G-Forces on a track

[FROSTY:Me]

I heard that F1 car drivers pull something like 4g under heavy braking

Of course there will be some increased G-Forces depending upon how you are riding; but not anything to cause you any G-Force related discomfort.

It's not exactly on par with an F16 fighter jet or taking a rocket to the moon!

Unless you brake using a concrete wall. I imagine that would produce some pretty intense G-forces.

PB mag years ago reckon 1.8G's on the front brakes max.

Some people have actually collected this data. The values are for that specific racetrack but generally speaking that's what you can expect on any race track. Have a look:

Don't quote me cos my memory is a bit hazy these days, but I remember reading an article years back where on the banking at (I think) Daytona, the suspension was fully compressed and some of the riders were "greying" out. When this started happening, they took the bikes off the banked track.
The banking needed very high tyre pressures to cope with this and so screwed their handling on other parts of the track

Yes, because of the aerodynamic downforce from their bodywork and wings. That's basically why an F1 car can beat a MotoGP bike's lap times by about 20 s.

I heard they get 1g by just taking their foot off the button

1G.

You may notice it pulling you into the seat.

Next thing you'll be claiming that the tyres are subjected to 14.7 psi on the outside when riding on a track!

G force so great that it can throw you off the motorcycle.

Go into the thread disproving Skidmarks claim of stopping from 60kmh in 2m...

Legend has it, that was rear brake only too

Inconceivable!

Inconceivable!

I won't have a bar of it !

Not uncommon to see 1.4G under brakes.

Cornering (flat road) at 60° bank would be 2G. A more realistic 45° bank will be approx 1.4G.
