💡 What is a chain sprocket used for in small motorized vehicles?

It's a handy power transfer component that drives the drivetrain by linking engine power to the chain and wheels.

- transfers engine power to the chain - sets gear ratio with rear sprockets - durable, heat treated metal resists wear in off road use - common on dirt bikes, go karts, ATVs, and mini bikes
