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
