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
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.
