Unlike the timing belt, the drive belt is responsible for transferring power from the engine to the rear wheel. Most commonly found in scooters and some cruiser bikes, the drive belt is often a toothed belt made from high-grade rubber and designed to handle high torque. The advantage of using a drive belt over a chain includes lower maintenance, reduced weight, and quieter operation. Moreover, drive belts have a longer lifespan compared to chains, making them an appealing option for many riders.

In a CVT system, the transmission belt operates between two pulleys that can change diameter. As the engine generates power, the primary pulley expands and contracts, causing the belt to move up and down its sides. This movement adjusts the gear ratio according to the vehicle's speed and engine load, allowing for optimal engine performance and efficiency at all times. The belt's ability to flex and adapt is what makes the CVT smooth and responsive, eliminating the shift shock commonly experienced in traditional transmissions.
