Sounds way too high...

F1 cars are not that high

i`m no expert, but it is an area i`m interested in and would have thought about 2 to 4 in the corners and not much more than 2 on a acceleration...I would think that the most g would be in braking.....
here`s a quote from a study of g forces i found in a book i have.... "It is not unusual for the effects of gravity (g-force) to exceed a factor of two on the Daytona high banks. This means that a Superbike and rider circling the banking at 180-plus mph effectively weigh more than 1200 pounds."
hope this helps

This is a wierd one, because you would assume that the g-force in a given corner would be greater than any experienced on a straight...but I get the feeling its a little more complex than that:puzzled:

Thinking about it (not for too long, my head starts to hurt) but I wouldn't be suprised if the forces experienced on acceleration and braking were quite a bit higher than those experienced by the rider during any corner...as mentioned by Uncle above, you may be able to reach 2g on banking, but on a flat corner, the limts of the tyre would not allow for significant g's to be reached, the bike would simply slide off the track.

With F1 cars, acceleration is comparable(ish) but we all know that their braking and cornering is something else, and a bikes rider would not experience anything as high.

I guess in the cornering department it comes down to tyres, so perhaps some of the big tyre manufactures would be able to help here? Might be worth contacting a few for info if required Jewell.

Where's Shazzam:lol:

I think they're specifically referring to the banked section rather than a flat straight?
