What would cause a bikes front forks to get really, really soft. We were riding at Watkins In CO, lots of jumps, and her 225 just gave out. I know it is not a MX bike but she doesn't weigh 130 ( do not let here see that). The bike no longer has any resistance to the front forks. DUmb question I know but the 426 takes the jumps and wants a lot more so I dont really know what to think.
