MSF (Motorcycle Safety Foundation) Rider's Course Practice Test

Releasing the clutch lever immediately after starting the engine can cause the motorcycle to be in gear, which can be dangerous if the rider is not ready to control the motorcycle's movement. While options A, B, and D are also potential consequences of releasing the clutch lever too quickly, these are not the primary reason why it is important to not release it immediately after starting the engine. Instead, the main concern is that the motorcycle may be in gear, which can lead to unexpected and potentially dangerous movements. It is important for riders to always be aware of their motorcycle's gear and be prepared to control its movement before releasing the clutch lever.
