Motorcycle Chain Sprocket Kit For Honda CG125 Suzuki GN125 WY125 ZJ125 CD70

The function of a motorcycle sprocket includes:

1. Power transmission: The sprocket connects to the engine's crankshaft or gearbox output shaft via a chain, transmitting power generated by the engine to the rear wheel.

2. Gear ratio adjustment: By changing the size (number of teeth) of the sprockets, the gear ratio can be adjusted to suit different riding conditions and performance requirements.

3. Speed variation: In gear transmission systems, different sizes of sprockets paired with varying numbers of chain links can alter the rear wheel's speed and torque, enabling acceleration or achieving higher top speeds.

4. Load-bearing and durability: Motorcycle sprockets must withstand high torque from the chain and impact forces during high-speed rotation. They are typically made from high-strength alloy steel or other reinforced materials to ensure durability and reliability.

In summary, motorcycle sprockets play a critical role in the entire transmission system, directly influencing power output and the vehicle's performance characteristics.
