This reminds me of a problem Suzuki had with the first generation, long travel suspension, RM 250 MX bike. The rear suspension just didn't behave well on big bumps. Turned out the rebound dampening was excessive and the rear wheel spent too much time in the air before returning to the ground after each bump. A wheel in the air can't generate cornering force. I keep thinking that our situation is something like the Suzuki's problem.
