Will this sprocket fit my 110cc pit bike?

Yes, this 420-15T sprocket is compatible with pit bikes ranging from 50cc up to 160cc, including your 110cc model, as long as it has a 17mm countershaft and uses a 420 chain pitch.

How does the 15-tooth design affect my bike’s performance?

The 15-tooth sprocket improves your vehicle's top speed and reduces engine vibrations at higher RPMs, giving you smoother rides and better cruising capabilities.

Is this sprocket durable for off-road use in wet or muddy conditions?

Absolutely. It's made from heat-treated, high-strength steel with an anti-rust coating, which means it resists corrosion and stands up well to harsh all-weather and off-road environments.

Will installing this sprocket require extra maintenance?

Thanks to CNC machining for precise fitting and smooth chain engagement, this sprocket minimizes wear and is designed to require less frequent maintenance compared to lower-quality options.

Can I use this sprocket with brands like TaoTao or SSR?

Yes, it's fully compatible with several popular brands including TaoTao, SSR, Apollo, Lifan, YX, and Zongshen, as long as they use a 420 chain with a 17mm shaft diameter.
