This genuine KÜRZ, hard wearing sprocket is made of steel and will fit most pit bikes. 

A bigger front sprocket adds speed in each gear and more top speed, but may reduce acceleration. 

A smaller front sprocket reduces speed in gear and gives less top speed, but will increase acceleration.

  • Teeth - 17
