The lift of the sidecar during a right turn is greater when the sidecar is empty or light.

• A. Not specified
• B. True
• C. False
• D. Depends on speed

Answer: (B)

When a sidecar rig corners, the forces from turning cause the motorcycle to lean and transfer weight across the wheels. The sidecar is fixed to the frame, so the amount of downward force on its wheel depends on how much weight is on that side. If the sidecar is empty or light, there isn’t much weight to press the wheel into the ground, so the lean and lateral forces of the turn can lift the sidecar off the ground more easily. A heavier sidecar adds downward force and inertia, making it harder for the wheel to rise. So, in a right turn, the sidecar tends to lift more when it’s empty or light, even though speed can influence the overall amount of lift.
