Abstract
This simulation was validated by comparison with tests using an instrumented vehicle. A combined program has been conducted by Calspan Corp. & the Harley-Davidson Motor Co. Inc. to study weave instability of motorcycles at high speed, which is characterized by coupled steer-roll-yaw motions. The influence of several motorcycle characteristics on weave instability has been evaluated in the context of system performance by simulating high speed disturbance-response behaviour.
