistic motorcycle sim
Luke Phillips asked for a truly realistic bike sim, and others said GP500 and Superbike titles were closer to arcade games. The thread became a long argument about countersteering, gyroscopic effects and bike balance between riders. Thrustmaster's motorcycle controller was briefly mentioned.
Automated summary.

GP500's a few years old - but there's mods to bring it up to 2002 spec.
Excellent title - pity the multiplayer's a bit shoddy

The truth is out there.....You just have to look in the right places.....and
ask the right questions.
hello,
if we compare GP500 and SBK to how handle a real motorbike,
they are pure arcade.
I don't knowif you know how to drive a motorbike, but you should know
that to go left on a bike you have to first steer toright, to make the
car lean to left, then let the bike turn by itself ;o)
They are othe important thing that are never been simulated like, the
gyroscopic effect.
Other thing, when cornering on a bike , if you brake too much withthe
front brake ( withoutlocking ) the bike un-lean ,or lift up if you
know what i mean ... but if you brake with the rear brake, then bike
lean more, and could even slide from the rear ( Mc coy style ;o) ).
They many other things that are not simulated in GP500 and SBK.
When i play GP500 and SBK, i feel like drving a car not a motor bike.
btw, i have a Suzuki SV 650 S , i'll buy a Ducati 996 some days ;o)

Actually he's partially correct. You don't have to start a turn by
counter-steering,(actually a tug on the opposite side of the handlebars in
relation to which direction you wish to turn) but if you do, it initiates
the weight transfer that tiny bit quicker and thus speeds your turn. A
handy gimic that most road racers have learned. Convincing a street rider
that it works is sometimes difficult.

I know about and understand countersteering Dave... don't think I've ever
done it myself, though. As I learned how to ride a motorcycle in motorcross,
I assume I ride from the hip (don't have a road bike anymore and never payed
attention to how I rode back when I did).
All of this, however, is beside the point. Read what Sebastien said again,
I'm sure the penny will drop... ;-)

dave henrie
He's totally correct actually.. well basically. When you counter steer the
bike, its something you hardly notice. A time where you will notice if there
is a change of direction and you front wheel lifts off the ground, it will
steer the oppisite way... eg if you are in a left hand turn and are
accelerating while changing direction into a right hand turn your wheel will
land turning to the left..

Why partially ? I'm totaly correct, i'm driving motrcycle for some
years, i tried some racing bike on racing tracks.
You can't take a turn WITOUT counter-steer, except when you are almost
stoped.
And that's true for all the 2 wheels vehicule, even bikes and vespa.
But the less the bike weigh the shorter the counter steer is needed.
I even counter steer with my mounain bike ;o)

So, presumably, you to go left on your bike, you first steer to the right,
which makes "the car" (presumably your car, back home in the garage) lean to
the left, which in turn allows the bike to go through the turn by itself.
Rather strange if you ask me... ;-)

I think that since many riders don't even know what CS is, they can't use it
everytime. Your body, however, may know more about the laws of physics than
your mind. While I had to learn to countersteer, I never had to learn to
lean into a turn. I suspect that even if we are not physically yanking on
the opposite bar, we are inducing some countersteer by beginning to lean or
shift our weight as we start a turn.
Perhaps that's Seb's point.

I'd like to see this, but I'm pretty sure a counter-steering bike sim,
wouldn't go down too well with most people. :)

I think GP500 is pretty good, actually. it's far from being GPL,
sure, but in general, when you "do stuff", you get the right sort of
results.

no bike these days. too bleeding expensive. used to race 600s,
though I'll admit I wasnt particularly good at it. :)

it's close to impossible. I do insist that everybody does it this way
though, conscios or not. steering with body weight is just too slow. :)

Forget the gyroscopic effect, it's a red herring and is not the reason
you countersteer, balance is the key. Which also explains why the bike
will un-lean when you use the brake. If your lean increases with the use
of the rear brake, I can only assume that the rear wheel is sliding or
drifting.

Weel, the motorbike didn't turn at all ;o) The gyroscopic effect was

handling on the brakes depends on a lot of things, I think. at least
for the front brake. I never touch the rear brake myself, but
applying the front brake in a turn will make the bike stand up with
some tires (metzelers, for instance), where other tires will make it
lean more (Dunlop's 207GP is an example of this). probably depends on
the steering geometry too. the above was true for the CBR600 at least.
can't say I understand why, though.

if I understand you correct, that has nothing to do with gyroscopic
effects. are you saying the forks didn't turn? in that case, the bike
can't turn, because the front wheel can't turn.
it's perfectly possible to steer without counter-steering. try
steering the bike without holding the handlebars. you'll see. :)

I have it in the shop, had a brief look at it without actually
connecting to a PC and firing up a game or anything, and it looks like
it *could* be a decent product
Of course, like most Thrustmaster products, it's got a very "plastic

Gyroscopic effect : force that counter act other force that tend to

At low speed certainly, but certainly not at high speed, if drivers
lean on the bike, its to lower the gravity center so the bike can take
the turn faster without need to lean the bike more, that's not to help
the bike to lean .

Ever tried to ride a bicycle through a puddle and watch the resulting

forth to keep the wheels below the center of gravity, much the same
way you balance a broom in your hand. That is why the bike don't fall.
Gyroscopic effects are small, if you don't believe me, read this QA by
a bikeriding physics professor:
http://ist-socrates.berkeley.edu/~fajans/Teaching/MoreBikeFiles/BikeQuestions.htm
And if your physics is up to scratch, read his paper:
http://socrates.berkeley.edu/~fajans/pub/pdffiles/SteerBikeAJP.PDF
A guy called David Jones also made bicycles with extra wheels rotating
in the opposite direction to cancel out the gyroscopic effects. It
turned out the handling characteristics were only sligtly different
from a normal bike, and could be ridden no-hands.
