Final answer:
When a motorcyclist pulls back lightly on the right handlebar, it creates a torque on the motorcycle, causing it to tilt left and produce a left turn. This technique is known as countersteering and is used to initiate turns quickly and efficiently.
Step-by-step explanation:
When a motorcyclist pulls back lightly on the right handlebar, it creates a torque on the motorcycle. This torque causes the motorcycle to tilt to the left, resulting in a left turn. This phenomenon is known as countersteering.
Countersteering works because of the gyroscopic effect of the spinning wheels. When the motorcyclist initiates a turn by pushing on the right handlebar, the bike's front wheel leans to the left, making the motorcycle start to tip in the same direction.
The countersteering technique is used by motorcyclists to initiate turns quickly and efficiently, especially at higher speeds. It allows the motorcyclist to have better control and stability while navigating curves and corners on the road.
